Embodiment Construction

[0028] Please refer to figure 1 , is a schematic diagram of the method for forming a two-color anode titanium film of the present invention. The method for forming a two-color anodic titanium film of the present invention can be divided into a preliminary process A, a first anodizing process B1, a mask removal process A2, and a second anodizing process B2. Each flow will be described below.

[0029] [Preparation Process A]

[0030] Please refer to figure 1 and figure 2 , figure 2 A schematic diagram of the steps of the preparatory process A of the present invention is shown. In step A11 , a base material 102 is provided. The base material 102 is mainly made of metal, which may be a metal shell, such as aluminum, aluminum alloy, stainless steel or magnesium alloy shell, or even a non-metal shell.

[0031] Next to step A12 , as for the part of the metal casing, the base material 102 needs to be cleaned according to the situation to make it suitable for anodic treatment. ...

Abstract

The invention provides a bicolor anode titanium film forming method and a product. The method comprises the following steps: in a preparation procedure, firstly, providing a base material and cleaning the base material, depositing a titanium film on the base material, and forming a shielding cover on the base material; in a primary anode oxidization procedure, immersing the base material with the titanium film as an anode in electrolyte, and filling a first direct current voltage to oxidize the surface of the titanium film and generate a first thin titanium oxide layer on the base material; then, removing the shielding cover, and performing a secondary anode oxidization procedure, wherein the secondary anode oxidization procedure comprises: immersing the base material as the anode in the electrolyte; filling a second direct current voltage lower than the first direct current voltage to oxidize the surface of the titanium film and generate a second thin titanium oxide layer on the base material; and finally, cleaning the base material. The anode oxidization is performed by two different voltages to easily form more than two metallic lustres on a metal shell.

Description

technical field [0001] The invention relates to a method for forming a two-color anode titanium film and its products, in particular to a method for forming a titanium oxide film on the surface of a substrate to make the substrate have two or more metallic luster colors, and using the method for forming a two-color anode titanium film. Products made by the method. Background technique [0002] Nowadays, portable electronic products are very popular, such as mobile phones, personal digital assistants, computers and so on. Consumers pay more and more attention to their appearance, so the shells of various electronic products usually have bright surfaces, especially metal surfaces, which are usually treated with various procedures to make them have an attractive smooth surface and gloss. [0003] In order to color the surface of the housing, currently known techniques include the use of anodic oxidation to form a thin layer of titanium oxide on the metal surface to produce col...
