Magnesium anodize Bath Control.
Abstract
An analytical method to determine and control the chemical composition and concentration of a magnesium anodizing solution consisting of three chemicals, sodium dichromate, ammonium bifluoride and phosphoric aicd, such as in Chemical Treatment No. 17 of Dow Chemical Company, for example. Automatic pH titration is used to determine the amount of ammonium bifluoride (NH4HF2) and phosphoric acid (H3PO4) concentration at the same time and the concentration of sodium dichromate (Na2Cr2O7 2H2O) is determined separately by the thiosulfate titration technique.
