Abstract

The invention discloses a preparation method of a decorative ring, the decorative ring and electronic equipment, and belongs to the technical field of electronic equipment. The preparation method of the decorative ring comprises the following steps: forming a blank; performing primary anode hardening treatment on the formed blank to generate a first hardened layer on the blank; preparing a protective layer on the blank with the first hardened layer; machining a protruding part on the blank to form a ring material; carrying out secondary anode hardening treatment on the ring material so as to form a second hardened layer on the convex part; and carrying out protective layer removing treatment on the ring material with the second hardened layer to form the decoration ring, wherein the hardness of the second hardened layer is larger than that of the first hardened layer.

Description

technical field [0001] The application belongs to the technical field of electronic products, and in particular relates to a preparation method of a decorative ring, a decorative ring and an electronic device. Background technique [0002] The decorative ring of the camera on the mobile phone generally uses aluminum alloy as the body, stainless steel as the protruding and wear-resistant part, and the stainless steel and aluminum alloy are connected by bonding. This bonding method can use the high hardness of stainless steel after physical vapor deposition to ensure its wear resistance. However, the cost of this solution is very high, and the structure and process are relatively complicated, and because of the adhesive connection, the overall structural strength is low. If the integrated aluminum alloy solution is adopted, the overall strength can be improved, but the local wear resistance will be reduced. . In addition, in some related technologies, anodic oxidation is use...
