文摘

Carbon nanotube (CNT)- and Fe_p-reinforced copper-matrix composites were successfully fabricated by laser induction hybrid rapid cladding to enhance simultaneously their thermal conductivity and mechanical properties. The microstructure and properties depended on the interaction between CNTs and Fe_p. When the CNT content was 2.6 wt.%, smaller Fe_p and CNTs were uniformly embedded in Cu-rich matrix. The composites exhibited attractive properties including thermal conductivity (197 W m^鈭? K^鈭?), hardness (429HV_0.2), coefficient of friction (0.11) and wear rate (5.3 脳 10^鈭?6 m³ N^鈭? m^鈭? lap^鈭?).
