Abstract

Titanium alloys (commercial-purity titanium VT1-0, pseudo-α-alloy OT4, and (α+β)-alloy VT14) are studied after carbooxidation from graphite by contact and noncontact methods in vacuum of 1.3 – 13 Pa at 950 and 1000°C for 5 h. The results of these modes of carbooxidizing are compared. X-ray phase, gravimetric, and x-ray diffraction analyses and hardness measurement are used to show the dependence between the distance from the graphite surface to the specimen and the intensity of carbooxidation.
