Ceracote 484 - A New Aluminum Ceramic Coating with low Cr ⁶⁺ Content for Corrosion Control of Compressor Components

Aluminum-ceramic coatings are well known in aircraft industry as corrosion protective coatings. Especially compressor parts of low alloyed steels or stainless steels-which are in use up to 600°C-are protected by these kind of coatings.

All the available coatings have a lot of chromic acid, causing health problems during application which is done by normal spraying technique.

A new aluminum ceramic coating with low Cr⁶⁺ content has been developed. Properties are presented also in comparison to established systems. The corrosion protection is comparable or better, erosion resistance even superior.
