What are the properties and application characteristics of alumina-zirconia composite powder

       Adding a certain amount of zirconia to the alumina powder can significantly improve the thermal insulation performance and thermal shock resistance of the sprayed coating. When plasma sprayed alumina zirconia coating, the content of zirconia in the coating is in the range of 30%~60%, the sprayed coating is glass-like, the coating is very dense, the bonding strength is high, and the hardness of the coating is at the same time. and reduced electrical insulation properties.



       The alumina zirconia coating is gray, and has excellent heat resistance, high temperature oxidation resistance, gas corrosion resistance, thermal shock resistance and other properties below 900 °C.

       Coatings can be prepared by gas-stabilized plasma, water-stabilized plasma, and supersonic plasma spraying processes.
