A method for producing an oxidation barrier layer on a workpiece substrate in which the oxidation barrier layer is produced by means of physical deposition from the gas phase (PVD) and is an oxide that is materially related to the uncoated surface of the workpiece.

Oxidation barrier layer

A coating method based on gas phase deposition by arc evaporation, with the steps: selecting a first target as a material source for the coating; providing a coating chamber with an arc evaporation source including the selected target; loading the chamber with substrates to be coated; pumping down the chamber to a process pressure suitable for the arc evaporation; and igniting and operating the arc such that material is evaporated from the first target and is then deposited on the substrates to be coated, optionally after reaction with a reactive gas admitted into the coating chamber. The first target includes at least one matrix component and one doping component such that the doping component has a melting point at least 500&#xb0; C. lower than the matrix component, and a melted drop of the doping component on a solid surface of the matrix component assumes a contact angle of a least 90&#xb0;.
