摘要：

In order to improve the wear resistance of pistons in drilling mud pumps, Ni-TiN composite coatings were prepared by pulse magnetic-electrodeposition method on the surface of 40Cr pistons. The plating parameters for preparing Ni-TiN composite coatings were investigated by using abrasion machine, electronic analytical balance, scanning electron microscope, and orthogonal test. The results show that the Ni-TiN composite coating deposited at magnetic intensity of 0.5 T had the minimal wear mass loss (0.72 mg). And the Ni-TiN composite coating prepared at current density of 2.2 A/dm2 and on-duty ratio of 50% had the minimal wear mass loss (0.64 mg). The optimized parameters are listed as follows: magnetic intensity 0.5 T, current density 2.2 A/dm2 and on-duty ratio 50%. © 2015, Chongqing Functional Materials Periodical Press Co. Ltd.
