摘　　要：在实验室条件下通过多次实验研究了采用熔剂法进行纯铁表面热浸镀铝的工艺及低真空处理方法 ,摸索出较为合理的工艺流程及筛选出合适的助镀剂和镀铝液表面熔剂 ,并简要分析了原因 .对影响镀层的几个工艺参数 ,如浸镀时间、温度等进行分析讨论 ,利用扫描电镜对其镀层进行成分和结构分析 .同时 。The techniques of hot-dip aluminum on the surface of Fe by solvent method and the low vacuum treatment method are studied in the laboratory many times. Through the experiments the better promotion flux and processing flow are gained, and the reason is analyzed briefly. The effects of several technical parameters on the coatings such as the dipping time, and temperature are described. SEM is used to analyze the coating's elements and structures. Then a comparison is made between the untreated specimen and the treated specimen.
