中文摘要：
以自制纯度超过98％（体积分数，下同）的Ti3SiC2陶瓷粉体为原料，加入分散剂和表面改性剂，制成稳定悬浮液，并加入Watts镀镍电镀液，利用磁力搅拌分散均匀，在阴极电流密度2A／dm^2～5A／dm^2下，在低碳钢基体表面成功得到Ni-Ti3SiC2减摩复合镀层。SEM观察表明，表面改性剂的加入有效地改变了粉体表面电导性质，得到致密平整的复合镀层结构。XRD及EDS分析表明：镀层中Ti3SiC2微粒含量为5％～14％（体积分数，下同）。当制备过程中以间歇式搅拌代替连续搅拌时，可得到Ti3SiC2相含量超过30％的复合镀层。复合镀层的显微硬度随微粒含量的升高而增大。
英文摘要：
Ni-Ti3SiC2 composites coating was co-deposited on a steel substrate by DC electrodeposition. 98 vol. % purity Ti3SiC2 ceramic powder pretreated with surfactant was added into a Watts＇ nickel plating bath, and stirred by magnetic stirring. Composite coating was fabricated at a cathode current density of 2 A/dm^2-5 A/dm^2. Surface patterns of the samples were observed by scaning electron microscope （SEM）. XRD and EDS were used for a study of coating structure and component. Over 30 vol.% Ti3SiC2 particle was co-deposited within nickel plating by a intermittent stirring. The micro hardness of the composites coating was also studied, which was increased with the increasing Ti3SiC2 particle content.
