METHOD FOR FORMING COATING HAVING CARBON NANOTUBE ON ALUMINUM ALLOY AND ALUMINUM ALLOY HAVING THE COATING

摘要

A method of forming a coating layer comprising carbon nanotubes in an aluminum alloy and an aluminum alloy having a coating layer formed by the method are provided. Method for forming a coating layer comprising a carbon nanotube of the present invention comprises the steps of preparing an aluminum alloy to be coated; Preparing an alkali electrolyte solution including carbon nanotubes by adding carbon nanotubes to the alkali electrolyte solution; And arc oxidation coating the aluminum alloy in the electrolyte. As a result, the micropores are minimized, dense, and colored in black and dark blue to visually beauty, and control the current density, thereby reducing the manufacturing cost and the average cost per unit of production.
