Conductivity and anti-erosion property of TiB_2-W-Cu composites

The TiB2-W-Cu dense composites were prepared through the"cold isostatic pressing—reductive atmosphere sintering—strain hardening" process.The hardness of copper-based composites was enhanced by strain hardening.The hardness,softening temperature,conductivity and anti-erosion performance were examined by using hardness tester,electric arc erosion devices and other equipments.The properties of the prepared copper-based nano-composites are,average conductivity of 4.76×103 S/m,hardness HV=142,softening temperature ≥950 ℃,and electric arc ablation ≤40 μg/C.
