“anel de pistão com um revestimento dlc” um anel de pistão com um revestimento dlc compreende, do interior para fora, sobre um material de base, uma camada adesiva, uma camada de carbono amorfo contendo metal e uma camada de carbono amorfo sem conter metal, onde na camada de carbono contendo metal existem predominantemente ligações sp2 e a camada de carbono sem conter metal compreende ligações sp2 e sp3 , a fração de ligações sp3 sendo maior do que na camada de carbono contendo metal a fim de que ocorra uma resistência elétrica do revestimento dlc que se situa na faixa superior a 5000 ohms, em especial, superior a 5000 kohms. A piston ring with a DLC coating comprises an adhesive layer on a base material from inside to outside, an amorphous metallic hydrocarbon layer and an amorphous non-metallic hydrocarbon layer, wherein primarily sp2 bonds predominate in the metallic hydrocarbon layer and the non-metallic hydrocarbon layer comprises sp2 and sp3 bonds, the sp3 bond fraction being higher than in the metallic hydrocarbon layer so that an electrical resistance of the DLC coating arises, said resistance being in the range greater than 5000 ohms, in particular greater than 5000 kohms.
