颗粒增强铝基复合材料废料回收的试验研究

TRIAL STUDY ON THE RECOVERY OF PARTICLE REINFORCED ALUMINUM MATRIX COMPOSITE'S SCRAP

为了回收铝合金基体材料 ,配制了合适的混合盐熔剂 ,采用熔融盐法去除颗粒增强铝基复合材料中的增强材料。进行了金相观察和 X射线衍射分析 ,并测定基体合金的回收率 ,结果表明复合材料中的增强材料能被一定量的熔融盐去除 ,其回收利用率大约为 85 %

In order to recover aluminum from aluminum matrix composites, the appropriate compound salt was prepared and the removal behavior of reinforced materials from particle reinforced aluminum matrix composites was investigated experimentally by using molten salt process. The recovery of aluminum was measured by microscopic examination and X-ray diffraction. The results indicate that the reinforced materials can be eliminated from aluminum matrix composites by molten salt, and the recovery ratio is about 85%.
