Abstract:
Nanoparticle reinforced nickel matrix composite coating, n-Al2O3/Ni, was prepared by
manual brush-plating and auto brush-plating technologies. For the auto-coating, the surface was smooth and made up of large quantity spheroid grain. The observed auto-coating’s structure was
dense. Compared with the auto-coating, the manual-coating’s surface was coarser, the grains that form the surface were not spheroid but anomalistic and similar to cauliflower. The structure of
manual-coating was sparser than the auto-coating’s. And the test found that the auto-coating’s micro-hardness improves 8% than the manual-coating’s. Results of the friction wear testing at
elevated temperature showed that the wear resistance of auto-coating decreases while the temperature goes higher. It was concluded that during the process of auto-coating, with the help of computer, the
speed, pressure and flow brush liquid was stable. While during the manual process the parameters were not controlled so that the quality of the coating was influenced. The other advantage of the
auto-coating was set worker free from the front line, decrease harm to worker, provide comfortable working condition, and keep the coating’s quality on a high level, can be adapted to large-scale
popularization and application.
