Abstract

The invention provides a method for preparing a casing, which includes the following steps: providing an aluminum substrate; performing hard anodic oxidation treatment on the aluminum substrate, forming a first aluminum oxide layer on the surface of the aluminum substrate, and the first An aluminum oxide layer has micropores, and the hard anodizing process automatically adjusts the voltage and current during the hard anodizing process; dyeing the aluminum substrate; polishing the dyed aluminum substrate, Get the shell. The casing prepared by the preparation method of the casing of the present invention has a black and bright appearance and a ceramic texture. The invention also provides a casing manufactured by the method for preparing the casing and an electronic device using the casing.

Description

technical field [0001] The invention relates to the technical field of electronic devices, in particular to a housing, a method for preparing the housing and an electronic device using the housing. Background technique [0002] At present, electronic devices such as mobile phones usually use aluminum alloy shells, and the hardness of the aluminum alloy shells is improved by anodizing the aluminum alloy shells. Since most of the housings of electronic devices are treated with anodic oxidation, the appearance of existing housings of electronic devices is seriously homogeneous, which cannot improve the brand attributes of electronic devices. Contents of the invention [0003] The main purpose of the present invention is to provide a method for preparing a casing, aiming to provide a method for preparing a casing with a black and bright appearance and a ceramic texture. [0004] In order to solve the above technical problems, the preparation method of the housing provided by ...
