DLC TREATMENT IN AUTOMOBILES
DLC is an innovative, carbon-based coating that deals with problems related to abrasion, sliding and chemical aggression. Its application to mechanical components of automobile engines is primarily aimed at reducing fuel consumption and thus protecting the environment. The first treatments date back to 2001/2002, initially on heavy vehicles and later on automobiles. This sector, in particular, has prompted more and more research on new, more economic and effective treatment techniques. The main and most exploited characteristic of DLC in this field is its ability to slide: in fact, a reduction in friction and the energy in play results in lower oil consumption and a significant reduction in the emission of pollutants.

DLC TREATMENT IN THE FIELD OF RACING
In the field of competition, DLC technology appeared in F1 in the Nineties thanks to Jean Todt. The Frenchman used it on Peugeot engines and, subsequently, brought this know-how to Maranello when he became Managing Director of Ferrari F1. In 1996-97, everyone in F1 used DLC coatings, on valves and piston parts.
