As a new type of high-performance multi-primary alloy series, high-entropy alloy has broken through the traditional alloy category in terms of alloy principle, electronic theory and physical properties, and has the advantages of element addition and controllability of material physical properties. This study evaluates the technological design and physical innovation of high- entropy alloy preparation, focuses on laser cladding and orthogonal experiments for FeNiMoCoCrTi high entropy alloys. The corresponding solutions are proposed to deal with the limitations of the development of high entropy alloys and laser cladding technology, which provides guiding significance for the development of the application field, the research direction of laboratory and industrial production.

Key words: fiber laser, laser cladding, high entropy alloy, preparation process, process design, orthogonal test, research evaluation, robotization
