Description

Decorative coloring device and manufacturing method thereof

The present invention relates to a chromogenic device and a method of manufacturing the same, and more particularly to a decorative chromogenic device and a method of manufacturing the same.

Conventional decorative coatings can be distinguished by dry sputtering and wet dyeing processes. Dry sputtering, such as physical sputtering (PVD) decorative coating, is a well-known technique. In the common composition, the decorative coating made of titanium oxide has various color changes, but the plating time is often time-consuming and high. Production costs will be limited for commercial production.

The wet process, such as anodizing, is made by adding a dye to the exterior. In terms of characteristics, the wet process dyeing has a lower price advantage than the sputtering process, but there is no interference color change in the color performance. In contrast, the wet process emphasizes the single color rendering and production.

In the prior art, titanium aluminum nitride (TiAlN) is applied on a tool such as a drill or a piston, and the coating itself exhibits wear resistance and high hardness performance. However, the color of the aluminum nitride titanium coating is relatively monotonous. It has only half-gloss chrome (Red Half-Gloss Chrome) and red wine (Red Tint) colors.
