SURFACE-MODIFIED ALUMINUM ALLOY SUBSTRATE STRUCTURE

Abstract: a surface-modified aluminum alloy substrate structure includes a 6000-series aluminum alloy substrate, a diffusion buffer layer, and a meltable metallic layer. the diffusion buffer layer is formed on the 6000-series aluminum alloy substrate for buffering magnesium in the 6000-series aluminum alloy substrate from diffusing to a meltable metallic layer. the meltable metallic layer is formed on the diffusion buffer layer for being melted in a subsequent process.
