As we all know, ceramic coatings are widely used in car industry and provide a hard barrier between your car’s exterior paint and the environmental contaminants. The coatings consist of a molecular compound paired with Silicon Dioxide or better know as liquid glass. It provides a clear glass-like coating on your vehicle to protect it from the harsh UV rays , acid rain, bird droppings, bugs from the late night summer drive, as well as tar from the road. There are different ceramic spray agents for ceramic coating:
Aluminium oxide+Titanium dioxide
Up to ca. 500°C this ceramic coating also provides protection against most acids and alkaline. Its dielectric properties are not has high as in pure aluminium oxide due to the titanium oxide component. Due to the greater hardness compared to white ceramic this dark blue ceramic coating is for example favoured for pumps, valve discs, valve shafts, wire drawing drums and thread guides.
This ceramic coating is non conductive and is therefore used for electric insulation. This pure ceramic coating provides good resistance against abrasion, wear of gliding, friction and oxidation.
The chrome oxide ceramic coating can also be applied up to ca. 500°C and is resistant against acids, alkaline and alcohol. The hardness is approx. Chrome oxide is therefore commonly used as sealing for pump sealants, sealing rings, shaft protection sleeves, guide rollers etc. The chrome-oxide-ceramic coating obtains higher wear and corrosion protection.
This special ceramic coating is used by companies in vacuum plasma ceramic spraying processes for medical technology for the coating of hip, shoulder and knee joints.
The Yttruim stabilised ceramic coating is widely used as thermal insulation barrier. It is scratch resistant, high temperature resistant, thermo shock resistant and can also be used in high gas corrosive and sulphur and sodium rich environments. Typical applications of this ceramic coating are the jet engines, cylinder heads, aviation industry, rockets and coating for metal welding and tanks.
