Titanium alloy anodic oxidation coloring technique

Abstract

The invention belongs to the technical field of material surface treatment and particularly relates to a titanium alloy anodic oxidation coloring technique. According to the following technical scheme, the titanium alloy anodic oxidation coloring technique adopts an electrochemical two-electrode system, in an inorganic acid electrolyte, a direct current voltage-stabilizing power source is used forregulating and controlling the anodic oxidation voltage, and a titanium alloy is subjected to anodic oxidation coloring treatment under the indoor temperature condition. According to the titanium alloy anodic oxidation coloring technique, the titanium alloy surface with the abundant color and with a uniform colored film can be obtained, and the titanium alloy anodic oxidation coloring technique can be used in industry on a large scale.

Description

technical field

[0001] The invention belongs to the technical field of material surface treatment, and in particular relates to a titanium alloy anodic oxidation coloring process. Background technique

[0002] With its excellent properties and abundant reserves in the earth's crust, titanium alloys quickly stand out from other similar metals and shine in aerospace, shipbuilding, petrochemical and other fields. The progress and development of technology is known as the rising "third metal".

[0003] With the development of society and the enrichment of people's material life, the requirements for the appearance of titanium alloys are also getting higher and higher. The bright colors on the surface of the material can beautify the appearance of the article and improve the decorative performance through surface treatment. Anodic oxidation can make titanium alloy color anodized film have considerable economic benefits, and at the same time help to meet the market's demand for ...
