摘要

摘要描述了使用安装在距离接触表面相同距离的两个表面点电位探头测量接触电阻的装置。距离接触表面不同距离的成对探头总数为四个。测量可在真空和空气中进行。首次测试实验表明，改变电流极性不会影响在单片样品或具有一个固定接触面的样品上测量的电流-电压特性。

Installation for Determining the Contact Electrical Resistance of High-Temperature Materials

Abstract—A setup for determining the contact electrical resistance measured using two surface point potential probes installed at the same distance from the contact surface is described. The total number of paired probes located at different distances from the contact surface is four. The reference temperature range is 380–1500 K. Measurements can be performed in vacuum and in air. The setup allows one to investigate the contact resistance at a direct current, which may vary from 20 to 120 A. The first test experiments have shown that changing the current polarity does not affect the current–voltage characteristic measured on a monolithic sample or on a sample with one fixed contact surface.
