Purpose: This paper is devoted the investigation hydrogen influence on of wear resistance high nitrogen steel (HNS) at dry and solid state lubricants assistant friction. It has been established that after hydrogenation 250 N loading rate increased by 2.9 ... 4.1 times. Microhardness hydrogenated layer was 7.6 8.2 GPa, in two After adding (GaSe)xIn1-x compounds to tribo conjugates X-ray diffraction analysis it appearance new phases which formed during friction process detected surface. Design/methodology/approach: work presents research results concerning comparative tests steels circumstances rolling conducted experiments determine tribological properties high-nitrogen under The test pieces were manufactured form rollers, rotated with a linear velocity 2.27 m/s (upper roller), 3.08 (bottom roller). Upper roller made from HNS subjected for hydrogenation. Analysis surfaces indicates complex mechanism fracture surfaces. local elements Findings: found level investigated materials Compounds realize chemisorption, tribochemical mechanisms formation thin protective (anti-wear, antifriction) layers metal Research limitations/implications: An essential problem verification obtained using standard mechanical tests, computer-based image other methods. Practical implications: observed phenomena can be regarded as basic explanation reduces plasticity characteristics Applying lubricant will allow films minimize surface wear, contribute transition wear-free mode. film barrier shear normal loads, preserving base part providing reduced Originality/value: value this permit due
