摘要:

采用自主研制的自动化电刷镀设备及技术制得含纳米Al₂O₃复合电刷镀层，对比研究了手动与自动刷镀层的摩擦磨损性能。通过试验得知，相对于手动刷镀层，自动化刷镀层表面更加均匀、组织更加致密、显微硬度更高。高温滑动摩擦磨损试验表明，自动化刷镀层的耐磨性能随温度的升高而降低。

Abstract:

Nano-particle reinforced nickel matrix composite coatings, n-Al₂O₃/Ni, was prepared by manual-brushplating and auto-brushplating technologies respectively. Structure and friction wear properties of the two kinds of coatings were investigated. For the auto-coating, the surface is smooth and the structure is denser, as compared with the manual-coating. Results of the friction wear testing at elevated temperature show that the wear resistance of auto-coating decreases with the increase of temperature.

Key words: auto-brush plating brush plating composite coating wear resistance at elevated temperature
