The applications of plating in a racing powertrain aren’t as widespread as we might find in an automotive engine. Engines in general are reasonably benign environments for metallic components: oil is an excellent anti-corrosion fluid and most o... read more

Doped DLC

Thursday, May 16, 2013
Comments (0)

DLC (diamond-like carbon) coatings are basically diamond, as their name suggests, but most of the coatings marketed as DLC are not these crystalline diamond coatings. Many people labour under the impression that DLC is one coating, but it is in fact ... read more

PVD coatings

Thursday, February 21, 2013
Comments (0)

PVD coatings are used very widely, and cover everything from the metallic coating on the inside of crisp packets to the hard engineering coatings such as titanium nitride (TiN) that we are more familiar with. However, we are most interested in the ha... read more

The main use for ceramic coatings for racing powertrains is on exhaust system components and various heat shields. The very low thermal conductivity of many metal oxides makes them ideal candidates where we would like a coating to reduce heat transfe... read more

Polymer coatings in race engines

Monday, August 13, 2012
Comments (2)

This month's RET-Monitor article on materials discusses some of the uses of polymer materials for manufacturing race engine components. Polymers, in comparison to most engineering metals, generally lack strength and stiffness. They are also often mor... read more

Electroless nickel

Tuesday, July 03, 2012
Comments (2)

The technique of electroless nickel plating has been used widely in race engines for a long time. Electroless nickel is a family of coatings rather than a single coating, and a number of electroless nickel 'composite' coatings are available. Even whe... read more
