Diamond-Like Carbon (DLC) coatings present the advantage of possessing high hardness (1,500 -3,200 HV) but also a coefficient of friction much lower than that of conventional hard layers such as TiN, TiCN, etc. (5 to 10 times lower).
This unique combination of properties has opened up new possibilities, permitting the improvement of technical parts like engine components, etc. Moreover, these coatings are generally bio- compatible and therefore suitable for food contact and medical applications. So as to meet the various operating conditions encountered by technical components used for automotive and other generic industrial applications, HEF has developed a range of DLC coatings capable of meeting all friction reduction requirements.
