为提高普通镀铁层的硬度和耐磨性，扩大其在工业生产中的应用范围，进行了铁基复合镀层的制备与性能研究. 通过球磨法制备了SiC颗粒(粒径为100~200 nm)，向镀铁液中添加SiC颗粒并采用电沉积的方式制备铁基SiC复合镀层. 利用显微硬度仪、扫描电子显微镜（SEM）、能谱仪（EDS）、摩擦磨损试验机等对复合镀层的显微硬度、形貌结构、元素成分和摩擦学性能进行测试. 结果表明:复合镀层的硬度与普通镀铁层相比显著提高，稳压电压为6 V时复合镀层的显微硬度最大；复合镀层表面微裂纹呈网状结构，截面微裂纹呈短条状结构；镀层中加入SiC颗粒可阻止裂纹的扩展，减小摩擦系数，提高镀层的耐磨性能.

To improve the hardness and wear resistance of normal iron plating coating, and expend its range of application, the composite iron plating coating was developed and studied. The SiC powder (100~200 nm) was produced by using ball-milling method, then mixed in the iron plating bath to produce composite coatings through electro-deposition process. The hardness, morphology, chemical composition and tribology performance were studied by using micro-hardness tester, scanning electron microscope (SEM), energy disperse spectroscopy (EDS) and friction wear unit respectively. Results show that the micro-hardness of the composite coating is higher than classic iron plating, and reached the peak at a voltage 6 V; the surface micro-cracks appear as net structure on the surface and as short strip structure on the cross profile. The micro-nano SiC particles can prevent the propagation of the micro-cracks, reduce the friction coefficient and improve the wear-resistance properties of the coating.
Key words： SiC; composite plating coating; micro-hardnes; morphology; tribology performance
