| Abstract | Cu-W composites that combine the merits of Cu and W show good electric and heat conductivity, resistance to arc erosion, and high strength, etc., and are good candidates for electric contact materials. Until now, several methods, including the high-temperature liquid phase sintering method and the hot-pressure sintering method, have been developed to fabricate Cu-W composites. However, these methods may cause an uneven distribution of constituents in the material and a relatively low density and poor electric conductivity of the material. In this study, a Cu-W composite with micro-oriented W lamellas was prepared by the infiltration method, and the mechanical and electrical properties were investigated and compared with a commercial Cu-W composite. The results showed that the compressive strength of the studied Cu-W composite with micro-oriented W lamellas was between 300 and 1100 MPa when the W content was between 50% and 90% (mass fraction). The compressive strength of the studied composites presented obvious anisotropy, and the strength along the direction parallel to the W lamellas was higher than that perpendicular to the W lamellas. Compared with commercial Cu-W composites with disordered W frameworks, composites with micro-oriented W lamellas exhibit a higher electrical conductivity and compressive strength along the W lamellar direction, which is mainly related to the regular arrangement of the two phases of Cu and W in the composites. The studied composite is expected to be used as an electrical contact material to significantly improve the effect of electric contracts and prolong their service life while reducing the mass of the components and energy consumption.Y |
