Notes:
Nanoparticle reinforced nickel matrix composite coating, n-Al2O3/Ni, was prepared bymanual brush-plating and auto brush-plating technologies. For the auto-coating, the surface wassmooth and made up of large quantity spheroid grain. The observed auto-coating’s structure wasdense. Compared with the auto-coating, the manual-coating’s surface was coarser, the grains thatform the surface were not spheroid but anomalistic and similar to cauliflower. The structure ofmanual-coating was sparser than the auto-coating’s. And the test found that the auto-coating’smicro-hardness improves 8% than the manual-coating’s. Results of the friction wear testing atelevated temperature showed that the wear resistance of auto-coating decreases while the temperaturegoes higher. It was concluded that during the process of auto-coating, with the help of computer, thespeed, pressure and flow brush liquid was stable. While during the manual process the parameterswere not controlled so that the quality of the coating was influenced. The other advantage of theauto-coating was set worker free from the front line, decrease harm to worker, provide comfortableworking condition, and keep the coating’s quality on a high level, can be adapted to large-scalepopularization and application
