Abstract
A wear-resistant member production method includes: forming a clad layer by moving, relative to a substrate while feeding cladding powder onto the substrate and melting it using a local heating device; and cutting the clad layer. The cladding powder includes matrix powder containing a copper-based alloy, and hard powder including, as a hard phase, a silicide containing one or more elements selected from Cr, Fe, Co, Ni, and Cu, and one or more elements selected from Mo, W, and Nb. The hard powder includes first hard powder and second hard powder. The second hard powder is fed, separately from the first hard powder, to a melt pool formed by melting the first hard powder and the matrix powder, such that at least part of the second hard powder remains unmelted within the clad layer.
