SURFACE-TREATED METAL SUBSTRATE MATERIAL AND METAL-RESIN COMPOSITE AND MANUFACTURING METHOD AND APPLICATION THEREOF, AND ELECTRONIC PRODUCT OUTER SHELL AND MANUFACTURING METHOD THEREOF

摘要

A surface-treated metal substrate material and manufacturing method thereof, the metal being aluminium or aluminium alloy, said metal substrate material comprising a metal substrate and a micro-arc oxidised film layer attached to at least part of the surface of the metal substrate, first etched holes being distributed on the surface of the micro-arc oxidised film layer. A metal-resin composite, the metal being aluminium or aluminium alloy, said composite comprising a metal substrate material and a resin layer (2), the metal substrate material being the surface-treated metal substrate material, and the resin layer (2) being attached to at least part of the surface of the metal substrate, part of the resin in the resin layer extending downwards and filling the etched holes of the metal substrate material. The metal-resin composite meets the demands of applications having high stability demands.
