Abstract
Disclosed is a piston ring () having a substrate () to which a wear resistant coating () is applied that includes at least one first element with a melting point T≦700° C. The wear resistant coating () contains at least one second element with a melting point T>760° C. The wear resistant coating also includes droplets () which have a diameter (D) and which contain at least the first element, wherein at least 90% of the droplets () have a value 1 μm≦D≦10 μm. In the method for producing a wear resistant coating () using an arc evaporation technique, the target material includes at least one first element with a melting point T≦700° C. and at least one second element with a melting point T>760° C., wherein the quantity of the second material contained in the target material is such that the melting point (T) of the target material ≧1000° C.
