Problems solved by technology

Although the outer coating can protect the metal surface to a certain extent, after a period of use, the outer coating may still corrode and fall off, resulting in a mottled appearance of the product
Secondly, by coating the metal surface treatment of the outer coating layer, the strength between the outer coating layer and the metal surface is insufficient, which still cannot meet the requirements of abrasion resistance and scratch resistance without affecting the metal texture.

Embodiment Construction

[0022] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0023] see Figure 1 to Figure 4 , the embodiment of the present invention provides a surface treatment method for preparing the metal shell 10 and the metal shell 10 thereof. The manufactured metal casing 10 can be widely used in many fields such as automobiles, electronics, and communications, especially for products requiring high-strength and metal-like casings such as computer casings, automobiles, mobile phone casings, and the like. Described surface treatment method comprises the following steps:

[0024] Such as figure 1 and figure 2 As shown, the workpiece 12 is provided first, and then the surface of the workpiece 12 is subjected to surface pre-treatment. The surface of the workpiece 12 contains metal material to provide a metallic texture. In this embodiment, the workpiece 12 itself can be made of metal, and the material of the workpie...

Abstract

The invention provides a surface treating method of a metal housing, including: providing a workpiece having metal materials on a surface of the workpiece; carrying out a surface pretreatment on the surface of the workpiece to clean the surface, the surface pretreatment including a degreasing and washing step; and proceeding a titanizing treatment on the surface of the workpiece to form a titanizing layer on the surface of the workpiece, the titanizing layer being formed by titanizing into structural voids of the workpiece.

Description

technical field [0001] The invention relates to a casing and a surface treatment method. Background technique [0002] With the rapid development of electronic products, the use of portable electronic devices (such as mobile phones, music players, personal digital assistants) has become very common. In order to make the portable electronic device have a metal appearance, usually a metal layer is formed on the surface of the casing of the portable electronic device or a metal casing is directly used. However, when the coated metal layer or the metal outer surface of the housing is exposed to the air for a long time, it is easy to be corroded, scratched, worn and oxidized, thereby affecting the appearance of the electronic device. [0003] In order to prevent the metal surface from being corroded, scratched, worn and oxidized, the conventional technology is to apply a topcoat on the coating layer to form an outer coating to protect the metal surface. Although the outer coati...
