Abstract
In wear protection, cobalt-base or nickel-base materials are very often used for coatings in order to increase the functionality and service life of components. These materials such as stellite, the nickel-base alloy Colmonoy 56 or Tribaloy T400 are characterized by a high resistance to abrasion, adhesion as well as excellent corrosion resistance even at higher temperatures.
Given the criticality of cobalt and partly also nickel, it is necessary to look for more sustainable alternatives to be used in wear protection. One possibility is to further develop iron-base materials so that they can be used in wear protection to prevent both abrasion and adhesion. In this context, sufficient corrosion resistance is desirable. This paper will elaborate on the development of a novel intermetallic iron-base hard alloy.
Kurzfassung
Im Verschleißschutz werden sehr häufig Kobalt- oder Nickelbasiswerkstoffe für Beschichtungen verwendet, um die Funktionalität und die Lebensdauer von Bauteilen zu erhöhen. Diese Werkstoffe, wie beispielsweise die Stellite, die Nickelbasislegierung Colmonoy 56 oder die Tribaloy-Legierung T400, zeichnen sich durch eine hohe Beständigkeit gegenüber Abrasion, Adhäsion und eine sehr gute Korrosionsbeständigkeit auch bei höheren Temperaturen aus.
Angesichts der Kritikalität von Kobalt und teilweise auch von Nickel ist es nötig nach nachhaltigeren Alternativwerkstoffen im Verschleißschutz zu suchen. Eine Möglichkeit besteht darin, Werkstoffe auf Eisenbasis so weiterzuentwickeln, dass sie im Verschleißschutz sowohl gegen Abrasion als auch gegen Adhäsion Anwendung finden können. Dabei ist eine ausreichende Korrosionsbeständigkeit wünschenswert. In diesem Beitrag wird auf die Entwicklung einer neuartigen intermetallischen Hartlegierung mit einer Eisenbasis eingegangen.
