Thermal Barrier Coatings (TBCs) provide an essential protective and insulating layer for engineering products and components that operate in extreme environments eg diesel, gas and turbine engines.
TBCs act to:
Protect against wear and micro-cracking
Prevent oxidation and corrosion
Minimise thermal degradation
Provide thermal insulation
Provide a lubricating surface
Reduce maintenance costs
Improve fuel efficiency by allowing higher burn temperatures
The development and physical application of TBCs is largely driven by technological, economic and societal pressures to increase turbine efficiency by operating them at increasingly higher
temperatures. This improves the efficiency of fuel combustion and therefore reduces cost and contributes to a more environmentally-friendly life cycle of turbine engines.
Our highly dense, nanostructured 4YSZ ceramic powder has very low thermal conductivity at high temperatures, making it the ideal material for TBC ceramic topcoats.
Furthermore, for the easy application of plasma spray coatings, our 4YSZ can be supplied as free-flowing, spherical microgranules or as highly-dispersed, high-solids suspensions – ideal for the
newly emerging suspension plasma spray (SPS) technique.
Visit our 4YSZ product page to discover how our powder is the ideal material for TBC topcoats.
