ABSTFaCT: The dependence of the power generated by a resonator u'pon the reflection
coefficient of the mirrors r is examined. The effect of r upon the pumping efficiency

ABSTRACT: 1yorganosiloxane liquiAv,1322 30C0 is prepared now in an enameled
reactor by the reaction at 95C of a mixture of organic silicon monomer with 25% solu-
tion of NaOH. A number of corrosion-resistant alloys was tested for-behavior under
reactor conditions because Soviet industry does not now produce apparatuses that are
protected by acid-resistant enamel& Samples 40 X 15 x 2 mm large) after the required
treatment, were suspended on teflon ribbons in the working reactor into gas and into
liquid phases. The.suspension was devised so that the samples neither touched each
other nob the walls of the reactor. For the alloys investigated, the corrosion ra s
at 95C in the gas and liquid phases were determined (in mm/yr) to be as follows:1

TITLE: On the Causes of a Linear Relation Between the
Thickness of the Layer and Duration of the Process
of Borating Nickel

TEXT: In an earlier paper (Ref. i Fmm, 1961, 12, 217)
the authors and I.V. Kazakov have shown that in borating nickel
a linear dependeFice was observed between the thickness of the
metal layers At expended on forming the boron film and the
time of boron deposition /'I_- for /Ae 1~~ 0.8 mm. Usually,
the curve reflecting the speed of t~ e diffusion process is a
parabola, for which the equation y = f, ^r, is valid; linear
dependence between the thickness of the layer and the time is
possible only if the forming film has mechanical defects along
-hich the diffusing substance migrates to the surface of the

base material. A photograph of a polished microsection of
a boride layer is reproduced, from which it is concluded that
the linear dependence is not due to mechanical defects of the
film since defects at a direction normal to the surface of the
specimen were not detected in the film. Comparison of the
structune of boride films on nickel and cobalt has shown that
they are qualitatively equal in spite of the fact that the
increase in thickness of the boride film obeys the parabolic
law in the case of cobalt and the linear law in the case of
nickel; Figs. 3 and 4 show the dependence of the thickness
of the borated layer n~e, mm 0as a function of time, hrs, for
a borating temperature of 900 C for nickel and cobalt,
respectively. It was established that the temperature coefficient
of the speed of borating nickel at temperatures above 900 0
was considerably higher than was anticipated on the basis of
the exponential time dependence of the diffusion coefficient.
If borating was at 1 000 0C the eutectic NiB + N:L3B2 with
a fusion temperature of 990 0C formed and the specimens

melted off. Formation of this eutectic led to thp idea that
in the case of the formation of borides being eicotIfdrmaI:-the linear
dependence between the thicXness or the borated layer and the
time at temperatures not differing greatly from the tempera-
ture of formation of the eutectic can be explained as follows.
At the surface of the nickel specimens which is subjected toborafing
there will be concentrational fluctuations; due to the exo-
thermal nature of the process this will lead to a local
increase in the temperature in the borated specimen and to
the formation of a low melting-point eutectic at these points.
The diffusion coefficient at these points will increase. . .
instantaneously and this will lead to an overall increase in
the diffusion coefficient and will result in a linear
dependence between the thickness of the layer and the borating
tim.p. Conservation of the parabolic dependence in the case of
'cobalt is obviously due to the fact that the temperature of
formation of the low melting-point eutectic Co-B, which is
1 105 OC, exceeds the borating temperature by 205 OC, whilst
in the case of nickel this temperature difference is only

900C. Thus, the heat released during borating of cobalt is,
apparently inadequate for producing a low melting-point
eutectic at the spots.where concentration fluctuations occur
and, as a result of this, the parabolic dependence Ae = f(*t)
is maintained in the case of borating cobalt undw~ the given
temperature conditions. There are It figures and 4 references:
