At the 1990 Annual Aerospace/Airline Plating and Metal Finishing Forum, The Boeing Commercial Airplane Group presented information on boric acid/sulfuric acid anodizing (BSAA) as a replacement for chromic acid anodizing (CAA) to meet environmental regulations.This paper presents an update on the BSAA process and the status of production implementation. Background information will be reviewed including environmental issues and modifications of CAA to meet current EPA regulations.The results of BSAA process optimization, corrosion protection performance and compatibility with aircraft finishing will be given. Production implementation experience such as process control and facility requirements, including the status of BSAA for MIL-A-8625, Type IC (Anodizing, Non-chromic Acid, Meeting Type I Requirements) usage will be reviewed.
