3 Terms and Definitions
The following terms and definitions apply to this document.
3.1
Anodic coating
After anodizing, a dense, uniform and colorful covering layer (film layer) is formed on the surface of the substrate.
Note. The substrate in this document is titanium and titanium alloy, which is called titanium and titanium alloy anodic oxide film.
3.2
Anodizing coating product
Products with an anodic oxide film on the surface.
3.3
alkaline anodizing
Anodic oxidation in alkaline electrolyte.
3.4
acidity anodizing
Anodic oxidation in an acidic electrolyte.
4 Categories
4.1 Anodic oxide films are divided into alkaline anodizing and acidic anodizing according to the preparation method. The film layer codes and typical applications are shown in Table 1.
