Titanium Anodizing Chillers

Anodizing of Titanium can be accomplished in many different anodizing solutions from alkaline to acid and almost everything in between. Some of these baths are designed to achieve a specific result and finish. Much of this technology is proprietary and information on it is very difficult or impossible to obtain.

A general type of Titanium anodizing from a sulfuric acid anodizing bath has the following parameters.
I. 155 to 200 g/l sulfuric acid
II. 65-75 degrees Fahrenheit temperature
III. 0-75 volts
IV. 5-15 amps sq ft.
V. 15-20 minutes
VI. Glycol additive (optional)

Pretreatment steps

I. As in all metal finishing a through cleaning must be accomplished, preferably in a strong alkaline cleaner, at 140-160 degrees Fahrenheit for a water break free surface. Electro-cleaning may be desirable but not required. 5-10 minutes.
II. Rinse.
III. Acid etch/activate in 20-50% nitric acid 1-3 minutes. For a more even surface the addition of fluoride is advisable.
IV. Rinse.
V. Anodize at 10 ASF and 10-75 volts depending on final color desired. Color will vary with voltage and time from golden brown at 10 Volts / 20 min to blue at 75 Volts / 12 min.
VI. Rinse.
