Oxidation coloring method of titanium product

Abstract

The invention provides an oxidation coloring method of a titanium product. The method comprises the following steps that the titanium product surface is mechanically polished and degreased; secondly,the titanium product is placed in an electrolytic cell to be subjected to anodic oxidation treatment, an oxide thin film is generated on the titanium product surface, the titanium product is taken out, and an electrolyte on the surface is cleaned; thirdly, the titanium product is placed in a hydrogen peroxide solution to be boiled out to be subjected to oxide thin film hole sealing; secondly, anodic oxidation specially comprises the steps that a, the surface of the electrolyte is coated with a layer of electrolyte, and the titanium product is placed into the electrolyte of the electrolytic cell; b, a power source is switched on, the electrochemical reaction is carried out to generate the oxide thin film, the power source is switched off, the chemical reaction is carried out to enable smallholes to be formed in the oxide thin film, and a heating device and a stirring device are connected while the power source is switched off; c, switching on and off of the power source in the step b are repeated, and the titanium product surface is subjected to the electrochemical reaction to generate the stable oxide thin film. Method has the advantages of being simple in method, and good in titanium product surface oxide thin film uniformity.

Description

technical field [0001] The invention relates to the technical field of oxidation coloring of metal materials, in particular to a method for oxidation coloring of titanium materials. Background technique [0002] The abundance of titanium in the bottom shell is 0.56%, and the abundance of ammonia ranks ninth. my country's titanium resource reserves are quite rich. Metal titanium has two allotropic crystal forms, low temperature (<882.5 ℃) is stable as α type, close-packed hexagonal system; high temperature (>882.5 ℃) is stable as β type, body centered cubic system. [0003] Due to its excellent corrosion resistance, heat resistance and portability, titanium has been widely used in aerospace, chemical and pharmaceutical, military industry, shipbuilding and papermaking, medical equipment and other fields. After the titanium material is oxidized, a layer of oxide film will be formed on the surface of the titanium material, and the oxide film can make the titanium material...

AI Technical Summary

Problems solved by technology

[0004] At present, there are many researches on the oxidation and coloring process of titanium materials, such as atmospheric oxidation method, anodic oxidation method, chemical treatment method, etc., but in the oxidation process of titanium materials, the control of process parameters is not ideal or the ratio of oxidation reaction solution is different. , the thickness of the oxide film will be uneven, and the color will be messy after lighting, which will not only fail to achieve the effect of decoration and beautification, but will uglify the object to be decorated
