Piston skirt coatings

Friday, May 11, 2012
Comments (2)

If you attend a motorsport trade show and look at the pistons on offer, you will see that a number of them have a coating (or sometimes more than one coating). More often than not, where a single coating is applied to a piston, it will be a skirt coa... read more

Comments (0)

The use of plasma-sprayed coatings has been slow to proliferate; the technique isn't very new, and the range of coatings is immense. Whereas other coating methods can be limited - by solubility of metal salts in electrolytes, for example - plasma coa... read more

Oil-shedding coating applications

Thursday, August 11, 2011
Comments (0)

In a previous article on oil-shedding coatings in summer 2010, I mentioned some of the reasons why they might yield performance gains in an engine where frictional losses due to the action of oil shearing are significant. These coatings are likely to... read more

Comments (1)

The contribution of the piston assembly to overall engine frictional losses is well documented and has been the subject of a lot of research over a number of decades. In SAE paper 911230, for example, the authors Tsuchida and Tsuzuku study the effec... read more

DLC for pistons

Thursday, March 31, 2011
Comments (0)

Pistons are part of the fundamental mechanism of most internal combustion engines, and are certainly very widely employed in racing. While roadcar producers still persist in development of the rotary engine concept, it has been pretty much abandoned ... read more
