Research on Microstructure and Wear-Resisting Property of NiCrWMo Laser Cladding on K418

Abstract:

Laser cladding on K418 substrate using NiCrWMo powder by Nb:YAG laser was carried out for the repair of aero blades. The microstructure and microhardness of cladding layers were investigated. The result showed that using the correct nickel based alloy powder, at the craft parameter of electric current 160 A, pulse width 8mses, the frequency 4 Hz, the surface is balanced and continuous; the microstructure is close and uniformity; the cladding is well combined with the substrate without flaw; the rigidity of the cladding is higher than the substrate .
