What metal and what is the purpose of your anodizing, Jake? It makes a huge difference!
For aluminum, the most common anodizing is "Type II" and uses 10 percent by volume sulphuric acid at 68 deg. F and about 15 to 18 ASF. In turn, this requires about 12 to 18 volts. But there is also Chromic Acid Anodizing of Aluminum, and Hardcoat Anodizing, and Spark Discharge Anodizing. Then we move on to magnesium, stainless steel, and titanium anodizing.
For aluminum anodizing, Probert's "Aluminum How To" is a good, easy, introduction, and Wernick, Pinner & Sheasby's "Surface Finishing and Treatment of Aluminum & Its Alloys" is the most complete work on the subject. Good luck.
