Salt spray failures on anodized aluminum: Troubleshooting procedures uncover common problems while systematically isolating areas for further investigation.

Anodize salt spray (SS) failures are infrequent due to the robust BSAA (Boric Acid-Sulfuric Acid Anodizing) process. However, when failures do occur, the problem is rather frustrating due to the numerous possible cases. The Anodize Troubleshooting Guide (ATG) is useful as a checklist to systematically isolate areas for surther investigation. Boeing has used this tecnique on several occasions, and the result has been faster decisions for taking immediate corrective action and successful resolution of the anodize SS failure problem at hand.
