Effect of Double-layer Precoating on the Laser Cladding Ceramal Layer
The ceramal layer on the surface of mild steel was cladded by using a double-layer precoating method. The composition, microstructure, and hardness of the ceramal layer were analysed with the help of EPMA, XRD and a microhardness measuring instrument. The results show that a more uniform microstructure and higher hardness were obtained in the ceramal layer, and there are no porosities and cracks in it.
