Influence of the Ambient Medium in the Course of Laser Treatment on the Resistance of Titanium to Hydrogen Embrittlement

We study the kinetic parameters of the physicochemical interaction of hydrogen with annealed titanium and titanium whose surface layers are modified by laser treatment and differ, in their phase and chemical compositions, from the volume of the material. The possibilities of attainment of the maximum degree of protection of the material against hydrogen penetration and prevention of the possibility of deterioration of its operational characteristics caused by the appearance of hydrogen brittleness are determined.
