Abstract

A composite coating Inconel-625/WC on a VT6 nickel alloy is obtained by laser cladding. Studies of laser tracks of composite composition in a wide range of concentrations of the carbide phase and at different values of technological para meters of the process are carried out. Based on the results of quantitative metallographic analysis, optimal coating compositions are selected and intervals of technological parameters are established, allowing to obtain nonporous coatings with minimal penetration of the substrate and a given geometry of the cross-section of the laser track.
