Abstract
Description
Die Erfindung geht aus von einem Verfahren zur Herstellung eines keramischen Schichtverbundes gemäß dem Oberbegriff des Anspruchs 1.The The invention is based on a method for producing a ceramic Layer composite according to the preamble of the claim 1.
Stand der TechnikState of the art
Bei
keramischen Widerstandselementen, wie Glühstiftkerzen mit
einem keramischen Heizelement als Glühstift ist der keramische
Grundkörper des Heizelements mit einer Schutzschicht versehen. Dazu

In
der
Da die mittels thermischen Spritzens aufgebrachten Schutzschichten nicht mit dem keramischen Grundkörper zusammen gesintert werden, entstehen Haftprobleme zwischen dem keramischen Grundkörper und der aufgebrachten Schutzschicht.There the applied by thermal spraying protective layers not sintered together with the ceramic base body become, arise adhesion problems between the ceramic body and the applied protective layer.
Aufgabe der vorliegenden Erfindung ist es, die Verbindung zwischen dem keramischen Grundkörper und der mittels thermischen Spritzens aufgebrachten Schutzschicht zu verbessern.task The present invention is the connection between the ceramic Body and the applied by means of thermal spraying Improve protective layer.
Offenbarung der ErfindungDisclosure of the invention
Die Aufgabe der Erfindung wird mit den kennzeichnenden Merkmalen des Anspruchs 1 gelöst. Durch die Strukturierung der Oberfläche des keramischen Grundkörpers mittels Laserstrahlung ist eine saubere und definierte Aufrauung des keramischen Grundkörpers an der Oberfläche möglich, so dass die anschließend mittels thermischen Spritzens aufgebrachte Schutzschicht besser haftet. Darüber hinaus ist das Verfahren reproduzierbar und mögliche Verunreinigungen, wie sie beispielsweise bei der Präparation durch Sandstrahlen entstehen, werden ausgeschlossen. Eine mögliche Beschädigung des für Hochtemperaturanwendungen eingesetzten keramischen Heizelements ist durch die Aufrauung mittels Laserstrahlung deutlich geringer als das durch Sandstrahlen und dessen eingebrachter mechanischer Energie gegeben ist.The The object of the invention is with the characterizing features of Claim 1 solved. By structuring the surface of the ceramic base body by means of laser radiation is a clean and defined roughening of the ceramic base body possible on the surface, so that afterwards by thermal spraying applied protective layer better liable. In addition, the process is reproducible and possible impurities, such as those at The preparation caused by sandblasting are excluded. A potential damage to high temperature applications used ceramic heating element is by the roughening means Laser radiation is significantly lower than that by sandblasting and whose introduced mechanical energy is given.
Vorteilhafte Weiterbildungen der Erfindung sind durch die Maßnahmen der Unteransprüche möglich. Besonders vorteilhaft ist es, eine gepulste Laserstrahlung einzusetzen, die bei einer Überlappung der Laserspots von 70% bis 90%, vorzugsweise von 80% an der Oberfläche des keramischen Grundkörpers zur Ausbildung von Materialgraten führt, welche bei der nachfolgenden Beschichtung mittels thermischen Spritzens aufgeschmolzen werden, so dass das Material der keramischen Schutzschicht und das Material des keramischen Grundkörpers an der Oberfläche zumindest im Bereich der Materialgrate zu einer chemischen Verbindung verschmelzen. Ein geeignetes Material für die Schutzschicht ist Mullit (Al6Si2O3).Advantageous developments of the invention are possible by the measures of the subclaims. It is particularly advantageous to use pulsed laser radiation which, when the laser spots overlap, leads to the formation of material burrs of 70% to 90%, preferably 80%, at the surface of the ceramic base body, which are melted by thermal spraying in the subsequent coating, so that the material of the ceramic protective layer and the material of the ceramic base body merge on the surface, at least in the region of the material burr, to form a chemical compound. A suitable material for the protective layer is mullite (Al 6 Si 2 O 3 ).
