Study of Electroless Plating Ni-B Composite Coating and its Properties

Huan Yang, Shi Qiu, Lu Yu, Xiao Yin, Zhenxing Liu

Abstract

The properties of Ni-B composite coating and corrosion resistance on the surface of 45 steel were investigated in this paper. An optimal component of plating solution was determined by the measurements of the stability of different component of plating solution and coating hardness as well as corrosion rate under different heat treatment temperature. The experimental results indicated that, when the heat treatment temperature was 300°C, the coating hardness reached 257HV and the corrosion rate was less than 0.15g•m-1•h-1, therefore the coating possessed high corrosion resistance.
