Die Verwendung dieses Materials in einem Beschichtungsverfahren ist Gegenstand des Anspruchs 7. Die Ansprüche 8 bis 10 beziehen sich auf die Verwendung eines beschichteten Bauteils in einer Maschine oder einem Apparat, wobei dieses Bauteil ein beschichtetes Substrat gemäss der Erfindung ist.The dependent claims 2 to 6 relate to advantageous embodiments of the coated substrate, the coating of which according to the invention Has composition.

In der einzigen Figur Fig. 1 ist eine Tabelle abgebildet, in der für erfindungsgemäss zusammentgesetzte Legierungen MCrAlXSc die Anteile von Sc und X = Y, Re sowie Ta (in Gew-%) angegeben sind. Die weiteren Legierungsbestandteile wurden konstant gehalten, nämlich 22% für Cr und 8% für Al. Das Matrixelement M, für das Ni gewählt wurde, bildete den Rest der Legierung MCrAlXSc (Ergänzung auf 100%). Es war eine Vielzahl von Proben mit systematisch variierten Zusammensetzungen präpariert worden. Durch Korrosionsversuche mit diesen Proben und unter Anwendung einer besonderen Auswertungsmethode auf die Versuchsergebnisse liess sich eine Rangfolge gewinnen. Die Tabelle bezieht sich auf einen Teil der zwanzig beständigsten Legierungen. Der Rang ist in der letzten Spalte der Tabelle aufgeführt. Die für die Anteile angegebenen Werte sind in der Regel nicht solche der untersuchten Proben; sondern es sind Werte, die sich mittels der Auswertungsmethode, einer statistischen "design of experiments"-Methode, durch Inter- oder Extrapolation ergeben haben. In the single FIG. 1, a table is shown, in which for Alloys MCrAlXSc composed according to the invention of Sc and X = Y, Re and Ta (in% by weight) are given. The others Alloy components were kept constant, namely 22% for Cr and 8% for Al. The matrix element M, for which Ni was chosen, formed the rest of the MCrAlXSc alloy (addition to 100%). It was a variety of Samples with systematically varied compositions have been prepared. By corrosion tests with these samples and using a a special evaluation method based on the test results Win ranking. The table relates to part of the twenty most resistant alloys. The rank is in the last column of the table listed. The values given for the shares are usually not those of the samples examined; Instead, they are values that can be Evaluation method, a statistical "design of experiments" method, have resulted from inter- or extrapolation.
Bei der Auswertung der Versuche wurde die aufgrund von Oxidation entstandene Gewichtszunahme der Proben bestimmt. Bei der Auswertungsmethode wurde dieser Gewichtszunahme die Rolle eines negativen Faktors zugeordnet. Zur Beurteilung der untersuchten Zusammensetzungen wurde ausser der Gewichtszunahme auch berücksichtigt, wieviel Material durch Abplatzen verloren gegangen ist. Die Versuche haben ergeben, dass Scandium Sc einen positiven Einfluss auf die Beständigkeit der Beschichtung hat, dass also Sc eine stabilisierende Wirkung ausübt.The evaluation of the tests was based on oxidation weight increase of the samples determined. In the Evaluation method, this weight gain was the role of a assigned negative factor. To assess the examined In addition to weight gain, compositions was also takes into account how much material has been lost due to chipping. The Trials have shown that Scandium Sc has a positive impact on the Resistance of the coating has that Sc a stabilizing Has an effect.
Es hat sich auch gezeigt, dass durch die Elemente Y, Re und Ta eine teilweise Substituierung bzw. Unterstützung von Sc in Hinsicht auf dessen Stabilisierungswirkung möglich ist. Der Anteil von Sc sollte aber - um eine wesentliche Wirkung zu haben - mindestens 0.5 %, vorteilhafterweise mindestens 1 % betragen.It has also been shown that by the elements Y, Re and Ta one partial substitution or support of Sc with regard to its Stabilizing effect is possible. However, the proportion of Sc should be - by one to have significant effect - at least 0.5%, advantageously amount to at least 1%.
Gute Resultate haben sich ergeben, wenn im Beschichtungsmaterial Re mit einem Anteil zwischen 1 und 2 % sowie Ta mit einem Anteil zwischen 2 und 4 % enthalten sind. Wider Erwarten scheint die Anwesentheit von Cer Ce ungünstig oder zumindest ohne positive Wirkung zu sein. Es sollte daher Ce höchstens in Spuren mit einem Anteil von weniger als 0.1 % in der Beschichtung enthalten sein.Good results have been obtained if Re with in the coating material a share between 1 and 2% and Ta with a share between 2 and 4% are included. Contrary to expectations, the presence of Cer Ce appears to be unfavorable or at least without a positive effect. It should therefore Ce at most in traces with a share of less than 0.1% in the Coating may be included.
Bezüglich der Basislegierung lässt sich folgendes sagen: Das Matrixelement M besteht aus Ni, Co oder einer Kombination von diesen beiden, wobei der Gesamtgehalt von M typischerweise zwischen 60 und 75% liegt.The following can be said regarding the base alloy: The matrix element M consists of Ni, Co or a combination of these two, the Total content of M is typically between 60 and 75%.
Das Beschichtungsmaterial kann mit einem der folgenden Verfahren
aufgebracht werden:
Um einen guten Schutz zu erhalten, muss die Beschichtung relativ dick sein. Die Beschichtung muss dabei so stabilisiert sein, dass bei den vorgesehenen Hochtemperaturbedingungen und einer oxidativen oder korrosiven Belastung während einer vorgegebenen Dauer weitgehend kein Abplatzen von Material erfolgt. Die Dicke der Beschichtung ist vorteilhafterweise grösser als 0.02 mm und kleiner als 0.5 mm.To get good protection, the coating must be relatively thick. The coating must be stabilized so that the intended High temperature conditions and an oxidative or corrosive load largely no flaking off of material for a given duration he follows. The thickness of the coating is advantageously greater than 0.02 mm and less than 0.5 mm.
