Chromic acid versus sulfuric acid anodize
WebBoric-Sulfuric Acid Anodize (BSAA) is an alternative to chromic acid anodize. Primary applications include aircraft and aerospace components. It is used for corrosion protection and paint adhesion. Paint adhesion is equal or superior to chromic acid, and the process is more energy-efficient than chrome-based processes.
