| 摘要: |
| 电镀技术常用来对已破损的零件进行修复与再制造，然而其耐磨性及耐腐蚀性能需要进一步改善。在电镀技术的基础上向镀液中添加不同浓度的 CeCl3 化合物(0、0.5、1、1.5 g / L)制备出复合镀层以探究其对电镀层性能的影响。结果表明： 在镀液中添加 CeCl3 化合物会使复合镀层中铁晶粒呈现较好的择优取向性；随着镀液中 CeCl3 化合物浓度的逐渐提升，复合镀层的显微硬度、耐磨性、耐腐蚀性均呈现出先提高后减弱的状态；当镀液中 CeCl3 化合物浓度为 0.5g / L 时，复合镀层的表面结构更为均匀、镀层中铁晶粒的排列更加致密，其显微硬度达到 611.4 HV，具有最佳的耐磨性和耐腐蚀性能。研究成果表明镀液中添加稀土 CeCl3 化合物可以大幅度提高镀层的耐腐蚀性，并在一定程度上提高镀层的耐磨性，可为实际生产中提高镀铁层的耐磨性及耐腐蚀性能提供理论指导。 |

| Abstract: |
| Electroplating technology is often used to repair and remanufacture damaged parts, but the wear resistance and corrosion resistance need to be further improved. On the basis of electroplating technology, different concentrations of CeCl3 compounds (0, 0.5, 1, 1.5 g / L) are added to the plating solution to prepare composite coatings to explore their effects on the performance of electroplating coatings. The results show that the addition of CeCl3 compound in the plating solution will make the iron grains in the composite coating show better preferred orientation; with the gradual increase of the CeCl3 compound concentration in the plating solution, the microhardness, wear resistance and corrosion resistance of the composite coating are improved. When the concentration of CeCl3 compound in the plating solution is 0.5 g / L, the surface structure of the composite coating is more uniform, the arrangement of iron grains in the coating is more dense, and its microhardness reaches 611.4 HV, it has the best wear and corrosion resistance. The research results show that the addition of rare earth CeCl3 compounds in the plating solution can greatly improve the corrosion resistance of the coating and improve the wear resistance of the coating to a certain extent, which provides theoretical guidance for improving the wear resistance and corrosion resistance of the iron coating in actual production. |
