Abstract
In this study, manganese phosphate conversion coatings of different thicknesses are prepared on the AISI 52100 steel surface. The tribological properties of the coatings are investigated using an SRV-V multifunctional tribometer, and the microstructure and interfacial components are analyzed through scanning electron microscopy and energy-dispersive X-ray spectroscopy. The results show that the friction coefficients of Mn–P[B] and Mn–P[H] coatings are reduced by 6% and 15%, respectively. Moreover, the EP load resistance is improved by 37% with low-viscosity lubrication oil. Under a high load, the Mn–P coatings may affect the wear mechanism of matching steel surfaces and reduce their degree of wear. The wear surface is smooth and has several uniform oil-storage holes, which are crucial to oil film formation and sustained wear resistance.
