Experimental Study of Laser Cladding Ni-Based Coating Based on Response Surface Method
Source abstract
Abstract
In order to extend the service life of 45# steel and reduce production costs, coating NiCrBSi alloy powder on the surface of 45# steel can meet production requirements, avoid resource waste and achieve green manufacturing. Based on response surface method (RSM), the dilution rate, aspect ratio and contact angle were taken as the optimization goals, and the process parameters (laser power, scanning speed and powder feeding rate) were optimized and the optimal process parameters were determined. On this basis, the microstructure of Ni-based coating was characterized by the cladding experiment. The friction wear and corrosion resistance of the coating were tested, and the enhancement mechanism of the wear resistance and corrosion resistance of the coating was analyzed. The results show that the optimized coating has good corrosion resistance and wear resistance. It provides a reference for the optimization of process parameters in 45# steel repair work.
