摘要：

Ni-YSZ and Ni-Co-YSZ cermets were fabricated by hot-press-sintering from nanocomposite powders. The structure, morphology, relative density, hardness, specific heat capacity and thermal conductivity were measured. Results show that the crystalline grains are much homogeneous. Their size distribution is quite narrow and between 0.2-0.4 μm (200-400 nm). The Ni-Co-YSZ cermet reaches a maximum relative density (96.2%) at 1350°C and a maximum Rockwell hardness (70.5) at 1400°C. The specific heat capacity of Ni-YSZ cermet is larger than that of Ni-Co-YSZ cermet. The thermal conductivity of Ni-YSZ cermet is smaller than that of Ni-Co-YSZ cermet. © World Scientific Publishing Company.
