采用空气助燃超音速火焰喷涂技术在30CrMnSi钢基体表面上制备出厚3 mm的HFe59-1-1铁黄铜涂层, 对涂层的化学成分、物相组成、显微硬度及耐磨性能进行了研究。结果表明: 制备的铁黄铜涂层呈层状结构, 晶粒细小, 致密度高, 孔隙率小于1%, 和基体结合强度高, 显微硬度为241 HV, 且表现出比同牌号铸造铁黄铜更为优良的耐磨性能。
Iron brass coating with thickness of 3 mm was prepared on the surface of 30CrMnSi steel substrate by high velocity air-fuel spray. The chemical composition, phase composition, micro-hardness and wear properties of the coating were investigated. The results show that the iron brass coating had layered structure, fine grains, high density, lower porosity of less than 1%, high bonding strength with the substrate and micro-hardness of 241 HV. It had better wear resistance than the as-cast iron brass with same grade.
