摘要：
The paper is devoted to analysis of friction and wear of real porous sliding bearings modified with solid lubricant layers at high temperature. For this purpose, a special homemade friction tester was applied. The technology of sleeve nitriding is described. The results of the friction tests reveal about the achievement of quasi-hydrodynamic lubrication regime of powder bearings. The lowest friction coefficient is found to be f = 0.04 at 300°C. The great effect of wear rate diminishing is obtained at 300°C as interaction of microasperities is preserved at the sliding interface in quasi-hydrodynamic lubrication regime.
