Applications:

• Top coat (insulating layer) in a TBC system for industrial and aviation gas turbine engine components such as combustion liners, transition pieces, afterburners, heat shields, turbine air foils.
• Thermal protection at temperatures up to 1000 °C of metallic substrates used in diesel and gasoline engine components such as cylinder heads, piston crowns, exhaust and intake valves, turbocharger.
• To resist particle erosion at temperatures above 845 °C for rocket nozzles and missile nose cones
• Lining for special purpose crucibles to prevent contamination of the molten contents (Coatings to resist wetting and the corrosive effects of molten metal)
• Coatings on tuyeres for iron forging or refining operation

Calcia Stabilized Zirconia (CSZ) powder is produced through state of the art electric fusion process followed by crushing, grading operations. More specifically Zirconia stabilized with 5% Calcia finds use in the thermal spray industry. Its formulation aims to create thermal barrier coatings offering thermal insulation, resistance to thermal shock, and protection against hot corrosion and sulfidation in high-temperature environments such as combustion chambers. Calcia moderately stabilizes zirconia, mitigating phase transitions as the coating transits to temperature-sensitive zones. Consequently, the coatings exhibit reduced susceptibility to dimensional changes.
