Microstructures of Ni/WC Laser Gradient Coating on Cast Al-Si Alloy

The Ni/WC gradient coatings on cast Al Si alloy were obtained by twi remelting the preplaced alloy coatings using a 5kW CO 2 laser. The microstructures were investigated. It is shown that there is an area of Al 3Ni 2 phase in the laser gradient layer, which does not exist in the single laser alloying coating. Tungsten carbide is dissolved in the single laser alloying coating, but the tiny tungsten carbide particles can be observed in the laser gradient coating. The contents of Al and Ni from cast Al Si alloy substrate to the surface of gradient coating change more mitigratory than in the single laser alloying coating. The microhardness of laser gradient coating shows a gradual change from the substrate to the surface. However, the microhardness of laser alloying coating has the distinct difference from the substrate, there is an obvious “flat roof” area in the change curve of microhardness of single laser alloying coating.
