Purpose: Investigations include results of research opportunities of improving the quality of open toothed wheels using advanced technologies of surface by ion nitriding in hydrogen-saturating media and subsequent heat treatment with the creation of the material in the surface layer of optimal residual compressive stresses. Design/methodology/approach: Researches on high-cycle bending fatigue were performed on the smooth cylindrical samples with a diameter of 5 mm using IMA-5 engine in pure bending with rotation (50 Hz) in the 3% NaCl solution and midair. Findings: The analysis of the operating conditions and the stress-strain state of open toothed weels showed that different portions of the surface of the teeth take different in size and type of stress. The most dangerous areas of the surface have a leg and depression between the teeth. Practical implications: Experience of operating gears indicates that the vast majority of failing of open gears occurs as a result of breakage of teeth from bending. Currently, there are many ways to improve the wear resistance and durability of the gears, but the problem is not solved until the end and it is urgent. Originality/value: In order to improving the quality of open toothed wheels by hardening the surface of the toothed wheels and especially in hazardous areas due to the deposition of hardening coatings with a gradient structure in depth, authors create a surface layer of residual compressive stress with optimal value and strengthening the core of the toothed wheel.
