摘要：
Effects of anodization by using a phosphate solution and via laser irradiation on the adhesive properties of an AZ91D magnesium alloy were evaluated to produce multi-materials for the purpose of fabrication of the lightening materials. AZ91D sheets were anodized, and then post-treatment was carried out by dipping the sheets in nitric acid solution to improve the adhesive property. The anodized film suppressed the reflection of laser beam and improves laser workability. It was possible to obtain a joining strength of more than 10 MPa by drilling the AZ91D sheets treated with anodization by optimal laser irradiation. Furthermore, the anodization in phosphate solution modifies the surface of the magnesium alloy to an inactive state, thus suppressing the deterioration of adhesiveness due to oxidation that occurs in the untreated material. © 2021 Japan Institute of Light Metals.
