Abstract:
(EN) The invention relates to a textile machine tool part (11) which is used in textile processing in a textile machine, and to a method for production of same. The textile machine tool part (11) has a tool core (16) made of a core material which is at least partially coated with an anti-wear layer. The anti-wear layer (17) is applied to a core surface (18) which has a first microstructure (19). The first microstructure (19) is preferably produced by electrochemical etching in the core surface (18). The anti-wear layer (17) applied thereto is preferably applied directly to at least some portions of the core surface (18) comprising the first microstructure (19) by electrochemical deposition and has a layer thickness of at most 20 µm.
(FR) La présente invention concerne une pièce d'outil de machine textile (11) qui est utilisée pour le traitement du textile dans une machine textile, ainsi qu'un procédé pour sa fabrication. La pièce d'outil de machine textile (11) possède un cœur d'outil (16) en matériau de base qui est partiellement recouvert d'une couche de protection contre l'usure. La couche de protection contre l'usure (17) est déposée sur une surface de cœur (18) qui présente une première microstructure (19). La première microstructure (19) est de préférence produite par attaque électrochimique dans la surface de cœur (18). La couche de protection contre l'usure (17) déposée dessus est de préférence appliquée, au moins par endroits, par dépôt électrochimique directement sur la surface de cœur (18) présentant la première microstructure (19) et possède une épaisseur de couche d'au plus 20 µm.
(DE) Die Erfindung betrifft ein Textilmaschinenwerkzeugteil (11), das bei der Textilbearbeitung in einer Textilmaschine verwendet wird, sowie ein Verfahren zu dessen Herstellung. Das Textilmaschinenwerkzeugteil (11) hat einen Werkzeugkern (16) aus einem Kernmaterial, der zumindest teilweise mit einer Verschleißschutzschicht beschichtet wird. Die Ver- schleißschutzschicht (17) wird auf eine Kernoberfläche (18) aufgebracht, die eine erste Mikrostruktur (19) aufweist. Die erste Mikrostruktur (19) wird vorzugsweise durch elekt- rochemisches Ätzen in der Kernoberfläche (18) erzeugt. Die darauf aufgebrachte Verschleißschutzschicht (17) wird vor- zugsweise durch elektrochemisches Abscheiden unmittelbar auf die die erste Mikrostruktur (19) aufweisende Kernober- fläche (18) zumindest abschnittsweise aufgebracht und hat eine Schichtdicke von maximal 20 μm.
