① Anti corrosion function
② Reduce friction
③ Electrical insulation
Some components typically insulated with ceramic coatings include handheld tools, cable racks, circuits, contact bearings, and engine components.
The application in the aviation industry is a classic direction for the thermal barrier function of ceramic coatings. Due to the tendency of overheated metal components to malfunction, such as thermal fatigue warping and melting, ceramic coatings form an effective thermal barrier to ensure that the metal surface working at high temperatures is damaged, which can prolong the service life of the engine. In addition, the use of thermal barrier ceramic coatings allows for higher internal combustion temperatures (in some cases higher than the melting point of the alloy), resulting in higher thrust efficiency of the turbine. As early as the 1970s, the JD8 engine produced by HP in the United States used 48 coating materials on over 2800 components, effectively extending the engine's overhaul period (from 4000 hours to over 16000 hours). Thermal barrier coating is one of the key technologies for modern aviation engines.
It is obvious that ceramic non stick pots are one of the widely used directions for the non stick performance of ceramic coatings, and in addition, they are also another popular choice for automotive coatings. Ceramic based coatings are more favored than other types of automotive coatings because they can maintain smoothness for a longer period of time, and vehicles do not require frequent waxing.
