一种铝合金表面减缓液态金属腐蚀的保护膜及其制备方法
摘要：
本发明涉及一种铝合金表面减缓液态金属腐蚀的保护膜及其制备方法。本发明研究发现，钼酸盐与钨酸盐在对抗由液态金属在铝合金表面造成的腐蚀方面具有很好的协同作用，进而提出一种成分包括钨酸盐、钼酸盐、氟化物和氧化剂的处理液，其处理所得膜层性能优良，可以作为铝合金表面防止液态金属腐蚀的保护膜。所得膜层对液态金属腐蚀具有良好的减缓作用，且转化处理工艺简单，处理温度低，是针对液态金属腐蚀的优良防护膜，具有良好使用前景。
摘要（英）：

The invention relates to a protective film for slowing the corrosion of liquid metal on the surface of an aluminum alloy and a preparation method of the protective film. According to the research, molybdate and tungstate play a good synergistic role in combating the corrosion caused by liquid metal on the surface of the aluminum alloy, then treatment solution with the components including tungstate, molybdate, fluoride and oxidizer is put forward, the film layer obtained by processing has excellent properties and can be used as the protective film to prevent the corrosion of the liquid metal on the surface of the aluminum alloy. The obtained film layer has a good slowing effect on the corrosion of the liquid metal, the conversion process is simple in process, the treatment temperature is low, and the protective film is the excellent protective film for the liquid metal corrosion and has a good prospect of use.
