Outline of Final Research Achievements

In the present study, to improve the surface characteristics of magnesium alloy, the formation of an Fe-Al intermetallic compound film on magnesium alloy by compound treatment combining shot lining method and heat treatment was mainly investigated. Shot peening was performed with a centrifugal-type machine using cast steel ball. The lined sheet is aluminum foil with pure iron powders, and the workpiece was the commercial magnesium alloys. The lined workpieces are heat treated by laser in air. The iron powders and pure aluminium foils were successfully bonded to the surface of the magnesium alloy workpieces by the hit of many shots. The Fe-Al intermetallic compound that is a functional film can be formed by the laser heating treatment. It was confirmed that the present method could be used for the formation of functional films on the magnesium alloy.
