Abstract:

This report covers Task I of a two-task follow-on program to investigate phosphoric acid non-tank anodize process optimization and evaluation of adhesivesurface preparation combinations. Work completed in Task I included investigating non-tank anodizing process variables of voltage, time, temperature, and rinse delay. Other parameters studied included the effect of anodizing over titanium and aluminum fasteners, battery anodizing, anodizing mode, and identification of common errors occurring in non-tank anodizing. Following the anodizing variables investigation, bond verification tests were conducted to assess bondability of representative RT, 250 F, and 350 F cure adhesive systems. This work will serve as a basis for selecting the phosphoric acid non-tank anodize process parameterconditions for Task II. Author
