“…On the other hand, WC decomposes when heated and reacts with the surrounding metal solution, promoting the growth of nuclei and accelerating the formation and nucleation of heterogeneous crystals. At the same time, unmelted WC particles can hinder the growth of dendrites and alter the formation of growth [ 22 ]. Therefore, with increasingly uniform distribution of WC particles, the grain can be refined to significantly improve the microhardness.…”

Ni60A/WC composite coating is prepared on 45 steel substrate by alternating-magnetic-field-assisted laser cladding. We compare the effects of different magnetic field intensity on WC particle distribution, microstructure, phase composition, microhardness and wear; in addition, the mechanism of alternating magnetic fields on cladding layers is briefly analyzed. The results show that an alternating magnetic field can significantly homogenize the distribution of WC particles. WC particles at the bottom are stirred and dispersed to the middle and upper area of the laser pool. The distribution of WC in the bottom region 6 of the coating decreases from 19.1% to 10%, the distribution of WC in the bottom region 5 decreases from 46.46% to 33.3%, the WC distribution in the top region 1 of the coating increases from 0 to 7.7% and the WC distribution in the top region 2 of the coating increases from 8.08% to 12.2%. The stirring of alternating magnetic fields strengthens the solute convection in the laser pool, refines the snowflake-shaped carbide hard phase and improves the coating microhardness and wear property, and adhesive wear and abrasive wear decrease gradually with increasing magnetic field strength.

“…Liu et al [7] prepared Ni60-Cu composite coatings with different Cu content on the surface of 45# steel, and studied the effects of Cu content on microhardness and tribologi-cal behavior. The results show that the Ni60-5%Cu coating shows the best friction resistance at 600 • C. Zhou et al [8] prepared Ni60 coating on 45# steel surface with the assis-tance of magnetic, ultrasonic and electric field. The results show that the microstructure of the Ni-based coatings prepared under the influence of multiple physical fields is refined, the distribution of elements is uniform.…”

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.
