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
Type Hardness Resistance to Examples of Uses
Alumina oxide Rc 55-65 Wear, heat, high temperature erosion, provides electrical insulation Heat shields, seal surfaces, electrical devices.
Alumina-Titania-Silica Rc 48-52 Abrasion, resistance to molten metals: zinc, aluminum, copper Various; Foundry equipment: pouring ladles, zinc baths; Thick coatings.
Alumina-Titania Rc 55-63 Fretting, cavitation Pump components, textile handling components
Chrome oxide Rc 65-72 Abrasive grains wear Seal surfaces, propeller blades, and mining parts.
Titanium dioxide Rc 65-72 Abrasive grains Pump components, Seal areas.
Zirconium oxide Rc 25-35 High Heat and Oxidation Piston tops, plasma chamber parts.
