Powdery residue on Hard anodized 7075 parts
Powdery residue on Hard anodized 7075 parts
(OP)
I recently had some large 7075 aluminum alloy parts hard anodized at a local Anodizer. The parts are covered with a powdery residue and look extremely dull in appearance. The anodizer has offered no explaination for the appearance of the parts. I quick google search suggests that the parts may have been processed "too hot" resulting in larger than normal pores in the anodize surface. Can anyone offer any addtional explaination for what may have happened? Can the anodized surface be repaired?
Thanks
Thanks
