It is perhaps noteworthy that Dubinin (in "Ceramic Method of Gaseous Chromizing Steel",
1953) considers gaseous methods the most technically perfected means of chromizing; where.
as, in 1950, blinkevich stated chromizing in liquid or gaseous media was nonindustrial
although this is a difference of viewpoint or a real commercial development that has
taken place between 1950 and 1953.

ABSTRACT: In recent years several new carburizable steels have been
studied and introduced into production: boron -containing Cr-
Mn steel, 2OKhGR (0.0045% B), 30KhGT steel with Zr
18KhGTTs and 30 KhGTTs (0.09-0.18% Zr), which differ from
similar steels without Zr, such as 15KhGNTA, etc., by a lower
tendency towards growth of the grain. For the cementation of
steels new carburizers are being use& "sintin", a liquid mix-
ture of hydrocarbons, a by-product of the treatment of solid
fuel, and triethanolamine, a colorless fluid containing (weight
%) N 9.4. C 48.5, H 10, 0 32.1. Included are plans of equip-
ment for the production of neutral gas (diluting gas) and of
Card 1/2 kjln5 for the gas cementation and cyaniclation of parts.

Current Status and Problems in the Field of Thermochemical Treatment
Aggregates for rapid gas (ementation of gears with high-frequency heating
have been developed and introduced into the industry (automobile plant im.
Likhachev). (A drawing of the installation is included.] A new proc es s of
low-tej~hperature nitriding has been introduced. The possibilitv of applying
rapid nitriding of Mg-.(ast iron with spheroidal graphite is noted. The wide
use in the industry of the processes of calorizing and sulfidizing of steel and
cast iron and chromization and boronization of steel are pointed out. In the
very near future thermochernical treatment of metals and alloys on nonfer-
rous base will be used widely: nitriding of Ti and surface hardening of Ti by
means of oxidation. Among the promising processes to be named are also
the thermochernical treatment of ste6l with heating in the electrolyte by the
method of I.Z. Yasnogorodskiy. Bibliography: 24 references.

ABSTRACT: The results are described of the study of oxidation of
titanium in molten borax applying electric protection
and borating inside metallic boron powder in vacuum.
The experiments were made with forged titanium,BM01ten
from commercial titanium in a vacuum furnace with a
graphite crucible, containing 0.5 to 0.6% C; a forged
titanium alloy containing 0.5% W (produced by smelting
of commercial titanium in an are furnace inside an argon
atmosphere), forged commercial titanium and, finally,
a titanium alloy containing 2.5% Cr and 2% Al. To
prevent oxidation of the titanium in the molten oxygen
containing salts and to protect the surface from
corrosion damage, electro-chemical 2protection was applied,
the current density being 0.1 A/cm , the voltage

graphite rods serving as anodes. After removal from the
bath the specimens were covered with a layer of the
solidifying borax. The graphs, Fig.1, show the
distribution of the micro-hardness with the depth of the
diffusion layer for one of the tested alloys as a
function of the duration and the temperature of the
process; the graph, Fig.2, shows the change with depth
of the diffusion layer as a function of the duration of
the process at various temperatures; Fig-3 shows the
change in the surface hardness of one of the alloys as a
function of the duration of the pZocess at various
temperatures between 900 and 1050'JC. Results of
preliminary wear tests on one of the tested alloy8 are
given in Table 1,which show that treatment at 930 C for
six hours increases -the wear resistance by 37 times as
compared to equal non-treated specimens. Results of
wear tests of another of the tested alloys are given in
Table 2, P.56, and these also show appreciable increases
in the wear resistance of treated specimens. Numerous
micro-Btructure photos are included and spectral analysis
Card 2/5 revealed presence in the surface layer of 12 to 20% B.

129-12-8/11
Surface hardening of titanium by treatment in molten borax.
The results are also given of tests of borating a titanium
alloy containing 5% Cr in metallic boron powder in
vacuum. The micro-photo, Fig.?, shows that the diffusion
layer consists of three clearly pronounced zones, two of
which are bright the outside non-etched one is
separated by a line ui division from the inside,slightly
etched, zone. The graphs, Fig.8, give the results of
experiments of treating titanium in a mixture of 60%
borax and 4% B4C as recommended by N. P. Besedin and
M. Ye. Blanter. On the basis of the obtained results,
the following conclusions are arrived at: treatment in
molten borax applying electric protection is an effective
method of surface hardening of titanium and brings about
an increase in hardness from H V 250-300 to
HV 5
5 = 700-950; the wear resistance of thus oxided titanium
is comparable with that of case hardened or nitrided steel.
Treatment of titanium in molten borax reduces the strength
and, particularly, the plasticity and toughness,which is
attributed to an intensive grain growth in the process of
long duration heating and also with surface hardening',
Card 3/5 Titanium can be treated in molten borax at 900 to 930 C

129-12-8/11
-Surface hardening of titanium by treatment in molten borax,
2
for three hours with a current density of about 0.1 A/cm
Treatment at higher temperatures and of longer durations
involves a sharp increase of the brittleness of the layer
and also a reduction of the mechanical properties of the
titanium. Treatment of titanium in molten borax brings
about mainly oxidation, whilst boration is very slight
or even does not occur at all. Bright surface acicules
of the diffusion layer forming during such a treatment
consist of a solid solution of oxygen and titanium.
Hardening from the saturation temperature does not change
the acicular character of the micro-structure of the
diffusion layer. When treating titanium with Rolten
borax at an elevated temperature (1000 ~o 1050 C) and
high current densities (1-5 to 2.5 A/cm ) a thin and very
hard (2500 W non-etching layer forms at the titanium
surface; how ver application of such treatment brings
about intensive Aamage of the specimen surface. In the
case of borating of a titanium specimen c8ntaining 5% Cr
in boron powder in vacuum at 1000 to 1050 C a diffusion
layer forms at the surface containing a thin non-etching
surface zone of a high hardness (H V - 1000 to 1150,
Card 4/5 micro-hardness exceeding 2200). 5 The type of the

lattice and the parameters of the surface zone of this
layer correspond to the boride TiB; the disadvantage of
this method is the high temperature required for the
proSess. Hardening cfthe titanium can be effected at
800 C for durations of 6 to 9 hours in a bath containing
borax and boron carbide; however, this method is suitable
only for small components and, in addition, the surface
hardness increases only by HV 200 to 250 and by
300 to 500 HII*

ABSTRACT: The authors investigated processes of chromating and
borating steel by means of chromium and boron-containing
pastes and high-frequency heating. The experiments were
carried out with 12 mm diameter specimens of the steels
20) 45 and U 10. The heating was effected with current
supplied by a 60 kW7 350 kc/sec tube oscillator. The
constancy of the temperature was ensured by means of a
photo-electric pyrometer; the distance between the single
turn inductor and the surface of the paste was about
1 - 2.5 mm. The paste consisted of a chromium or boron-
containing powder and a fluxing medium. The following
conclusions are arrived ats 1) For chromating by means
of high frequency heating for a duration of 2 - 3 minutes
Card 1/3 at 1050 - 12000C a paste consisting of 75% chromium powder
or ferro-chromium and 25% cryolite with a hydrolized

Chromating and Borating of Steel, Applying High Frequency Heating
ethyl-silicate as a binder, is suitable. A chromated
layer 0.10 mm deep will be obtained by means of this
method for steel 20, heated to 12000C for 2 minutes, as
compared to 8 - 10 hours' heating to 10500C required in
the case of the current method of chromating. Howeverg
the surface of the specimens is not always as good for
this new method of chromating as it is for the ordinary
method. 2) For borating of steels by high frequency
heating at 12000C for 2 - 3 minutes, a paste is suitable
consisting of 50% boron carbide and 50% cryolite with
hydrolised ethyl-silicate as a binder. Borating by
means of this method of steels 45 and U-10 brings about
the formation of a layer up to 0.12 mm thick with a
hardness of about 1000 HvlO* In the surface zone of
the borated layer, borides of iron and boron carbide
were detected by X-ray analysis. A layer of an equal
depth (of a slightly different structure and of a
slightly greater hardness) can be obtained by means of
electrolysis at 9500C for 2 hours. Borating by means

TEXT- Information is given on results of experiments an titanizing of
08-and 50 grade steels in a molten salt bath. Titaaizing was successfully
perform;d--a-t 9500 and 1,1000C during 0.5 - 2 hours in a bath containing 80 -
90% molten sodium chloride and 10 - 20% fine granulated TIO.'alloy (containing
about 10% (at.) 02). Melting and utilization of the bath was conducted under
ari argon shield,- It is desirable in further experiments to investigate the
possible utilization of the bath without a shielding gas. It is also re-
commended to check the'-possibility of replaoing the powder of a specially
molten titanium alloy with oxygen by titanium powder contaminated with oxygen
to aboui the required concentration. Without the indicated experiments the
recommendation of an extended use of the aforementioned bath will be pre-
mature. The titanized layer formed on 08 steel in the bath consists of a

thick 'layer of columnar grains separated from the core by a boundary line,
and'of a-thin harder external zone. The columnar grains are solid solutionz
of titanium in cO- -iron. In a part -of this zone, adjacent to the external
thiii zone, sometimes the separation of excessive titanides, pr'solpitating
during slow cooling, was observed. Data of spectral analysis, carried out
under the supervision of V.G. KoritskiT, show that the external zone contains
about 30% titanium. AcoorRIBg- to data from X-ray analysis, the external zone
of the layer on 08 grade steel is FeTiOtitanideS on 50 grade steel it is
titanium carbide, TiC. The titanized layer formed on the steel in the in-
vestigated bath has high corrosion and acid resistance.

used: a molten borax bath (60o borax and 40% B C), powdered boron carbide
and powdered boron metal. References are made to previous investigations,

temperature of 1 6100-1,3000C; boration in powder was carried out in vacuum
with 1,300-1,500 C. The microstructures of boride layers are shown (Pigure

looser affect, and boron carbide powder the least. Formation of phases
was observed which are absent in the equilibrium state (TA B ). Boration
raised the acid resistance of molybdenum in nitrohydrochlo;i2 acid 15 times
and of zirconium 12 times (in 21 hours at 200C). The resistance to Beale
formation increased 21 times for Zr, 31 times for Ta and 14 times for Ti.
The wear resistance of borated metals was dozens of times higher than that
of non-borated ones and exceeded the wear resistance of case-hardened and
quenched steel. The friction coefficient was reduced 1.5-2.0 times. There

ABSTRACT: In connection with the influence of alloying elements on the
diffusion of carbon into austenite, the authors studied the diffusion of
carbon into alloying elements cobalt and nickel in the range of 700-1000*0-
Radioactive -carbon C14 was used, and the distribution of concentration per
depth was measured. The conditions of homogenizing, to which the samples
of cobalf. and nickel were subjected, and the corresponding diffusion coef-
ficiente are tabulated. These data were used to plot the temperature do-
pendence of the diffusion eoefficients of carbon in cobalt and nickel. The
values of the free energy Q and pre-exponential coefficient Do obtained
from these plats differ from those given in the literaturet and the authors
defend their results by-pointing out the improvements involved In their
approach to the problem. Origs art. has: 4--figures, 3 formulas, and 1 table. [JPRS1

(Philos. Hag., 8, no. 86, 1963) theory of the electron structure of transition metals

number of d-alectrons per atom is Pu6 and that formation of solid compounds with ele-

ABSTRACT: Carboantimonizing of type 20 jsteel and Amco iron was studied and compared
with the more typical Femetizing process. All samples were treated in a Bandyuzhskiy
carbonizer at 9500C for 6 hrs. A mixture of 10% Na2C03 and 0.75% Sb203 was added for
carboantimonizing; 10% Na2CO3 was added for cemetizing. Microstructures showed a
light-etching layer in the carboantimonized samples which was harder and thinner than
the cemetized layer. The microthermal emf method developed at the Moscow Institute of
Steel and Alloys was used to study the diffusion layers.-IAntimony decreased the elec-1
tronegativity of microthermal emf and above 2.7% Sb, the m-icrothermal emf became more
positive (F=0.7 v/OC at 3.25% Sb). Changes in microthernal emf are given as functions
of layer thicknesses for cementing and carboantimonizing, the latter with 0.75% and
2.5% Sb203 added to the carbonizer. The Sb content of the layer was greater for 2.5%

Sb203 additions. The drop in microthermal emf from the periphery to the center ir i-
cated a decrease in Sb and C content; this was confirmed by microprobe analysis./The
Fe distribution rose from 10% at the surface to 100% at 120 U. After water quenching
from 8500C, the carboantimonized surface layers reached a Shore hardness of 1000 HV,
which was 100-200 Hv higher than for cemented layers. This was attributed to the ~
presence of FeSb and FeSb2 phases, confirmed by x-ray powder analysis. Calculated qell
volumes of both phases were 7-10% lower than the equilibrium values, due to the supMr-
saturation of Sb in the phases formed by diffusion. No preferred orientation was 1 *
found in the diffusion surfaces since no preferential diffusion path existed for S~i

ABSTRACT: The authors plated the surfaces of Armco iron specimens with a 70-100 ij
thick layer of nickel and cobalt. These specimens were tested for 1-6 hours at 9500C
in a bath composed of 60% molten borax and 40% carbide or in a melt of borax using
electrolysis. A thick boride layer was formea on all specimens which went through the
first bath under all processing conditions. The thickness of the boride layer in-
creases with time of treatment. After holding from I to 3 hours, the nickel boride
layer still consists of one zone. After 4 hdurs of holding, two zones appear in the
layer. X-ray diffraction analysis shows that these zones correspond to N13B2 and
N12B. This process Is much quicker in the case of electrolytic plating. The inter-
mediate layer cannot be observed after 3 hours of holding. A figure is given showing
the microhardness of all the phases formed in the surface layers. A study of the
boride layer shows an acicular microstructure. The length of the boride needles.

places whe~!:~~tEhe, ride needles do not penetrate the iron. Cobalt concentration ap-
proaches 100% atla given distance from the surface and then decreases sharply. This
shows that cobalt penetrates iron to a depth of 10 p which cannot be observed in
studying microstructure or microhardness. A completely different picture is seen
where the needles penetrate the entire cobalt layer. The microhardness of these need-
les varies alonj their entire length. At the surface their microhardness is from
1250-1580 kg/mm and 1680-2050 kg/mm2 at their ends. Iron content at the ends of the
needles reaches 92-88%. At the same time, cobalt content in these places is only 10-
2%. As can be seen, the boride needles which penetrate the iron mainly represent
boride with admixtures of cobalt and iron. Iron content diminishes in the boride
toward the surface, the needles consisting basically Of C02B. On the other hand,
~Fe2B is found in the specluens in the center layer. Orig. art. has: 5 figures.

see, respectively. The heterodiffusion coefficients, at temperatures investigated,
exceed the self-diffusion coefficients by approximately two orders of magnitude.
The difference in diffusion coefficients can be explained by a strong dependence of
the thermodynamic activity on the concentration of carbon in'molybdenum carbide.

ABSTRACT: A thin coating of mortar on a can.,--rete surface quickly loses water;
this fact impairs the normal course of cement hydration. To determine the
effect of quantitative water Losses on concrete strength, a number of experi-
ments, 12 times each, were stages. Plastic mortar of 1:3 composition (by
weight) was placed as a 2-cm layer e--,n the grade-200 concrete. It was found
that evaporation alone causes the mortar to lose 68% of the mix water over the
first 24 hours; capillary auction alone causes the loss of 35%; both causes, 70%.
To attain the normal humid setting of mortar, it is recommended that insulating
films be combined with q7aick-setting mortar of high-water retaining ability.

Setting Conditions of Mortar Placed on a. Concrete Surface
Experiments with the Khilok Plant cements established the effectiveness of -
introducing 8% of CaC12. Strength of mortar samples without CaCIZ, after 29
days without moistening, was found to be 9.5 kg/CM2; the same with CaC12
added, 18.6 kg/cmZ.
