Re: Anodizing flaking off.
Wow, wierd... never seen that happen before.
Looks like a CP on/off? I know those are 6000 or 5000 series, so shouldn't be a problem with mixed batch over-anodizing. Maybe something different with the prep? When you peel off the layer, is it chalky at the base metal? What prep, ano temp, CD, duration, and sealing method?

Re: Anodizing flaking off.
The Part was redone and came out fine. The layer wasnt chalky, My acidbath was ~69-72, only one side flaked, and only after it was sealed. Sealed in boiling nickel acetate. I could peel it off in little sheets, when I peeled the flakes off, the metal underneath was fine, still glossy and smooth. I dont remember the CD since I use CV anodizing instead of CC.
I did about 25 parts in that load, and only this part did it. Last edited by destroyer125; 12-26-2006 at 01:24 PM.

Re: Anodizing flaking off.
Don't boil your sealer, 190 degrees is all it needs. Boiling can shorten it's life.
