Study on the Friction Characteristics and Fatigue Life of Manganese Phosphate Coating Bearings

In this study, the tapered roller bearing was adopted to explore effect of manganese phosphate coating on friction, wear, and lifespan bearings. Line friction samples with without a were prepared. The White Light Interferometry used analyze three-dimensional morphology roughness, Optimal Schwing–Reib–Verschleiss-5 multifunctional wear tester applied obtain tribological parameters before after application coating. A scanning electron microscopy energy dispersive spectrometry characterize microstructure element composition worn surfaces influence contact stress contrasted examined by establishing finite model bearing. Finally, life test bearings performed results demonstrate that enhances resistance, lowers stress, reduces coefficient friction. fatigue can be significantly extended This is new method improve service
