  • Hard, Wear-Resistant Aluminum Nitride Based Coating
    Publication number: 20080318069
    Abstract: A hard, wear-resistant aluminum nitride based coating of composition AlxSiyMezN 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.
