In the paper there is considered a problem of wear-resistance increase in parts operating in hydrogen environment. The dependence of friction surface wear taking into account their sub-roughness and hydrogen existence is shown. A technology for a friction couple wear-resistance increase is offered including surface layer granularity decrease, the reduction of hydrogen content in an inter-grain space and the introduction in the structure of parts surface layers the elements allowing filling up an inter-grain space. The results of comparative wear tests for different technologies for wear-resistance increase are shown. It is defined that the technology offered allows increasing wear-resistance in friction surfaces in machine parts. A method for account of hydrogen existence in an inter-grain space is offered and a reasonable method for obtaining a numerical value of a factor taking into account hydrogen presence used for theoretical computations.
