    Abstract: The invention provides a single or a multilayer PVD coated sharp edged cu tting tool, which can at the same time exhibit satisfactory wear and thermoc hemical resistance as well as resistance to edge chipping. The cutting tool comprises a sintered body made of a cemented carbide, a CBN, a cermet or a c eramic material having a cutting edge with an edge radius Re, a flank and a rake face and a multilayer coating consisting of a PVD coating comprising at least one oxidic PVD layer covering at least parts of the surface of the si ntered body. In one embodiment the edge radius Re is smaller than 40 .mu.m, preferably smaller than or equal to 30 .mu.m. The covered parts of the surfa ce preferably comprise at least some parts of the sharp edge of the sintered body.

    Abstract: This application relates to the reactive cathodic arc evaporation of the composite Al-Cr targets and the nucleation and phase formation of the synthesized Al-Cr-O layers. The oxygen partial pressure and the pulsed operation of the arc current influence the formation of intermetallic phases and solid solutions at the target surface. The nucleation of the ternary oxides at the substrate site appears to be, to some extent, controllable by the intermetallics or solid solutions formed at the target surface. A specific nucleation process at substrate site can therefore be induced by the free choice of target composition in combination with the partial pressure of the oxygen reactive gas. It also allows the control over the oxide island growth at the target surface which occurs occasionally at higher oxygen partial pressure. This is supported by the X-ray diffraction analysis of the layers as well as of the target surface.

    Abstract: The invention provides a single or a multilayer PVD coated sharp edged cutting tool, which can at the same time exhibit satisfactory wear and thermochemical resistance as well as resistance to edge chipping. The cutting tool comprises a sintered body made of a cemented carbide, a CBN, a cermet or a ceramic material having a cutting edge with an edge radius Re, a flank and a rake face and a multilayer coating consisting of a PVD coating comprising at least one oxidic PVD layer covering at least parts of the surface of the sintered body. In one embodiment the edge radius Re is smaller than 40 µm, preferably smaller than or equal to 30 µm. The covered parts of the surface preferably comprise at least some parts of the sharp edge of the sintered body.

    Abstract: Verfahren zum Entschichten von Kohlenstoffschichten, insbesondere von ta-C Schichten von Substratoberflächen von Werkzeugen und Bauteilen. Das zu entschichtende Substrat wird demgemäß auf einen Substrathalter in einer Vakuumkammer angeordnet, die Vakuumkammer wird mit mindestens einem den Abtransport von Kohlenstoff in Gasform unterstützendem Reaktivgas beschickt und eine Niederspannungsplasmaentladung wird in der Vakuumkammer zur Anregung des Reaktivgases und somit zur Unterstützung der erforderlichen chemischen Reaktion bzw. Reaktionen zum Entschichten der beschichteten Substrat erzeugt. Dabei ist die Niederspannungsplasmaentladung eine Gleichstrom-Niedervoltbogenentladung, die zu entschichtenden Substratoberflächen im Wesentlichen werden ausschließlich mit Elektronen beschossen und als Reaktivgas werden Sauerstoff, Stickstoff und Wasserstoff verwendet.
