Abstract

The present work is to develop a wear resistant coating on the surface of hypereutectic Al-Si alloy. By using our newly developed sol enhanced electroplating method, Ni-TiO₂ composite coating has been deposited on Al-Si alloy samples. The microstructure and property of the surface coating were analysed. The results show that, compared with the traditional Ni coating, the microhardness of the sol enhanced Ni-TiO₂ coating was significantly increased by ∼30%. Meanwhile, the corrosion property was also improved. The result indicates that this newly developed Ni-TiO₂ coating can provide surface protection and broaden the applications of hypereutectic Al-Si alloy.
