Investigation on the two-stage hierarchical phase separation in the laser cladded Cu–Mn–Fe coating

A self-assembled Cu–Fe–Mn composite coating with a two-stage phase separation feature was prepared by laser cladding Cu and Mn mixed powders on a 316 L stainless steel plate. The hierarchical phase separation feature and structural evolution of the coating were systematically investigated. The microstructure of the coating exhibits by dendrites of (Fe, Mn)-rich phase and nanosized (Cu, Mn)-rich phase embedded within the matrix of the (Cu,...
