Characterization of the alumina oxide, copper and nickel powders and their processing intended for fabrication of the novel hybrid composite: A comparative study
Abstract
The aim of this study was the fabrication and characterization of the novel hybridcomposite from the Al2O3/Cu/Ni system. The research included the production ofcomposite specimens by uniaxial pressing and their further sintering. The influenceof the ceramic and metallic powders and their sintering temperature on themicrostructure of composites was investigated. The firing process was conductedin reducing the atmosphere at three different temperatures, selected on the basisof the copper-nickel phase diagram: 1100 °C, 1260 °C, 1400 °C. Reference samplesof Al2O3/Cu were also produced in the same way for comparative purposes.The addition of the third component, which together with copper will form a Niက00 Cusolid solution, was intended to improve the wettability of ceramic matrix through aliquid metallic phase, and thus to reduce the phenomenon of the liquid metal flowon samples surface during sintering. However, it had an impact on physical andmechanical properties.
