3020 SUS316粉末を用いた粉末固着法による各種Al合金の表面改質(S32-1 表面改質とトライボロジー(1),S32 表面改質とトライボロジー)

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.
