Influence of nitriding of the surface of steels on their tribotechnical properties and durability of bearings

The article describes a method for determining the friction coefficient of bearing materials. The testing takes into account the features of loading and motion. The results of experimental determination of friction coefficients for nitrided surfaces of steels used in bearings are shown. A comparison of friction coefficients of bearing materials is given, where the effect of nitriding of the surfaces of steel balls is shown. Recommendations are given for the application of antifriction coating in the form of nitriding. The results of comparative tests of bearing durability with nitrided and non-nitrided working surfaces are given. It is shown that nitriding of the working surfaces of bearings increases their durability.
