Abstract
The ability of hydrogen to penetrate through the oxide film formed during air-atmosphere annealing at elevated temperatures on VT6 titanium alloy samples was studied in this paper. It was investigated that oxide film prevents the penetration of up to 0.4 wt.% hydrogen. It was shown that it is possible to change the depth of hydrogen penetration and the surface layer structure by varying the amount of added hydrogen. It was determined that the formation of a finely dispersed surface structure after the thermal hydrogen treatment allows to increase the surface hardness by 8-10 HRC, compared to the center of material.
