Abstract

A metal body for ink transfer and metering in printing units, such as halftone ink applicator rolls, impression cylinders, gravure cylinders, plate cylinders, ink ductors, ink knives, ink blades, mullers and water vibrators (brayers), is provided with a coating of titanium nitride in a layer thickness of between 1 and 8 mu m. For production purposes, the body is preheated to a temperature of up to 500@C, preferably between 380@C and 450@C, whereupon the titanium nitride is vapour-deposited.

Description

Die Erfindung geht aus von einem Metallkörper zur Farbübertragung und -dosierung in Druckwerken der im Oberbegriff des Patentanspruches 1 beschriebenen Art.The invention is based on a metal body for color transfer and -dosing in printing units in the preamble of claim 1 described type.

Es ist bekannt, Metallkörper für den genannten Zweck zur Erhöhung der Standzeiten aus legierten Stählen herzustellen. Sie haben sich insoweit in der Praxis bestens bewährt. Es hat sich doch gezeigt, daß diese Walze auf­ grund ihrer Farbübertragungseigenschaften und der sich hieraus ergebenden Druckqualitäten in bezug auf ihren Einsatz beschränkt sind.It is known to increase the metal body for the purpose mentioned To produce tool life from alloyed steels. So far you have in well proven in practice. It has been shown that this roller on due to their color transfer properties and the resulting Print qualities are limited with regard to their use.

Der vorliegenden Erfindung liegt als Aufgabe die Schaffung von Metall­ körpern der genannten Art mit verbesserten Farbübertragungseigenschaften zugrunde.The object of the present invention is to create metal bodies of the type mentioned with improved ink transfer properties underlying.

Diese Aufgabe wird durch die in Anspruch 1 gekennzeichnete Erfindung gelöst. Durch die erfindungsgemäße Beschichtung wird eine wesentlich ver­ besserte Oberflächengüte, insbesondere geringere Rauhtiefe des Metallkör­ pes erzielt, worauf die erkennbare Verbesserung der Farbübertragungsei­ genschaften zurückgeführt werden kann. Weitere wesentliche Vorteile der erfindungsgemäßen Metallkörper sind hohe Verschleißbeständigkeit gegen Abrasion und Erosion, hohe Korrosionsbeständigkeit, gute chemische Bestän­ digkeit und Temperaturbeständigkeit, geringe Kaltschweißneigung, geringe Reibung, hohe Standheit bei mechanischer Bearbeitung und geringe Kolkver­ schleißbildung.This object is achieved by the invention characterized in claim 1 solved. Due to the coating according to the invention, a substantial ver improved surface quality, in particular lower roughness of the metal body pes achieved, whereupon the noticeable improvement in the color transfer egg properties can be reduced. Other major advantages of Metal bodies according to the invention are highly resistant to wear Abrasion and erosion, high corrosion resistance, good chemical resistance  resistance and temperature resistance, low tendency to sweat, low Friction, high stability with mechanical processing and low scour wear formation.

Die Herstellung der erfindungsgemäßen Metallkörper erfolgt zweckmäßig in der Weise, daß der Körper auf eine Temperatur bis zu 500°C, vorzugsweise zwischen 380°C und 450°C vorgewärmt und danach das Titan­ nitrid aufgedampft wird. Hierbei wird eine gute Haftung der Beschichtung auf dem Metallkörper durch (partielles) Eindiffundieren in den Körper erzielt, wobei sehr enge Toleranzen - was etwa bei der Beschichtung von Rasterwalzen für den Fexodruck bedeutsam ist - eingehalten werden können aufgrund des Umstandes, daß die Beschichtungstemperatur unterhalb der Anlaßtemperatur der zum Einsatz kommenden Stähle liegt.The metal bodies according to the invention are expediently produced in such a way that the body reaches a temperature of up to 500 ° C, preferably preheated between 380 ° C and 450 ° C and then the titanium nitride is evaporated. This ensures good adhesion of the coating on the metal body by (partial) diffusion into the body achieved, with very tight tolerances - such as when coating Anilox rollers is important for fexo printing - can be adhered to due to the fact that the coating temperature is below the Tempering temperature of the steels used.
