Abstract
Abstract In this study, duplex stainless steel was coated with Ni3Al 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 Ni3Al intermetallic compound. The increase in sintering temperature within the given range significantly decreased the size of the disconnected area which completely disappeared.
