Abstract

Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung einer Beschichtung auf der Oberfläche eines Substrats durch plasmaelektrolytische Oxidation. Mit dem Verfahren wird ein verbesserter Korrosionsschutz für Leichtmetalle, insbesondere für Magnesium oder Magnesiumlegierungen erzielt. Ferner können auch biokompatible Schutzschichten auf diesen Materialien erzeugt werden mit der Option die Degradation des Substrates zu kontrollieren. Die Schichten zeichnen sich dadurch aus, dass sie amorph sind. Sie werden durch plasmaelektrolytische Oxidation hergestellt, bei dem das Substrat als eine Elektrode zusammen mit einer Gegenelektrode in eine Elektrolytflüssigkeit eingetaucht und eine ausreichende elektrische Spannung zur Erzeugung von Funkenentladungen an der Oberfläche des Substrats angelegt wird, wobei das Elektrolyt darin dispergierte Tonpartikel umfasst. Substrate können daher jegliche aus einem Leichtmetall wie Magnesium oder einer Magnesiumlegierung gefertigte Maschinenbauteile, Automobilbauteile, Eisenbahnbauteile, Flugzeugbauteile, Schiffsbauteile, etc. oder Bioimplantate wie Knochenersatzmaterialien oder medizinische Knochenschrauben sein.The present invention relates to a process for producing a coating on the surface of a substrate by plasma electrolytic oxidation. The process achieves improved corrosion protection for light metals, in particular for magnesium or magnesium alloys. Furthermore, biocompatible protective layers can be produced on these materials with the option to control the degradation of the substrate. The layers are characterized by being amorphous. They are made by plasma electrolytic oxidation in which the substrate is immersed as an electrode together with a counter electrode in an electrolyte liquid and a sufficient voltage is applied to generate spark discharges on the surface of the substrate, wherein the electrolyte comprises clay particles dispersed therein. Substrates may therefore be any engineered components made of a light metal such as magnesium or a magnesium alloy, automotive components, railway components, aircraft components, marine components, etc., or bio-implants such as bone replacement materials or medical bone screws.
