Blue titan-alloy microarc oxidation coloring solution and preparation method thereof

Abstract

The invention belongs to the field of metal coloring and dyeing in surface treatment technology, and particularly relates to a blue titan-alloy microarc oxidation coloring solution and a preparation method thereof, and the blue titan-alloy microarc oxidation coloring solution is used for overcoming the defects of an electrolytic coloring coating. The coloring solution comprises a microarc oxidation spark discharge introducing agent for causing microarc oxidation, a blue microarc oxidation coloring agent, a blue coasting compact accelerator, a blue microarc oxidation coating color homogenizing agent, a blue coating stabilizer and a bath solution stabilizer. The blue titan-alloy microarc oxidation coloring solution provided by the invention is applicable to microarc oxidation coloring, the resulting coating is up to 20 microns in thickness, and the coating with the thickness of 2 to 0 microns is blue as required, and the prepared coating is stable in color and luster and has the characteristic of resistance to touch and wear; the coating is compact and cannot absorb the splotch; and the coating has the excellent characteristics that no organic matter is contained, and the ultraviolet light can be resisted for a long duration. The coating is at temperature below 600 DEG C and is free from discoloring.

Description

technical field [0001] The invention patent belongs to the field of metal coloring and dyeing in surface treatment technology. The invention relates to a solution for directly producing a blue ceramic layer on a titanium alloy substrate through a micro-arc oxidation coloring process for titanium alloy parts. Specifically, it relates to a blue titanium alloy micro-arc oxidation coloring solution and a preparation method thereof. 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...

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.
