Abstract

Nano ZrO₂–TiN (10–40 vol.%) composites were successfully fabricated by spark plasma sintering (SPS) at 1200°C under 80 MPa. The as-obtained composites remained nanosized grains of ZrO₂ and TiN below 200 nm. The physical and mechanical properties of composites were systemically investigated. It was found that above 20 vol.% TiN the composites were electrically conductive. 30 and 40 vol.% TiN reinforced composites possessed the highest flexural strength of 1459.7 MPa and maximum electrical conductivity of 17081.7 S·m⁻¹ respectively.
