| Outline of Final Research Achievements |
The purpose of this study was (1) developing of forming technology for anti-corrosive film on flame-retardant Mg alloy by steam coating, (2) investigation of film formation mechanism and (3) evaluation of corrosion resistance of flame-retardant Mg alloy substrate with the film by corrosion promotion test. As a result of the research, it was revealed that the film was composed of Mg(OH)2: magnesium hydroxide, Mg-Al LDH: layered double hydroxide, and AlO(OH): boehmite. In addition, the corrosion promotion test clarified that the chemical reaction between the film component and the corrosion promoting ions produced the additional production and the Mg alloy substrate was hardly corroded. Therefore, the steam coating can improve corrosion resistance of flame-retardant Mg alloy.
