Embodiment 1

[0019] Titanium and titanium alloy anodic oxidation coloring process of the present invention, described technological process is to carry out the following steps to the titanium or titanium alloy after machining cleaning:

[0020] (1) Pretreatment, the surface of titanium or titanium alloy is subjected to light grinding and grinding treatment, and the oxide scale on the surface of titanium or titanium alloy is removed to obtain sample A of titanium or titanium alloy. The surface of sample A of titanium or titanium alloy forms a high Bright state, and the surface state is uniform, providing an excellent matrix state for the anodizing process;

[0021] (2) pickling and activation, pickling and activating treatment of titanium or titanium alloy sample A with pickling solution to obtain titanium or titanium alloy sample B, the surface of titanium or titanium alloy sample B reaches an activated state, and The high-gloss surface of sample B of titanium or titanium alloy will not be...

Embodiment 2

[0028] Titanium and titanium alloy anodic oxidation coloring process of the present invention, described technological process is to carry out the following steps to the titanium or titanium alloy after machining cleaning:

[0029] (1) Pretreatment, the surface of titanium or titanium alloy is subjected to light grinding and grinding treatment, and the oxide skin on the surface of titanium or titanium alloy is removed to obtain sample A of titanium or titanium alloy.

Abstract

The invention discloses an anodic oxidation coloring technology for titanium and titanium alloy. According to the technological process, the machined and cleaned titanium or titanium alloy is subjected to the following steps that (1) pretreatment is conducted, specifically, light grinding treatment is conducted on the surface of the titanium or the titanium alloy, so that a sample A of the titanium or the titanium alloy is obtained; (2) pickling activation is conducted, specifically, the sample A of the titanium or the titanium alloy is subjected to pickling activation treatment through a pickling solution, and a sample B of the titanium or the titanium alloy is obtained; and (3) anodic oxidation is conducted, specifically, the sample B of the titanium or the titanium alloy is subjected to anodic oxidation treatment through electrolyte, and a product C of the titanium or the titanium alloy is obtained and has a high-brightness oxidation film with different colors. According to the anodic oxidation coloring technology, the treatment procedure is short, the surface of the titanium or the titanium alloy is high in quality and glossy, and on the basis that the basic performance of an original colorful oxidation film is maintained, the product is made to be more beautiful.

Description

technical field [0001] The invention relates to the technical field of metal surface treatment, in particular to a titanium and titanium alloy anodic oxidation coloring process. Background technique [0002] Titanium is a silver-white transition metal, characterized by light weight, high strength, metallic luster, and good corrosion resistance, mainly showing resistance to moisture and chlorine gas corrosion. Due to its stable chemical properties, it has the advantages of good high temperature resistance, low temperature resistance, strong acid resistance, strong alkali resistance, high strength and low density. [0003] Titanium alloys are alloys based on titanium and added with other elements. Titanium alloy also has the advantages of high strength, low density, good mechanical properties, good toughness and corrosion resistance. Titanium alloys are widely used in various fields because of their high strength, good corrosion resistance, and high heat resistance. [0004...
