| 摘要: |
| 为了进一步延长45钢工件的耐磨性能,减少企业维修和更换45钢类零件的成本,在传统材料45钢表面,开展了稳恒磁场辅助的电喷镀试验研究,通过配制不同ZrO2纳米颗粒质量浓度的镀液,制备了Ni-P-ZrO2镀层,利用扫描电子显微镜(SEM)、能谱分析仪(EDS)、显微硬度检测仪和共聚焦显微镜等仪器对镀层表面形貌、Zr元素含量、显微硬度以及耐磨性能进行了分析。研究发现:ZrO2纳米颗粒和稳恒磁场的加入改善了镀层表面形貌,提高了显微硬度和耐磨性能；当ZrO2纳米颗粒质量浓度达到15 g/L时,ZrO2纳米颗粒易出现团聚现象,不利于镀层表面性能的进一步提升。磁场辅助下,镀液中ZrO2纳米颗粒质量浓度为10 g/L时,得到的镀层表面更加平整、显微硬度最高达到了739.30HV,且磨痕宽度、深度以及截面面积达到最小值,分别为367.617、5.673 μm和1 288.155 μm2,镀层耐磨性能最佳。 |

| Abstract: |
| In order to further enhance the wear resistance of 45 steel workpiece and reduce maintenance and replacement costs, Ni-P-ZrO2 coatings was prepared on the surface of 45 steel with the assistance of steady magnetic field. The surface morphology, element content, microhardness, and wear resistance of the coatings were examined using scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), microhardness tester, and confocal microscope. It was found that the addition of ZrO2 nanoparticles and steady magnetic field improved the surface morphology, microhardness, and wear resistance of the coatings. However, at a concentration of ZrO2 nanoparticles in the plating solution of 15 g/L, the agglomeration of ZrO2 nanoparticles occurred, which reduced the quality of the coatings. At a particle concentration of 10 g/L, the coating prepared with the assistance of steady magnetic field possessed smoother surface, the highest microhardness of 739.30HV, and the smallest width, depth, and cross section area of the wear mark (367.617 μm,5.673 μm, and 1 288.155 μm2, respectively), suggesting the best wear resistance. |
