Application & selection

Oxide ceramic powders are used in surface engineering where the required coating function may include wear protection, insulation or resistance to a thermal environment. The appropriate function depends on the oxide composition and the coating system.

The supplied ceramic notes highlight the difference in thermal expansion and other properties between a ceramic layer and a metal substrate. Confirm substrate preparation, any bond coat and the spray process along with powder composition and size, then qualify adhesion and coating integrity under the intended conditions.

Details to confirm for this product

• Oxide composition, purity requirements and particle-size distribution.
• Substrate, bond-coat arrangement and spray process.
• Required coating function, adhesion and thermal or wear testing.
