Composite migrates from the race track
Now available for industrial applications is a nickel (silicon carbide) ceramic composite coating previously almost exclusively used for high-performance racing engines.
Poeton Industries is now offering for industrial applications a nickel (silicon carbide) ceramic composite coating that has until now been used almost exclusively for high-performance racing engines Apticote Ceramic 2000 is used extensively to protect engine surfaces such as cylinder bores and liners, where it provides greater oil retention than steel or chromium

Ceramic coating helps motocross winner
A coating specially developed for motorsport applications has helped Stephen Sword to his second British Motocross Championship.
It is also applied to the aluminium cylinder bores of Wankel engines used in military vehicles and microlight aircraft, where its exceptional wear resistance and low friction properties help the engine to retain compression over very long periods.
Apticote Ceramic 2000 consists of an oleofilic hard metal coating loaded with minute, ultrahard ceramic particles.
It can be finished in a variety of surface topographies, and techniques developed for the racing engine market allow it to be applied to specific tolerances and finished using highly specialised grinding operations if required.
Key properties are an apparent hardness of 580-680Hv, a particle hardness of 2500-3000Hv, a particle loading of 12-14%, a melting point of 1400C and a typical thickness of 60-80um.
Commenting on another significant benefit for industry, Managing Director Colin John says that with coatings such as chromium under constant pressure for environmental reasons, Apticote Ceramic 2000 also offers a more environmentally friendly option.
The coating process itself has been especially tailored for a variety of base materials, including aluminium, steel, cast iron, MMCs, hyperutectic alloys, upon which it outperforms hard chromium as a wear resistant coating.
