          Abstract

          In this study, duplex stainless steel was coated with Ni 3Al powder via self-propagating high-temperature synthesis (SHS) and the effect of the sintering temperature on the coating characteristics was investigated. An SEM electron microscope with EDX (energy dispersive X-ray spectroscopy) was used to examine the microstructure of samples that were coated according to the SHS method and likewise to detect the element content of the phases in the structure. Microhardness tests were conducted on the samples to determine the mechanical properties of the coated material. As a result of these studies, it was found that duplex stainless steel can be reliably coated with an Ni 3Al intermetallic compound. The increase in sintering temperature within the given range significantly decreased the size of the disconnected area which completely disappeared.

          Kurzfassung

          In der diesem Beitrag zugrunde liegenden Studie wurde Duplexstahl mit Ni 3Al-Pulver mittels Hochtemperatursynthese (self-propagating high-temperature synthesis (SHS)) beschichtet und die Auswirkungen der Temperatur und Zeitdauer während der Herstellung untersucht. Hierzu wurden Rasterelektronenmikroskopien mittels EDX durchgeführt, um die Mikrostruktur der beschichteten Proben zu untersuchen und die Elementverteilung in den Phasen zu detektieren. Es wurden Messungen der Mikrohärte durchgeführt, um die mechanischen Eigenschaften der Beschichtungen zu prüfen. Als ein Ergebnis stellte sich heraus, dass Duplexstahl zuverlässig mit der intermetallischen Phase Ni 3Al beschichtet werden kann. Mit zunehmender Sintertemperatur wurde die nicht verbundene Fläche auf Null reduziert.
