Outline of Final Research Achievements

In order to establish a laser-assisted anodizing technique for Mg-Zn-rare earth Mg/LPSO two-phase alloys, fundamental studies for development of an anodizing process and a laser-irradiation process were performed. (1) Development of novel anodizing technique using Na2SiO3-alkali-soution: Si-containing oxide films were fabricated on the surface of Mg-Zn-rare earth Mg/LPSO two-phase alloys by anodizing technique using Na2SiO3-alkali-soution. (2) Development of laser-irradiation technique: Anti-corrosive MgO surface films were fabricated on the surface of Mg-Zn-rare earth Mg/LPSO two-phase alloys by conversion technique from hydroxide to oxide using laser irradiation.
