Abstract

IR laser heating in the application of long-lasting surface markings (2) containing colorants to substrates which are to be subjected to high temperatures involves addition to the marking materials of a substance causing crystallization.

Description

Die Erfindung betrifft ein Verfahren zur dauerhaften Beschriftung von hochtemperaturbeanspruchten Materialien, bei dem durch einen Infrarotlaser ein Auftrag aus Flußmittel und Farbe entsprechend der gewünschten Beschriftung erhitzt wird. The invention relates to a method for the permanent marking of high temperature materials claimed, in which an order from flux and color according to the desired label is heated by an infrared laser. Als Flußmittel können Glas, SnO, TiO 2 usw. verwendet werden. As a flux glass, SnO, TiO 2 etc. can be used. Als Farbe kommen z. As for color come. B. Metalloxyde oder keramische Pigmente in Frage. As metal oxides or ceramic pigments. Beschriftungen mit Infrarotlaserenergie sind bsw. Labels with infrared laser energy are bsw. in der US-PS 6075223 näher beschrieben. described in US Patent No. 6075223 closer. Hochtemperaturbeanspruchte Materialien können z. High-temperature materials such Claimed can. B. Widerstände, Brennstoffzellen oder Isolierteile sein. As resistors, fuel cells or insulating parts to be.

Bei diesen hochtemperturbeanspruchten Materialien - z. These hochtemperturbeanspruchten materials - eg. B. bei 900 Grad Celsius - hat es sich bei Dauerbelastung gezeigt, daß die Beschriftung im Laufe der Zeit weit gehend verschwindet. B. at 900 degrees Celsius - it has been shown in long-term stress that the label will disappear largely over time. Dies kann ev. auf der Lösung der Farbe im Träger, auf Diffusionsvorgängen oder sonstigen unerwünschten Reaktionen des Substrates beruhen. This can ev. Based on the solution of color in the substrate on diffusion processes or other undesirable reactions of the substrate.

Die Aufgabe der vorliegenden Erfindung besteht darin, eine dauerhafte Beschriftung zu erzielen. The object of the present invention is to achieve a permanent label. Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Auftrag Stoffe enthält, die zur Kristallisation der Beschriftung führen. This object is inventively achieved in that the order contains substances which lead to crystallization of the label.

Durch die Kristallisation nach der Beschriftung bzw. beim Gebrauch bleibt die Beschriftung dauerhaft erhalten. By crystallization of the label or in use, the labeling is permanent.

Als gesonderte Zusatzstoffe können z. As separate additives such can. B. Zirkoniumoxyd, Titanoxyd und Fluor verwendet werden. B. zirconium oxide, titanium oxide and fluorine are used. Sie können ganz oder teilweise entfallen, falls das Flußmittel zur Kristallisation neigt. You can completely or partially omitted if the flux tends to crystallize.

Anhand eines schematisch dargestellten Ausführungsbeispieles sei die Erfindung näher erläutert, wobei Fig. 1 die Beschriftungsanordnung und Fig. 2 den Auftrag zeigen. Reference to a schematically illustrated embodiment of the invention will be explained in more detail, FIG. 1, the labeling assembly, and Fig. 2 show the order.

Ein keramischer Träger 1 , z. A ceramic support 1, z. B. ein Hochtemperaturwiderstand aus Al 2 O 3 mit einer Betriebstemperatur von 900 Grad Celsius soll mit einer Beschriftung 2 versehen werden. B. a high temperature resistance of Al 2 O 3 with an operating temperature of 900 degrees Celsius to be provided with a label. 2 Diese Beschriftung entsteht durch die entsprechende Einwirkung des steuerbaren Laserstrahles 4 eines Infrarotlasers auf ein aufgetragenes Gemisch aus eigentlicher Farbe a (z. B. Metalloxyde), Flußmittel b und ggf Energieabsorber c, (z. B. SnO, TiO 2 ). This label is produced by the corresponding action of the controllable laser beam 4 of an infrared laser on a coated mixture of actual color a (z. B. metallic oxides), fluxes b and possibly energy absorber c (z. B. SnO, TiO 2). Der Energieabsorber kann entfallen, falls die Farbe absorbiert. The energy absorber can be omitted if the color absorbed.

Zur Kristallisation der Beschriftung 2 auf dem Träger 1 werden ggf dem Gemisch Zirkoniumoxyd, Titanoxyd und Fluor als Zusatzstoffe beigemengt. For crystallization of the label 2 on the carrier 1 zirconium oxide, titanium oxide and fluorine are added as additives to the mixture if necessary.

Als Träger der Beschriftung können auch Glas und Metall, z. As the support of the label can also glass and metal, eg. B. Schmiede eisen in Betracht kommen. B. wrought iron come into consideration.
