摘要： The effect of the content of nanodiamond in electrolyte and the rotational speed of the stirrer on the deposition rate of coatings, the nanodiamond content in coatings, the micro-structure and the micro-hardness of coatings was studied. A self-made pin-on-disk tribo-meter was employed to evaluate the wear resistance of prepared coatings. Results show that the thickness of composite coating decreases with the rotational speed, while the micro hardness of coatings and the content of nanodiamond in coatings increases with increasing its content in electrolyte. The wear resistance of the composite coating deposited in an electrolyte with 6g/L of nanodiamond increases by 50% in contrast with the pure Ni-P coating.
