摘要：
We study the influence of temperature and time factors in the course of saturation of VT1-0, OT4, and VT14 titanium alloys from graphite in vacuum on the process of phase formation of surface layers. An increase in the temperature from 900 to 1000 degrees C and in the saturation time (to 23 h) favors the transformation of binary compounds (titanium oxide and carbide) into TiCxOy-type carbooxides, which leads to the additional hardening of surface layers. Wehave established the dependence of the composition of triple compounds on the parameters of treatment. The carbon component in carbooxides is directly proportional to the temperature and time parameters, while the oxygen component is in inverse proportion to them.
