Machining after Passivation
December 1, 2008
After passivating parts, can you further deburr the part with sandpaper, etc...? I thought that after passivating it wouldn't be safe to machine or using deburr tools such as using a red wheel, sandpaper, knife, etc....

Any surface work will remove the passivated layer in that area. Also, any clamping by steel clamps may smear iron into the surface. Bad choice!. There is no reason that all of the work can not be completed and inspected if required before the passivation.
