| Abstract: | Pinhole and poor coating adhesion were obtained on Fe-based powder metallurgy articles by direct electroless Ni plating because of high porosity. The electroless Ni plating on Fe-based powder metallurgy articles was continuously carried out with pretreatments of pore sealing by immersing in zinc stearate in vacuum and ultrasonic cleaning. The results of performance examination showed that the coatings are uniform, compact and well-adhered to the substrate, and have significantly improved wear and corrosion resistance. |
