The corresponding figures for electrochemically,machined specimens we're 72000 100500, and 621000 1cycles, i.e ot 28, 22, and 21.5% higber because electrochemical tically machining leavesno plas deformed surface layer, produces a better rfa e finish, and reduces tile n ber of, su c also removes the the centers of origin of microcracks, ~Electrochemical machining ., .work-hardened surface layer and residual stresses, which increases. the c clic toughness of the metal and promote extinction of resonance vibrations.
