Research Progress in Laser Clad Nickel-Based Alloy Coatings

Abstract

Laser cladding, as a newly developed rapid solidification technique, is to cover a particular part of the substrate with another material that has superior properties, producing a metallurgical bond between the two materials with minimal dilution of the clad layer by the substrate. In this paper, the research progress in laser clad nickel based alloys is reviewed. The microstructures and wear resistance of the coatings are introduced, the main problems and some solutions of the laser cladding are analysized, and the development tendency and application prospect of laser cladding is also pointed out.
