Combined coating process comprising magnetic field-assisted, high power, pulsed cathode sputtering and an unbalanced magnetron
First Claim
1. A PVD process for coating substrates, wherein the substrate is pre-treated in the vapour of a pulsed, magnetic field-assisted cathode sputtering operation, and during pre-treatment a magnetic field arrangement of a magnetron cathode, with a strength of the horizontal component in front of a target of 100 to 1500 Gauss, is used for magnetic field-assistance, and wherein after pre-treatment further coating is effected by means of cathode sputtering, with a power density of the pulse, magnetic field assisted cathode sputtering operation, during pre-treatment being greater than 1000 W.cm−

Abstract
A PVD process for coating substrates, wherein the substrate is pre-treated in the vapor of a pulsed, magnetic field-assisted cathode sputtering operation, and during pre-treatment a magnetic field arrangement of the magnetron cathode type, with a strength of the horizontal component in front of the target of 100 to 1500 Gauss, is used for magnetic field-assistance, and after pre-treatment further coating is effected by means of cathode sputtering and the power density of the pulsed discharge during pre-treatment is greater than 1000 W.cm−2.
