Abstract:
A vacuum process system for surface-treating work pieces uses an arc evaporation source. The system has a first electrode connected to a DC power source and a second electrode, disposed separately from the arc evaporation source. The two electrodes are operated while being connected to a single pulsed power supply.

Abstract:
A set of machining tools containing at least two separate tools is provided, one of which is tailored for a certain type of application and the other tailored for another application or use. The first tool is particularly adapted for applications having service requirements where the coating on the basic body of the tool must have high adhesive strength, but need not have high hardness, and the second tool is for service requirements of high hardness for the hard material coating, where the adhesive strength is not important.
