Abstract

Al-Mg films were prepared onto steel sheet according to deposition condition by eco-friendly electron beam vacuum evaporation method. The influence of Al-Mg films on corrosion resistance was evaluated by salt spray test and electrochemical method etc.. From the experimented results, it was found that the Al-Mg films which showed good corrosion resistance tend to have fine structure with homogenious composition distribution. In addition, it was shown that the property of coating films can be improve by controlling thickness ratio and uniform distribution of intermetallic compounds in Al-Mg films.
