3020 Surface Modification of Various Kinds of Aluminum Alloys using YAG Laser with Powder Coating of Stainless Steel SUS316
Details
Aluminun alloy has been used to trim weight in recent years. This tend will continue in the future. However, aluminum alloy has a week point that its hardness is lower than that of iron-based metals. Also, the surface is easily damaged in comparison with iron-based metals. In this study, a modified layer was formed on the surface of various aluminum alloys by coating it with powdered SUS316 first and then by irradiating a YAG laser beam. As a result, we got the thick modified layer with high hardness on the some kinds of aluminum alloys.
