铜基铬二铌电触头材料及其制备方法，铜基电触头和空气型高压隔离开关
摘要：
本发明涉及一种铜基铬二铌电触头材料，包括纯铜层以及形成在所述纯铜层上的复合层，所述复合层包括依次层叠设置的多层Cu-Cr2Nb合金层，每层所述Cu-Cr2Nb合金层包括不同质量百分含量的Cu和Cr2Nb，且所述Cu和Cr2Nb的质量百分含量在厚度方向上呈梯度分布，从所述纯铜层往上，每层所述Cu-Cr2Nb合金层中Cr2Nb质量百分含量依次增加。
摘要（英）：

The invention relates to a copper-based chrome-tantalum electrical contact material comprising a pure copper layer and a composite layer formed on the pure copper layer, wherein the composite layer comprises a plurality of Cu-Cr2Nb alloy layers laminated in sequence, each of the Cu-Cr2Nb alloy layers comprises Cu and Cr2Nb of different mass percentages, the mass percentages of the Cu and Cr2Nb arein a gradient distribution in the thickness direction, and the mass percentage of Cr2Nb in each of the Cu-Cr2Nb alloy layers increases sequentially from the pure copper layer upwards.
