Abstract

This study is based on the CoCrFeNi alloy system. By adding alloying elements such as Al, Nb and Ti and using laser cladding technology for preparation, it aims to optimize the composition design of the alloy powder and the cladding process parameters. This experiment conducted an optimization study on the process parameters of laser cladding. The experimental results show that the appropriate addition of Al, Nb and Ti elements can effectively enhance its me-chanical properties. This research provides important theoretical basis and practical guidance for the design and development of high-performance CoCrFeNi series alloys and the engineering application of laser cladding tech-nology.
