Kinetics of the processes of gas impregnation and sublimation of titanium alloys in vacuum at temperatures of 1123 and 1273/sup 0/ K
This paper studies the kinetics of the processes of interaction of titanium alloys with the residual gases of a vacuum and reveals their influence on the structure of the surface layers of titanium alloys. Aluminum, cannot sublimate since it possesses the greatest affinity for oxygen among the alloy elements, and titanium and zirconium, judging from the pressure of the staturated vapors of the pure metals and their oxides, cannot sublimate because of the low values of the parameters. An increase in temperature to 1273 degrees K does not qualitatively change the character of interaction of PT-7M, PT3V, VT6S, and OT4-1 alloys with the residual gases of the vacuum, but intensifies these processes. In VT5-1, a qualitative change in the processes as the result of activation of sublimation of tin from the alloy is observed.
