Research status and application of the high-entropy and traditional alloys fabricated via the laser cladding

Abstract

The objective of this paper is presenting a review of high-entropy alloys and traditional alloys fabricated by laser cladding. In this paper, recent developments of different material system are summarized, and the developments in laser cladding for functional coatings with high wear resistance, good corrosion and oxidation resist-ances, and better medical biocompatibility are reviewed. By summarizing the analysis of microstructure, mechanical properties, corrosion resistance of high-entropy alloys and traditional alloys’ coating fabricated by laser cladding, it stated that laser cladding treatment can improve corrosion resistance, homogenize grain size, and increase microhardness and other properties. Laser cladding is considered as the potential method to ameliorate mechanical properties, improve microstructure and repair broken parts. Therefore, laser cladding has the successful applications in automobile and aerospace productions, and shipbuilding due to those advantages.
