Article Preview

In this paper, laser cladding was deposited Co-9Al-7.5W superalloy on 304 austenite stainless steel plate and cladding layer shape, dilution, Vickers hardness, microstructure and distribution of alloying elements were investigated. It was found that laser cladding layer has the characteristics of large dilution rate, fine microstructure, narrow heat-affected zone (HAZ), narrow alloy elements segregation, high Vickers hardness, high contents of alloying elements and low contents of Fe in the cladding layers.
