| Summary: | Title screen Self-fluxing nickel-base alloys containing chromium, silicon, boron, and carbon (NiCrSiB) are widely used in industry because of their unique properties. In this study, various amounts of niobium (Nb) powder (2, 4, 6, and 8 wt. %) were added to the self-fluxing powder of an NiCrSiB system in order to obtain more wear-resistant and dense material by using the technology of spark plasma sintering (SPS). SPS of the powder blends was carried out by the SPS 10-4 apparatus (Advanced Technologies, Newport News, VA). The structure and phase composition of the sintered materials were investigated by optical microscopy, scanning electron microscopy, and X-ray diffractometry. This study gives details of porosity and microhardness measurements as well as tribological tests under the friction on the fixed abrasive particles' conditions. This study demonstrates that phases (the central region of which is niobium carbide) are formed at the interfaces and in the junctions between the self-fluxing powder particles. The addition of Nb contributes to the decrease of porosity and the increase of wear resistance. Режим доступа: по договору с организацией-держателем ресурса |
