Abstract

Aluminum-bronze was surfacing on low carbon steel in different surfacing conditions by using reverse polarity weak plasma arc. The microstructure of surfacing layer has been studied by means of optical metallograghy and X-ray diffraction. The behavior of electrochemical corrosion in PH=8.0, 3.5% NaCl solution has been studied by using the Tafel polarization method. The results show that the corrosion of al-bronze surfacing layer performs best in 3.5% NaCl solution, when surfacing current is 90A, the al-bronze surfacing layer obtains the best corrosion resistance. Then, with the increasing of surfacing current, the corrosion resistance of surfacing layer is getting worse. The microstructure is compose of () phase and -phase. The () phase suffers a dealminization preferentially, -phase has the best corrosion resistance.
