Traditionally, there are several kinds of method for restraining wear. Usually, it includes the choice of the best operating conditions, the surface coating, the surface heat treatment, and the choice of the best lubricants. Among these methods, only the choice of the best lubricants has the mendable process of chemical element for worn surface, others do not have the mendable process. Consequently, this project proposes a method of continuous tribo-plating, and takes preliminary experiments by using SUJ2 ball specimen and S45C disk specimen to investigate the effects of rotational speed, anode¡¦s density of current, and specimen¡¦s surface roughness on the coating growing rate and the coefficient of friction.
Results show that the coating growing rate increases with increasing rotational speed and anode¡¦s density of current, but it doesn¡¦t be influenced by surface roughness. According to the experimental results, it is found that the frictional coefficient in order is uncoated specimen, coated specimen, and continuous coated specimen. Furthermore, at continuous tribo-plating test, specimen whose surface roughness is rough has lower frictional coefficient. According to the analyses of surface pattern and composition, specimen whose surface roughness is rough remains a lot of piece-like coating film on the surface, and this residual film provides a good effect of lubrication. The result of this project proves that continuous tribo-plating not only reduces frictional loss but also has the mendable process of worn surface.
