Abstract Ni-diamond composite coating was prepared on 304 stainless steel substrates by electrodeposition technique. The diamond composite coating structure was optimized by adding the amount of diamond and thickening time. Grinding performance of the optimized diamond composite coating sliding against different counterparts (GCr15, SiC, 304 stainless steel) was evaluated by ball disc friction and wear tester. Results show that the diamond is uniform and dense when diamond concentration is 1.5 g/L. When the thickening time is 15 min, the embedding ratio of diamond is about 2/3, and the adhesion strength is better, which is suitable for the grinding process. The wear volume of GCr15, SiC, 304 stainless steel are decreased in turn, respectively, as follows: 0.353 76 mm³, 0.315 90 mm³, 0.194 01 mm³, and the diamond composite coating have better grinding performance for GCr15. Diamond composite coating grinding SiC, GCr15, 304 stainless steel have occurred abrasive wear, in addition, GCr15 also has a weak chemical wear, stainless steel has a serious chemical wear and adhesive wear.
