颗粒增强复合镍基涂层耐磨性的研究

Wear resistance of particle-strengthende Ni-base coatings

研究了４种不同涂层的耐磨性能，并对涂层形貌、组织、硬质相等进行了分析，结果表明：Ｎｉ６０中添加价格较低的ＦｅＯ５粉末后，涂层耐蚀磨损性能得到改善；随ＷＣ含量的增加，涂层的耐冲蚀磨损的性能也得到提高；而加入硬质颗粒后，其合金粉末涂层的耐磨性却不一定提高．

Wear resistance of four kinds of coatings were investigated. Their morphologies, microstructures and strengthening phases were analyized. The results showzed that wear resistance could be improvedby adding cheap powder of FeO_5 into Ni-base coating.
