Electrical Contact Materials

Copper-based electrical contact materials were prepared by Spark Plasma Sintering (SPS) method and powder metallurgy with the addition of different proportions of rare earth (RE) element. It is found that SPS method greatly enhances the density, hardness and conductivity of the composite materials, thus improving their comprehensive properties. Compared with powder metallurgy, SPS boasts a shorter sintering time, smaller compression force and higher efficiency. RE has considerable influence on the comprehensive properties of copper-based electrical contact materials. When the content of RE lower than 0.1%, the comprehensive properties can be improved by increasing RE.

Conductive Properties

This paper studies the performance change by adding a certain percentage of graphene and high-temperature reduction graphene to copper powder,which would be sinteringed by Spark Plasma Sintering (sps) under certain temperature and pressure. The image of electrical conductivity measured by Physical Property Measurement System (ppms) showed that the electrical conductivity of the sample added with graphene increased by 4.39% compared with the sample added with no graphene. Meanwhile ,hardness increased by 50%. It showed that graphene could improve the conductive properties as well as the strength of copper, which suggests the graphene will have great potential application in power transmission conductor and electrical contact materials.
