Embodiment Construction

[0013] see figure 1 As shown, the casing 10 of the preferred embodiment of the present invention includes a metal base 11 and a micro-arc oxidation film layer 13 formed on the metal base 11 .

[0014] The material of the metal base 11 can be any one of aluminum, aluminum alloy, magnesium, magnesium alloy, titanium and titanium alloy.

[0015] The micro-arc oxidation film layer 13 includes a first surface 131 and a second surface 133 opposite to the first surface 131 , and the first surface 131 is combined with the metal base 11 . Part or all of the second surface 133 exhibits a mirror effect, which can be formed by polishing the second surface 133 . The polishing method can be mechanical polishing. A groove 15 is formed in the region where the second surface 133 presents a mirror effect, and the groove 15 is in the shape of a pattern, and the pattern can be a product's trademark or symbolic pattern, or other patterns with decorative effects. The groove 15 can be formed by l...

Abstract

The invention provides a housing. The housing comprises a metal substrate and a micro-arc oxidation film layer formed on the metal substrate, wherein a region with mirror surface effect is formed on the surface of the micro-arc oxidation film layer; and a groove is etched in the region having the mirror surface effect. A method for making the housing comprises the following steps of: providing the metal substrate; performing micro-arc oxidation treatment on the metal substrate so as to form the micro-arc oxidation film layer thereon; polishing the micro-arc oxidation film layer; and etching the groove on the polished micro-arc oxidation film layer.

Description

technical field [0001] The invention relates to a casing and a manufacturing method thereof. Background technique [0002] Conventionally, the surface of the metal casing of the portable electronic device is usually surface-treated to form an oxide film layer with high hardness and strong corrosion resistance on the surface. Micro-arc oxidation technology (also known as plasma oxidation, anode spark deposition, spark discharge anode deposition and surface ceramicization, etc.) is a technology that directly grows an oxide film on the metal surface in situ. The oxide film layer formed on the surface of the metal shell by this technology has good wear resistance, strong corrosion resistance and thermal shock resistance, and good insulation performance. However, the oxide film layer has a single matte matte appearance, single visual effect, and weak decoration, so it is difficult to increase the added value of the product and attract the attention of consumers. Contents of th...
