"Spot" reanodizing
"Spot" reanodizing
(OP)
I have a anodized and painted part which I need to have work done on. It is part of a pressure vessel and the area around the connector o-rings are too rough. There is a fear that they may leak under pressure. I do not wnat to have the entire part stripped, for fear that other critical dimesions may be pushed out of their tolerance range. Are there any ways to re-anodize only the fresh surfaces after the are machined smoother? What haappens when you put an already anodized part with fresh surfaces into a bath?
Any help?

Removing the acid and dam, getting everything clean and sealing afterwards might be a bit of a challenge.

With brush anodizing you will not get the hardest of the anodizing but you will get very good corrosion resistance.
If you just need the corrosion resistance they are chromate conversion coating pens available.
If it is essential to have hard anodizing you can mask off there areas that need protected and just anodize your reworked areas using a strippable coating.
