Research reveals optimized process parameters improve forming quality in high entropy alloy coatings, suggesting enhanced durability.
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 alloy powders and the parameters of the cladding process.By optimizing the key process parameters such as laser power, scanning speed and powder feeding rate, the forming quality of the clad-ding layer was significantly improved, the generation of pores, cracks and other defects was reduced, and the influence of adding Al, Nb and Ti elements on the forming quality of the alloy was further explored.
