Title
(DE) VERFAHREN ZUM BESCHICHTEN VON SOLIDEN DIAMANTWERKSTOFFEN
(EN) METHOD FOR COATING SOLID DIAMOND MATERIALS
(FR) PROCÉDÉ POUR MUNIR DES MATÉRIAUX DE TYPE DIAMANT SOLIDES D'UN REVÊTEMENT
Abstract
(DE) Die vorliegende Erfindung betrifft ein Verfahren zum Beschichten von soliden Diamantwerkstoffen (Solid-PKDs), um die beschichteten Diamantwerkstoffe in eine metallische Oberfläche oder eine zweite Diamantoberfläche unter Raumluft einzulöten oder einzukleben, wobei die Diamantwerkstoffe unter Edelgasatmosphäre mittels eines Dampfabscheideverfahrens wenigstens teilweise beschichtet werden, wobei die Beschichtung mit wenigstens einem carbidbildenden chemischen Element erfolgt, welches ausgewählt wird aus der Gruppe, bestehend aus: B, Ti, Zr, Hf, V, Nb, Ta, Cr, Mo, W; wobei eine Teilmenge des Diamantkohlenstoffs, der in der Oberfläche der Diamantwerkstoffe enthaltenen Diamanten zu Elementcarbiden umgesetzt wird, welche eine Elementcarbidschicht bilden; und wobei das chemische Element im molaren Verhältnis zu den gebildeten Elementcarbiden im stöchiometrischen Überschuss vorliegt, so dass auf die Oberfläche der Elementcarbidschicht eine Elementschicht abgeschieden wird oder sich eine Elementcarbid/Element-Mischschicht ausbildet und auf der entstandenen Elementschicht oder Elementcarbid/Element-Mischschicht abgeschieden wird. Die Erfindung betrifft ferner ein Maschinenbauteil, insbesondere Werkzeug, mit eingelötetem Solid-PKD.
(EN) The present invention relates to a method for coating solid diamond materials (solid PCDs), in order to solder or bond the coated diamond materials into a metallic surface or a second diamond surface under ambient air, wherein the diamond materials are at least partially coated under a noble gas atmosphere by means of a vapour depositing process, wherein the coating is performed with at least one carbide-forming chemical element selected from the group consisting of: B, Ti, Zr, Hf, V, Nb, Ta, Cr, Mo and W; wherein a partial amount of the diamond carbon of the diamonds that are contained in the surface of the diamond materials is converted into elemental carbides, which form an elemental carbide layer; and wherein, with respect to the molar ratio, there is a stoichiometric excess of the chemical element in relation to the elemental carbides formed, and so an element layer is deposited onto the surface of the elemental carbide layer or a mixed elemental carbide/element layer forms and is deposited on the element layer or mixed elemental carbide/element layer occurring. The invention also relates to a machine component, in particular a tool, with a soldered-in solid PCD.
(FR) La présente invention concerne un procédé permettant de munir des matériaux de type diamant solides (diamants polycristallins solides) d'un revêtement, de sorte à souder ou coller les matériaux de type diamant revêtus dans une surface métallique ou une seconde surface de diamant sous atmosphère d'air ambiant, les matériaux de type diamant étant munis d'un revêtement au moins en partie sous atmosphère de gaz rares, au moyen d'un procédé de dépôt en phase vapeur, le revêtement étant effectué avec au moins un élément chimique carburigène qui est sélectionné dans le groupe comprenant : B, Ti, Zr, Hf, V, Nb, Ta, Cr, Mo, W; une quantité partielle du carbonado des diamants contenus dans la surface des matériaux de type diamant étant convertie en carbures élémentaires, lesquels forment une couche de carbures élémentaires. L'élément chimique se trouve en excès stœchiométrique dans le rapport molaire aux carbures élémentaires formés, de sorte qu'une couche élémentaire est déposée sur la surface de la couche de carbures élémentaires ou qu'une couche mixte carbures élémentaires/élément chimique se forme sur ladite surface et qu'une couche de transition est déposée sur la couche élémentaire ou la couche mixte carbures élémentaires/élément chimique obtenue. L'invention concerne également un élément de machine, en particulier un outil, doté d'un diamant polycristallin solide soudé dedans.
