Green series titanium alloy micro-arc oxidation coloring solution and preparation method thereof

Abstract

The invention belongs to the field of metal coloring and dyeing in a surface treatment technology, and in particular, relates to a green series titanium alloy micro-arc oxidation coloring solution and a preparation method thereof, used for solving the defects of an electrolytic colored film. The coloring solution comprises a micro-arc oxidation spark discharge introducing agent for producing micro-arc oxidation, a green micro-arc oxidation coloring agent, a green film compactness accelerant, a green micro-arc oxidation film color homogenizing agent, a green film stabilizer and a bath solution stabilizer. By using the solution for micro-arc oxidation coloring, the thickness of the film can reach 22 microns, the film is green as required when the thickness is 3 to 22 microns, and the formed film is stable in color, has the characteristics of touch resistance and abrasion resistance, is compact and does not adsorb dirt. More preferably, the film does not contain organic substances, and can tolerate ultraviolet for a long term. The film does not change color at the temperature below 500 DEG C.

Description

technical field [0001] The invention belongs to the field of metal coloring and dyeing in surface treatment technology, and relates to a solution for directly producing a green ceramic layer on a titanium alloy substrate through a micro-arc oxidation coloring process for titanium alloy parts, specifically a green titanium alloy Micro-arc oxidation coloring solution and its preparation method. Background technique [0002] Metal coloring and dyeing refer to the process of making the surface of the metal itself produce a different color tone from the original and maintain the metallic luster. The currently publicly reported titanium alloy coloring technology includes electrolytic coloring technology, such as the patent CN102080247 smoke yellow titanium alloy coloring processing method, which is an electrolytic coloring technology. The film layer is an amorphous thin film, and the thickness of the film layer is less than 1 micron. The film layer is not wear-resistant, and it ...

AI Technical Summary

Problems solved by technology

The film layer is not wear-resistant, and it is easy to discolor and absorb stains when touched by hands. When the temperature is above 200°C, the film layer cannot prevent the titanium substrate from being oxidized and discolored.
