Properties of Ni-P and Ni-based Coating on Cast Iron Prepared by Electro-brush Plating
摘要
Abstract
ABSTRACT:Objective To repair the cast iron surface by electron-brush plating. Methods The Ni-P and Ni-based coatings were prepared on cast iron by electron-brush plating. The microstructure and phase composition of the coatings were observed, and prop-erties of the coatings such as coating adhesion, wear behavior and corrosion resistance were tested. Results Compact and dense Ni-P coating with even grains was obtained on the surface of the cast iron. Compared to the Ni-P coating, the Ni-based coating was loose and porous, with finer grains. The thickness of the Ni-P coating was about 0. 1 mm, which was 2 times as thick as that of the Ni-based coating after the same plating time. The adhesions of Ni-based and Ni-P coatings were 48 N and 85 N, respectively. Both the Ni-based and Ni-P coatings mainly consisted of Ni, Fe10. 8 Ni and FeNi3 phases, and contained a small amount of Cu. The wear resistance of Ni-P coating was the best with the lowest wear quantity and volume loss. The corrosion resistance of the Ni-P electro-brush coating was the best, with the highest Ecorr and lowest self-corrosion current density. Conclusion Electron-brush plating <br> could be used to repair the surface of cast iron by increasing its corrosion resistance and wear resistance, and the Ni-P electro-brush coating showed better properties.关键词
