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

FredGarvin said: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?
FredGarvin said:It 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.
Chemical conversion coating is a surface treatment process that involves the use of chemical reactions to convert the surface of a metal into a corrosion-resistant and paintable layer.
The purpose of chemical conversion coating is to protect metal surfaces from corrosion and to improve their paint adhesion, thus extending the lifespan of the metal.
Chemical conversion coating is commonly used on aluminum, magnesium, and zinc surfaces, but it can also be applied to other metals such as steel and copper.
There are various types of chemical conversion coating, including chromate conversion coating, phosphate conversion coating, and anodizing. Each type has its own unique properties and is used for different applications.
The benefits of chemical conversion coating include increased corrosion resistance, improved paint adhesion, and enhanced surface durability. It also offers cost-effectiveness and environmental friendliness compared to other surface treatment methods.
