DIE-CAST ALUMINIUM ALLOY PIECE, AND PROCESSING METHOD AND MOBILE TERMINAL THEREFOR

摘要

Provided is a method for processing a die-cast aluminium alloy piece, comprising the following steps: performing a strengthening treatment on a die-cast aluminium alloy piece body (10) using a strengthening liquid, so as to form an organosilicone hardened layer (20) on the surface of the die-cast aluminium alloy piece body (10); forming an aluminium film layer (30) on the organosilicone hardened layer (20) by means of vacuum coating; performing an anodic oxidation treatment on the aluminium film layer (30), so that a part of the aluminium film layer (30) is oxidized to form an anodic oxidation layer (40), wherein the ratio of the thickness of the anodic oxidation layer (40) to that of the aluminium film layer (30) is (1-3) : 1; and performing a hole sealing treatment on the anodic oxidation layer (40). The invention further relates to a die-cast aluminium alloy piece and a mobile terminal using the die-cast aluminium alloy piece.
