Coatings tested on aluminium pistons
The main advantage of applying Bekaert DLC coatings is that it requires no structural changes to the engine design
Bekaert and Akira Technologies tested the effect on power output and wear resistance of coating aluminium pistons with Bekaert DLC coatings The outcome of these test results will be demonstrated by Bekaert on booth 7066 during Professional Motorsport World

Coating cuts valve train friction levels
Recently performed bench tests show that coating valve train components with the diamond like carbon coating Dylyn Plus can save up to 30% in valve train friction levels.
The trade event takes place in Koln, Germany, from 6th-8th November.
Tests have been performed using a motorcycle engine with standard aluminium pistons.
Results on the dynamometer showed an increase of horsepower of no less than 1% at low rev/min, increasing up to 2% at 13,000rev/min.
The main advantage of applying Bekaert DLC coatings is that it requires no structural changes to the engine design, which is not often the case when searching to increase horsepower.
Marc Herve, Market Manager Racing Europe states: "The Bekaert DLC coating is known to add wear resistance to the piston skirt, but it more importantly reduces the friction between piston and liner".
"This ultimately leads to a higher power output from the engine".
"Aluminium is the major element for pistons, because of its light weight and acceptable strength".
"By coating these pistons with Bekaert DLC coatings, customers are ensured of the durability and strength of their engine components, without having to make structural changes".
"Further tests are currently conducted to determine exactly the increased wear resistance, we foresee the DLC coating will extend the lifetime of the aluminium pistons in race engines".
