- This work presents the results of tribological stand tests of slide bearings with pins modified with CrN and TiN coatings and pins with a TiN-steel 46Cr2 and CrN-steel 46Cr2 ,,ring" structure. The ,,rin" structure samples features materials with different tribological properties in the form of rings on the pin slide surface. Such a structure is obtained when covering the 46Cr2 steel pin base with a discrete layer of TiN or CrN, using the PVD method. The stand tests of frictional couplings have been performed for the frictional kinematic coupling pin with modified surface layer and CuPb30 and AlSn20 alloy bearing liner slice. During the tests the tribological couplings were lubricated with Castrol magnatec engine oil (5W/40). The tests were performed on a T-05 tribological tester. The test results demonstrated the tribological advantageous using the "ring" structure samples in the frictional couplings. The tests demonstrated that the friction forces and the bearing material quantity wear were the least for couplings with CrN steel, 46Cr2 and nitrogen hardening, and the largest for TiN pin couplings. Modification of the CrN pin surface layer has a beneficial impact on reducing frictional resistance, and temperature reduction in the friction area as well as reduction in bearing alloy wear.
