The present invention relates to a wear resistant coating suitable to be deposited on cutting tool inserts for chip forming metal machining. The coating comprises at least two layers with different grain size, but with essentially the same composition. The coating is deposited by Physical Vapor Deposition (PVD).

PVD coating for metal machining

The invention relates to a coating method for depositing a layer system formed from hard material layers on a substrate, by depositing at least one contact layer including the evaporation material on the surface of the substrate only by means of a cathodic vacuum arc evaporation source. After the depositing of the contact layer, at least one intermediate layer is deposited in the form of a nano-layer intermediate layer in a hybrid phase or as a nanocomposite layer, including the evaporation material and the discharge material, by parallel operation of a cathodic vacuum arc evaporation source and of a magnetron discharge source.

Coating method for depositing a layer system on a substrate and substrate having a layer system

A high-power pulsed magnetron sputtering process, wherein within a process chamber by means of an electrical energy source a sequence of complex discharge pulses is produced by applying an electrical voltage between an anode and a cathode in order to ionize a sputtering gas. The complex discharge pulse is applied for a complex pulse time. The cathode has a target comprising a material to be sputtered for the coating of a substrate, and the complex discharge pulse includes an electrical high-power sputtering pulse having a negative polarity with respect to the anode and being applied for a first pulse-time, the high-power sputtering pulse being followed by an electrical low-power charge cleaning pulse having a positive polarity with respect to the anode and being applied for a second pulse-time. The ratio &#x3c4;/&#x3c4;of the first pulse-time (&#x3c4;) in proportion to the second pulse-time (&#x3c4;) is 0.5 at the most.
