METHODS FOR INCREASING WEAR RESISTANCE AND CONTACT ENDURANCE OF GEARS

The paper presents the results of experimental studies on the wear resistance and contact fatigue strength of samples made of various steels after strengthening by heat treatment and ion nitriding in hydrogen-containing and hydrogen-free environments under rolling-sliding friction conditions.The importance of the influence of the property gradient of the resulting compositions on performance characteristics is noted.Methods for improving the contact fatigue strength and wear resistance of gear wheels are proposed.The results of experimental studies of the wear resistance and contact endurance of specimens of various steels after hardening by heat treatment and ion nitriding in hydrogen and hydrogen-free environments under rolling friction with sliding are presented.The importance of the influence of the property gradient of the resulting composites on performance characteristics is noted.Methods for improving the contact endurance and wear resistance of gears are proposed.
