在紫铜渗铝的基础上,同时渗入比铜和铝熔点高、比铜溶解度小的铁元素,进行固溶处理。用扫描电子显微镜、能谱仪和显微硬度计测试了渗层的组织、成分和显微硬度,用X射线衍射仪分析了物相、用动载磨料磨损试验机进行了耐磨试验、在高温箱式电阻炉中进行了耐热性试验。结果表明,Fe可以细化α+γ2组织,使片间距小、片短、更致密,抗氧化和耐磨性好于单一渗铝组织。 On the basis of copper aluminizing, while infiltrating than the high melting point of copper and aluminum, copper solubility than the small iron, for solution treatment. The microstructure, composition and microhardness of the layer were tested by scanning electron microscopy, energy dispersive spectrometer and microhardness tester. The phases were analyzed by X-ray diffractometer. Wear test was carried out with a dynamic abrasive abrasion tester. High temperature box resistance furnace heat resistance test. The results show that Fe can be refined α + γ2 organization, the film spacing is small, shorter, more dense, anti-oxidation and wear resistance than single aluminized tissue.
