(A1) Bei einem Verfahren und einer Vorrichtung zur Beschichtung der Funktionsflaechen von symmetrisch gezackten Bauteilen, insbesondere der Zahnflanken (3) von Zahnraedern (1), mit einer das Beschichtungsmaterial in Form von elektrisch geladenen Partikeln in Richtung des Bauteils emittierenden, relativ zu diesem umlaufenden Beschichtungsquelle (2) wird erfindungsgemaess auf technologisch einfache Weise eine qualitativ hochwertige Funktionsflaechenbeschichtung des Bauteils dadurch erzielt, dass im Strahlengang zwischen Bauteil (1) und Beschichtungsquelle (2) quer zur Bestrahlungsrichtung eine das Bauteil in einem Umlaufbereich mit flach zur Bestrahlungsrichtung geneigter Funktionsflaechenausrichtung vom Beschichtungsstrahl abschirmende Blende (4) angeordnet ist.

DE 102009004158 A1 UPAB: 20100723 NOVELTY - The process for coating functional surfaces of symmetrically toothed components such as tooth flanks (3) of toothed wheels (1) using a coating source (2) rotating relative to the component and emitting a coating material in the form of electrically charged particles in the direction of the component, comprises shielding the component during the coating process in a peripheral area with a flat functional surface alignment inclined to a beam direction through an aperture (4) from coating beam arranged between the component and coating source transverse to the beam direction. DETAILED DESCRIPTION - The process for coating functional surfaces of symmetrically toothed components such as tooth flanks (3) of toothed wheels (1) using a coating source (2) rotating relative to the component and emitting a coating material in the form of electrically charged particles in the direction of the component, comprises shielding the component during the coating process in a peripheral area with a flat functional surface alignment inclined to a beam direction through an aperture (4) from coating beam arranged between the component and coating source transverse to the beam direction. The component and the coating source are rotated relative to each other around a component axis irregularly with longer dwell times in the rotating position of the functional surfaces steeply engaged to the beam direction. The component is completely coated on half-side over the limit of the peripheral area through the aperture for single-side functional surface coating of the component. The coating is carried out with ion beam or plasma beam. The coating beam is deflected and/or bundled with magnetic and/or electric field. For toothed flanks coating of the bevel wheels, the bevel wheel is rotated around a bevel axis during the coating process and the bevel axis is obliquely engaged in the direction of the coating source. An INDEPENDENT CLAIM is included for a device for coating functional surfaces of symmetrically toothed components such as tooth flanks of toothed wheels. USE - Process for coating functional surfaces of symmetrically toothed components such as tooth flanks of toothed wheels. ADVANTAGE - The process is capable of simply and effectively coating the functional surfaces of the components with high-quality in a less time-consuming manner.
