Publication number: 20070017804Abstract: The present invention relates to a device for improving plasma activity in a magnetron sputtering reactor containing substrates to be coated where a primary plasma is created by a DC or AC voltage applied between the substrates and an additional electrode. Increased plasma activity is obtained by thermionic emission of electrons from a hot filament heated by either DC or AC current or combinations thereof. The device is particularly useful for increasing the adhesion of layers deposited by magnetron sputtering on cutting tool inserts made of cemented carbide, high speed steels, cermets, ceramics or cubic boron nitride.Type: ApplicationFiled: July 21, 2006Publication date: January 25, 2007Inventors: Toril Myrtveit, Markus Rodmar, Torbjorn Selinder

Patent number: 7153562Abstract: The present invention relates to a cutting tool insert particularly for turning of steel comprising a cemented carbide body, a coating with a post treatment with a first, innermost layer system of one or several layers of TiCxNyOz with x+y+z?1 with a total thickness of 0.7–4.5 ?m a second multilayer system consisting of a totally 5–31 alternating Al2O3 and TiCxNyOz (x+y+z?1), preferably ?-Al2O3 and TiN, the Al2O3-layers having an individual layer thickness of <0.5 ?m and the TiCxNyOz-layers 0.01–0.2 ?m with a total thickness of the multilayer of 1.0–4.0 ?m. The multilayer is exposed along the edge line and into the rake and flank face, at least 0.02 mm, from the edge line on the rake face, preferably the contact length of the chip at most 0.9 mm, and 0.02–0.20 mm on the flank face.Type: GrantFiled: January 21, 2004Date of Patent: December 26, 2006Assignee: Sandvik Intellectual Property ABInventors: Markus Rodmar, Mikael Lindholm, Anders Jonsson, Gunilla Andersson, Anders Nordgren, Mikael Lagerquist
