Problems solved by technology

Anodic oxidation is to put the formed and cleaned titanium material into the oxidation coloring solution, pass direct current, and make the titanium material colored through the electrode oxidation reaction. This method has the disadvantages of many process steps and many types of chemicals used. In addition, , the treatment efficiency of anodic oxidation coloring is low, and it is only suitable for small batch processing
Compared with anodic oxidation coloring, the PVD method improves the efficiency to a certain extent and reduces the environmental pollution of the coloring process, but it still needs to be applied separately after the titanium material is processed, and the process is still long. In addition, PVD The adhesion between the coating and the titanium substrate also needs to be improved
[0005] In summary, the existing titanium surface coloring process has problems such as a long process and insufficient bonding of the coloring layer and the base material layer.

Abstract

The invention discloses a coloring process of a cold-rolled titanium material, and belongs to the technical field of titanium material machining. The coloring process of the cold-rolled titanium material comprises the step that in the mixed atmosphere of nitrogen and inert gas, the cold-rolled titanium material subjected to degreasing treatment is subjected to annealing treatment, and then the titanium material with the colored surface is obtained. According to the coloring process, surface coloring treatment can be conducted on the cold-rolled titanium material while annealing treatment is conducted on the cold-rolled titanium material, the technological process is shortened, and the treatment efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of titanium material processing, and in particular relates to a coloring process of cold-rolled titanium material. Background technique [0002] Due to its excellent corrosion resistance and high-end metallic luster, the application of titanium in the field of architectural decoration has gradually emerged in recent years, such as the Hangzhou Grand Theater, the Marquess de Riscal Hotel in Spain, the Kyushu Petroleum Stadium in Japan, or the use of titanium Curtain walls or tiles made of titanium. [0003] Titanium materials used in industry usually do not need to undergo special coloring treatment, that is, they can directly display the metal color of titanium; while in some personalized designs, titanium materials are required to show special color appearance, that is, it needs to be subjected to various treatments. Coloring treatment, for example, the titanium curtain wall set in the Marques de Riscal Ho...
