Vielleicht auch Honing? einige Beispiele:

We hone aluminum ram bodies and get them hard anodized so that they meet the dimensional requirements

Anodizing is an electrochemical process used to increase the thickness of the natural oxide layer on the exterior of metal parts. This oxidized surface is easier to work, allowing for more accurate finishing of critical control valve features. Honing and deburring are more effective on anodized components, giving customers a

As noted above, chemically removing the coating (any lye-bearing substance will do it) will produce a bore slightly bigger than before anodizing. I suggest honing, either a copper lap, or an off-the-shelf ball hone for smaller bores, or an automotive style brake hone for larger. Keeping in mind the flexible stuff ...

@ Marc As "Abziehen" has a lot of different significations I kindly ask you to provide more context in regard to technology, purpose, etc. Esp., why is "Abziehen" capable to protect against corrosion? Normally, a protective layer should not be stripped off.
