Abstract

In this study, the effect of mechanical polishing of carbon steel on the tribological properties of manganese phosphate coating on carbon steel has investigated. The microstructure, surface morphology and chemical composition were analyzed by SEM, EDS, and XRD. The surface roughness test was carried out in order to calculate Rvk value by 3D laser microscopy. Also, the tribology property of manganese phosphate coating was tested by ball-on disk. In the results of EDS analysis, coating layer consists of elements such in Mn, P, Fe, and O. XRD showed that (Mn,Fe)5H2(PO4)4·4H2O in manganese phosphate coating layer was formed by the chemical reaction between manganese phosphate and elements in carbon steel. As the mechanical polishing degree increased, the friction coefficient was reduced. The rougher the mechanical polishing degree, the better corrosion resistance was obtained.
