Vacuum Coaters how the color of titanium and its alloys

Vacuum coating machine titanium and its alloys how the color? Can use DC power supply, voltage regulation range requirements continuously adjustable from 0 ~ 150V, full-wave rectification.
Parts degreasing, pickling can be carried out after the coloring process. There are three types of process recipes to choose from:
(1) 0.1 to 2% phosphoric acid solution.
(2) 0.01% tartaric acid solution.
(3) oxalic acid 5g; citric 5g; lactic 9mL; Phosphate 4 ~ 6mL; water 35mL; ethanol 60mL. During the anodization process, the control of different voltage values, to obtain a different color. Operating voltage reference and color as follows:
8V (yellowish brown); 18V (purple); 22V (dark blue); 26V (blue); 30V (light blue); 42V (yellow); 50V (yellow); 56V (golden); 70V (magenta); 80V (Highland); 90V (green); 100V (dark green).
We are a well-known manufacturer of vacuum coating, a professional vacuum coating equipment, vacuum coating machine manufacturer, is the development, production and sales in one of the national high-tech enterprises.
