The microstructure and the wear resistance of precision nickel alloy 40KhNYu-VI used for the production of paramagnetic bearings are studied after glow discharge nitriding. It is shown that the continuous layer of CrN nitride formed under the nitriding provides substantial elevation of the wear resistance of the surface of the parts. The wear intensity after the nitriding decreases by a factor of 5 – 8, which shows the possibility of application of glow discharge nitriding to parts operating under dry and boundary friction.

精密镍合金轴承零件辉光放电渗氮后的磨损

研究了用于生产顺磁轴承的精密镍合金40KhNYu-VI在辉光放电渗氮后的显微组织和耐磨性。结果表明，在渗氮下形成的连续的 CrN 氮化物层显着提高了零件表面的耐磨性。渗氮后的磨损强度降低了 5-8 倍，这表明辉光放电渗氮应用于干摩擦和边界摩擦下的零件的可能性。
