Abstract
A method for coating substrates in an arc vaporization source for generating hard surface coatings on tools is provided. The method includes providing an arc-vaporization source with at least one electric solenoid and a permanent magnet arrangement including marginal permanent magnets and a central permanent magnet. The method further includes adjusting the position of the central and marginal permanent magnets relative to the target surface in at least three settings, adjusting the strength of the generated magnetic field based on the position of the central and marginal permanent magnets among the at least three settings, and coating the substrates by an ARC vaporization coating process performed by the ARC vaporization source at each of the at least three settings.
