Aluminum Oxide Coatings

Aluminum Oxide is an engineered ceramic material that is widely used across many applications. It is hard, doesn't react with chemicals and can be used in high temperature operating conditions. It has excellent resistance to abrasive wear, cavitation, particle erosion, friction, heat, and oxidation. High purity materials have excellent dielectric properties and thermal conductivity making it a excellent electrical insulator. Aluminum oxide's wide use and availability at low cost make it viable for many applications.

Aluminum Oxide Coating Benefits
  • Excellent Wear and Abrasion resistance properties up to 3000F
  • High service temperature with Thermal Barrier to 3000F
  • Dielectric strength estimated to be 300-400 volts per 0.001 inch thickness at room temperature
  • Insoluble in aqueous solutions of common acids and alkalis
Applications of Aluminum Oxide Coatings

Aluminum oxide coatings are recommended for chemical and textile industry applications due to its wear properties and chemical inertness. In addition, aluminum oxide's dielectric properties make it useful in industrial components that need to prevent conductivity or electrical shorts. The coating has been used successfully in motor housings, electric railways, and electric components. It's high service temperatures have made it a good candidate for rocket engine thrust chambers and jet engines.
