  • Publication number: 20050136656
    Abstract: A method for coating a substrate surface where different types of powers are applied to the substrate and different targets. The method involves the formation of a layered structure in the coating where a metal layer is first formed, on top of which is an intermediate layer followed by a top functional layer which is chromium oxide composite. One of the power types is radio frequency power, used particularly for enhancing the efficiency of ionisation and decomposition of the reactive gases in the system. Another type of power, current that is controlled in a pulsed manner, is applied to substrate to improve the alignment of the deposited ions and atoms on the coating surface.
