Precision Coatings, Inc. offers several ceramic coatings applied by Plasma Spray.
Plasma sprayed ceramic coatings have many desirable properties. They are dense, resistant to wear, corrosion, & heat, and inert to most acids, alkalis, and solvents. Ceramic coatings are often used for wear & corrosion resistance and to provide low friction surfaces.
Types of Ceramic Coatings
- Aluminum Oxide
- Alumina-Titania
- Chrome-oxide
- Zirconia based
Ceramic Coatings Resist:
- Fretting
- Sliding wear
