Abstract

Die vorliegende Erfindung betrifft eine Beschichtung zum Schutz eines Bauteils vor hohen Temperaturen und aggressiven Medien, welche mindestens einen Teilbereich aufweist, deren größter Bestandteil Chrom ist, wobei die Schicht zusätzlich Aluminium umfasst, wobei der Chromanteil zumindest in dem Teilbereich, in dem Chrom der größte Bestandteil ist, größer als 30 Gew.% ist und wobei der Aluminium-Gehalt größer oder gleich 5 Gew.-% ist. Die Erfindung betrifft weiterhin ein Verfahren zur Herstellung einer derartigen Beschichtung zum Schutz eines Bauteils vor hohen Temperaturen und aggressiven Medien, das einen Schritt zur Chromierung der zu beschichtenden Oberfläche und einen
nachfolgenden Schritt der Alitierung der während der Chromierung erzeugten Chrom - reichen Schicht umfasst. Ferner ist Gegenstand der vorliegenden Erfindung ein Bauteil, insbesondere einer Gasturbine, das entsprechend hergestellt wurde bzw. eine entsprechende Beschichtung aufweist.

The present invention relates to a coating for the protection of a component from high temperatures and aggressive media, which has at least a portion whose largest component is chromium, wherein the layer additionally comprises aluminum, wherein the chromium portion at least in the partial area in which chromium is the largest component is greater than 30% by weight and wherein the aluminum content is greater than or equal to 5 % by weight. The invention further relates to a method for producing such a coating for protecting a component from high temperatures and aggressive media, comprising a step for chromating the surface to be coated and a
subsequent step of alitating the chromium - rich layer produced during the chromation. Furthermore, the subject matter of the present invention is a component, in particular a gas turbine, which has been produced accordingly or has a corresponding coating.
