Ceramic Coatings

Precision Coatings, Inc. offers several ceramic coatings applied by Plasma Spray.

Ceramic Coatings

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
  • Erosion
  • Abrasion
  • Galling
  • Hot gases
  • Corrosive liquids
