| abstract |
The invention relates to a coating (2) comprising not only carbon in a predominantly sp2-hybridized form but also at least one first element from the group of transition metals of groups 3 to 10 of the Periodic Table of the Elements, and at least one further element from a group comprising silicon, Germanium, aluminum, and the transition metals of groups 3 to 10 of the Periodic Table of the Elements, with the proviso that the at least one further element is not equal to the first element, wherein the sum of this at least one further element in the coating (2) between 0.1 at% and 5 at% and the sum content of the at least one first element is between 0.5 at% and 10 at%. The coating (2) consists of a layer system of individual layers (6 to 9), which consist of pure elements or at least individual of the individual layers (6 to 9) of a multi-element system of at least two individual elements of the above elements. |
