TiAlN-ZrN - SOLID-CARBIDE END MILLING CUTTER HAVING A TIALN-ZRN COATING

摘要

The present invention is a solid carbide milling cutter (SC milling cutter) having a substrate of hard metal and a multilayer coating deposited by a PVD process on at least surface areas that are in contact with the workpiece during milling operation, Comprises a monolayer or multilayer functional layer deposited directly on the surface of the substrate and a monolayer or multilayer cover layer formed on the functional layer, wherein the functional layer has a composition of Ti _x Al _1-x N Wherein the cover layer comprises one or more layers and has a total thickness of 1 to 15 microns, the cover layer comprises one or more layers of ZrN and has a total thickness of 50 nm to 1 占 퐉, the functional layer and the cover layer comprising a high- A power impulse is applied to each sputtering target made of a material to be deposited in a coating chamber during film formation of the functional layer by magnetron sputtering (HIPIMS) The power impulse relates to a solid carbide milling cutter that delivers an amount of energy to the sputtering target in excess of the maximum power density at a pulse of 500 W / cm 2
