Özet

In this study, densification of TiB2 with the addition of 316L grade stainless steel powder by using the vacuum arc melting (VAM) process was investigated. 316L and TiB2 powders were mixed in predetermined amounts and pressed to form pellet shaped samples which were later heated in the VAM. Microstructures of the samples were examined by SEM and an optical microscope. It was observed that TiB2 grains in the samples were wetted by the molten stainless steel phase. Furthermore, it was noted that the sample composition and arc current in the VAM affected the densification behavior of the samples. This kind of a material processing technique can be used to build up a composite layer over different substrates as well as over selected surfaces of machine parts.
