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. Als Flußmittel können Glas, SnO, TiO2 usw. verwendet werden. Als Farbe kommen z. B. Metalloxyde oder keramische Pigmente in Frage. Beschriftungen mit Infrarotlaserenergie sind bsw. in der US-PS 6075223 näher beschrieben. Hochtemperaturbeanspruchte Materialien können z. B. Widerstände, Brennstoffzellen oder Isolierteile sein.The invention relates to a method for permanent labeling of materials exposed to high temperatures, in which an application of flux and color is heated in accordance with the desired labeling by an infrared laser. Glass, SnO, TiO 2 , etc. can be used as the flux. As a color come e.g. B. metal oxides or ceramic pigments in question. Inscriptions with infrared laser energy are, for example. described in more detail in US Pat. No. 6,075,223. Materials exposed to high temperatures can e.g. B. resistors, fuel cells or insulating parts.

Bei diesen hochtemperturbeanspruchten Materialien - z. B. bei 900 Grad Celsius - hat es sich bei Dauerbelastung gezeigt, daß die Beschriftung im Laufe der Zeit weit­ gehend verschwindet. Dies kann ev. auf der Lösung der Farbe im Träger, auf Diffusionsvorgängen oder sonstigen unerwünschten Reaktionen des Substrates beruhen.With these high-temperature materials - z. B. at 900 degrees Celsius - it has it has been shown under permanent load that the lettering expands over time going disappears. This may be due to the solution of the color in the carrier, diffusion processes or other undesirable reactions of the substrate based.

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

Durch die Kristallisation nach der Beschriftung bzw. beim Gebrauch bleibt die Beschriftung dauerhaft erhalten.The lettering remains due to the crystallization after the lettering or during use preserved permanently.

Als gesonderte Zusatzstoffe können z. B. Zirkoniumoxyd, Titanoxyd und Fluor verwendet werden. Sie können ganz oder teilweise entfallen, falls das Flußmittel zur Kristallisation neigt.As separate additives such. B. zirconium oxide, titanium oxide and fluorine used become. They can be omitted in whole or in part if the flux for crystallization inclines.

Anhand eines schematisch dargestellten Ausführungsbeispieles sei die Erfindung näher erläutert, wobei Fig. 1 die Beschriftungsanordnung und Fig. 2 den Auftrag zeigen.The invention will be explained in more detail with reference to a schematically illustrated exemplary embodiment, with FIG. 1 showing the labeling arrangement and FIG. 2 showing the order.

Ein keramischer Träger 1, z. B. ein Hochtemperaturwiderstand aus Al2O3 mit einer Betriebstemperatur von 900 Grad Celsius soll mit einer Beschriftung 2 versehen werden. 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, TiO2). Der Energieabsorber kann entfallen, falls die Farbe absorbiert.A ceramic support 1 , e.g. B. a high temperature resistor made of Al 2 O 3 with an operating temperature of 900 degrees Celsius should be provided with a label 2 . This inscription is created by the corresponding action of the controllable laser beam 4 of an infrared laser on an applied mixture of the actual color a (e.g. metal oxides), flux b and possibly energy absorber c (e.g. SnO, TiO 2 ). The energy absorber can be omitted if the color absorbs.

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

Als Träger der Beschriftung können auch Glas und Metall, z. B. Schmiede­ eisen in Betracht kommen.Glass and metal, eg. B. Forge iron come into consideration.
