Thanks to the very hard aluminum oxide, the CompCote® surface treatment technique scores with high, alloy- and process-dependent strength. When subjected to abrasion resistance testing (Taber Abraser test), the coating excels with outstanding resistance to wear. Often, it scores better than conventional, anodized coatings. CompCote® coatings are corrosion-resistant. When subjected to notched-bar impact testing, they show a fibrous fracture pattern, whereas conventional oxide layers burst in a brittle way similar to glass.
CompCote® creates an optimized micro structure on the surface: In friction pairings and friction tests, the composite layers show excellent gliding properties – so-called “seizures” as a result of poor lubrication could be excluded. Apart from that, CompCote® coatings can be easily dyed. Our standard colors include black, titan grey, blue, red, gold and green. The colored surfaces are more resistant to light than dyed conventional anodized coatings. CompCote®-H is the variant to go for when it comes to special requirements. This coating is even harder and offers even better wear and corrosion protection.
