Hi,
Why is Chemical Conversion Coating done on ducts, fittings in aerospace Industry.

2 ducts are clamped together by a v band coupling.It depends on the part. Processes like anodizing can be for either cosmetic purposes or to increase wear resistance on aluminum parts. Other parts may have a process done to help with electrical conductivity or resistance.
Do you have a specific part or application in mind or is this a homework question?
EXCEPT THE FAYING SURFACE OTHER PARTS OF THE DUCTS ARE ANODIZEDIt sounds like you have a case of relative motion causing wear. The first thing I would make sure is that the V-band clamp is doing it's job and providing the proper clamping force.
I really think you should look into anodizing the parts.
