Abstract

Abstract Amorphous coating was successfully fabricated on low carbon steel substrates with one-step laser cladding method using CoCrNiSiBFe high-entropy alloy powder. The microstructure and high-temperature wear mechanism of the fabricated coating was investigated. The coating exhibited layered microstructure including the columnar dendrites as the bottom layer and the amorphous-matrix layer with β-Co phase as the minor phase. The content of amorphous phase in the upper surface was up to 85.1%. Different high temperature wear mechanism was exhibited by the two layers leading to a remarkable decrease of wear mass loss and thus a much better wear resistance in the amorphous layer.
