Abstract
A hard, wear-resistant aluminum nitride based coating of composition AlSiMeN is proposed; x, y and z denote atomic fractions, the sum of which is between 0.95 and 1.05, and wherein Me is a metal dopant of group III to VIII and Ib transition metals or a combination thereof. The metal provides, during the coating process, an intrinsic electrical conductivity higher than the coating without the metal doping. The silicon content is in between 0.01≦y≦0.4 and the content of the metal dopant or dopants Me is 0.001≦z≦0.8, preferably 0.01≦z≦0.05 and most preferably 0.015≦z≦0.045.
