Wear Resistant Coatings
Typically used to reduce abrasion, fretting, erosion, surface fatigue, and cavitation.
- Carbides
- Ceramics
- Metallics
- Cermets
- Plastics for resisting erosioncally conductive.
Corrosion Resistant Coatings
Typically used to protect surfaces from atmospheric corrosion, chemical attack, alkalis and acids.
- Ceramics
- Metallics
- Plastics
- Cermets
Thermal Barrier Coatings
Typically comprised of Zirconia Oxide and used to protect components from:
- Temperature
- Oxidation
- Wear
Dielectric Coatings
Ceramic Coatings used to electrically insulate substrates.
Electronic Coatings
Metals, typically copper, zinc and aluminum used to make substrate electrically conductive.
