Die abhängigen Ansprüche enthalten vorteilhafte Ausgestaltun gen und Weiterbildungen der Erfindung.Solutions according to the invention are in the independent patent claims described. The dependent claims contain advantageous refinements gene and developments of the invention.
Es zeigt sich überraschenderweise, daß durch eine abrasive Behandlung der Oberfläche eines Teils aus Normalstahl und nachfolgende Beschichtung mit einem vorzugsweise durchsichtigen Überzug Birne den optischen Eindruck einer Edelstahloberfläche sehr gut imitierende Erscheinung der Teile aus Normal stahl erreicht werden kann. Das erfindungsgemäße Verfahren ist kostengünstig und mit dem Fachmann an sich geläufigen Mitteln ausführbar.It has surprisingly been found that the abrasive treatment of the Surface of a part made of normal steel and subsequent coating with a preferably transparent coating of pear gives the visual impression of a Stainless steel surface very good imitation appearance of the parts from normal steel can be reached. The method according to the invention is inexpensive and can be carried out with means familiar to the person skilled in the art.
Die abrasive Oberflächenbehandlung kann insbesondere durch Drehen, Bür sten, Schleifen und/oder Polieren erfolgen, wobei für den Schleif- oder Polier vorgang vorteilhafterweise ein Schleifmittel mit einer Körnung von 180 oder fei ner, vorzugsweise mit einer Körnung zwischen 240 und 360 benutzt wird. Bei dieser Oberflächenbehandlung wird vorzugsweise eine Oberfläche erzeugt, welche eine Rauhtiefe mit einer Rauhzahl Rz = 5 bis Rz = 6 aufweist.The abrasive surface treatment can in particular by turning, brushing Most, grinding and / or polishing take place, whereby for grinding or polishing process advantageously an abrasive with a grain size of 180 or fine ner, preferably with a grain size between 240 and 360 is used. At this surface treatment preferably creates a surface which has a roughness depth with a roughness number Rz = 5 to Rz = 6.
Die Beschichtung der abrasiv bearbeiteten Oberfläche erfolgt vorteilhafterweise in geringem Zeitabstand zu der abrasiven Bearbeitung der Oberfläche, um ein Anlaufen oder eine andere die spätere optische Erscheinung beeinträchtigende Veränderung der bearbeiteten Oberfläche zu vermeiden. Die Beschichtung wird insbesondere nicht später als 24 Stunden, günstigerweise nicht später als 6 Stunden, vorzugsweise innerhalb einer Stunde nach der abrasiven Oberflä chenbearbeitung vorgenommen.The abrasive surface is advantageously coated in a short time to the abrasive processing of the surface to a Tarnishing or another which affects the later visual appearance Avoid changing the machined surface. The coating is in particular not later than 24 hours, advantageously not later than 6 Hours, preferably within an hour after the abrasive surface processing.
Die Beschichtung der Oberfläche erfolgt vorteilhafterweise in Form einer Pul verbeschichtung, kann aber auch auf andere an sich bekannte Weisen vorge nommen werden. Bei der bevorzugten Pulverbeschichtung wird vorzugsweise ein Beschichtungsmaterial eingesetzt, welches ein Polyesterlack ist oder zu mindest einen erheblichen, die Materialeigenschaften maßgeblich mitbestim menden Anteil an Polyesterlack enthält. Gebräuchlich sind alternativ oder als Mischungskomponente auch Epoxid-Lacke. Besonders vorteilhaft ist ein Pul ver-Beschichtungsmaterial, welches durch Kornfeinheit Metallglanz Effekt < 125 mg in gebräuchlicher Notation gekennzeichnet ist. The surface is advantageously coated in the form of a pul coating, but can also in other known ways be taken. The preferred powder coating is preferred a coating material is used, which is a polyester paint or too at least a significant one, which significantly determines the material properties contains the proportion of polyester paint. They are used alternatively or as Mixing component also epoxy paints. A pulse is particularly advantageous ver coating material, which due to grain fineness metallic gloss effect < 125 mg is marked in common notation.
Beschichtungsmaterial in Pulverform wird vorteilhafterweise elektrostatisch bei Spannungen zwischen 50 kV und 90 kV aufgebracht, wobei vorzugsweise eine Schicht mit 0,05 bis 0,12 kg/m2, insbesondere ca. 0,08 kg/m2 erzeugt wird. Das in Pulverform aufgebrachte Beschichtungsmaterial wird in an sich be kannter Weise durch Temperatureinwirkung auf der Oberfläche aufgeschmol zen und innig mit dieser verbunden, so daß eine dichte, die Oberfläche insbe sondere vor Korrosion schützende geschlossene Schicht entsteht. Verschiede ne Wärmebehandlungsmethoden für die Pulverbeschichtung (EPS) sind dem Fachmann an sich geläufig. Die Wärmebehandlung erfolgt beispielsweise in einem Temperaturbereich zwischen 150°C und 250°C. Besonders vorteilhaft ist eine Aushärtung über ca. 10 Minuten bei ca. 180°C Objekttemperatur.Coating material in powder form is advantageously applied electrostatically at voltages between 50 kV and 90 kV, a layer with 0.05 to 0.12 kg / m 2 , in particular approximately 0.08 kg / m 2 , preferably being produced. The coating material applied in powder form is melted in a manner known per se by the action of temperature on the surface and intimately connected to it, so that a dense, the surface in particular special protection against corrosion is formed by a closed layer. Various heat treatment methods for powder coating (EPS) are known per se to the person skilled in the art. The heat treatment takes place, for example, in a temperature range between 150 ° C and 250 ° C. Curing over approximately 10 minutes at an object temperature of approximately 180 ° C. is particularly advantageous.
