利用浸渍法在铝金属基复合材料Al6 0 6 1/SiCp表面获得了混合稀土转化膜。利用湿热试验、盐水浸渍试验和电化学测试方法 ,评价了膜的耐蚀性能。用扫描电镜观察了膜的表观形貌 ,利用X射线衍射仪研究了膜的微观形态 ,膜是以非晶态形式存在的
A mixed rare earth conversion coating was obtained on the surface of Al6 0 6 1 / SiCp by impregnation method. The corrosion resistance of the film was evaluated by wet heat test, brine immersion test and electrochemical test. The morphology of the film was observed by scanning electron microscopy. The microstructure of the film was studied by X-ray diffractometer. The film was amorphous
