High-Performance Ceramic Coatings for Extreme Environments
2025-03-18

Ceramic coatings are widely used to refurbish equipment in high-temperature and corrosive environments, such as CVD chambers, PVD chambers, solar cells, and electrostatic chucks. Plasma-sprayed ceramic coatings can be ground to a near-mirror finish, making them ideal for both aesthetic and functional applications. These coatings are also used to strengthen bearings and restore them to near-original condition.
