| Abstract: |
| Objective To optimize the brush plating technology for the preparation of Ni-Mo alloy coating. Methods Based on orthogonal experiments, Ni-Mo coatings under various conditions were obtained by changing two process parameters, operating voltage and electrode relative speed. The surface morphology and microhardness of Ni-Mo alloy plating layers were studied using metalloscope and microhardness tester. Results The optimal parameters of brush plating Ni-Mo alloy were an operating voltage of 14 V and an electrode relative speed of 11. 3 m / min. The surface of the coating was bright and dense, and the microhardness value was 503. 90HV. Conclusion The research indicated that increasing electrode relative speed or operating voltage could effectively change the deposition rate, surface morphology and microhardness of Ni-Mo alloy coating. |
