Abstract

The paper demonstrates that as the energy industry develops, there is a continuous process of improving the designs of contact electrical connections. Bimetallic contacts are becoming more common. Their performance depends on the morphology and strength of the connection layers. Clad workpieces with various heat treatment modes were researched. The strength of the joint of the laminated compound was also determined. With increasing temperature and heat treatment time, the concentration as well as the amount of intermetallic compounds in the weld zone increases. When the layer of intermetallic compounds reaches a certain value, the effects of increasing temperature and increasing time are weakened. Observations show that a low annealing temperature with a short heat treatment time can significantly improve the strength of the clad compound joint.
电双金属触点的形貌和力学特性研究
本文表明,随着能源工业的发展,接触电气连接的设计也在不断改进。双金属触点正变得越来越普遍。它们的性能取决于连接层的形态和强度。对不同热处理方式的覆层工件进行了研究。测定了复合材料的接头强度。随着温度的升高和热处理时间的延长,焊缝区金属间化合物的浓度和数量均有所增加。当金属间化合物层达到一定值时,温度升高和时间延长的影响减弱。观察结果表明,较低的退火温度和较短的热处理时间可以显著提高包覆复合接头的强度。
