This paper reports the problems considered regarding the hydrogen wear decrease in steel parts operating in hydrogen medium and, in particular, in hydrocarbon liquids. The comparative researches are carried out with samples after thermal treatment, high-vacuum annealing and ionic implantation and also after a combination of these methods. The structure of samples surface layer is investigated after a combined working and the values of micro-hardness of layers formed are given. The investigation of surface quality changes is carried out. The results of comparative abrasion tests of samples are presented. It is defined that after a combined working samples wear decreased. There are shown data on the hydrogen concentration in a surface layer of samples and the analysis of surface properties for hydrogen concentration and hydrogen wear intensity is carried out.
