High Temperature Characteristics of a Carbon Strip Sliding against Copper with Electrical Current

CODEN: MPCACD

Abstract

High temperature and arc discharge are two important phenomena that occur in the electrical sliding processes. The extensive adhesive wear, due to high temperature, and arc erosive wear are two mechanisms that potentially cause severe wear of copper-carbon strips with electrical current. Herein, we describe a series of experiments done to better understand the high-temperature characteristics of a carbon strip rubbing against copper with electrical current passing from one to the other. During the experiments, the temperature of the copper-carbon strips was recorded and the wear volumes of carbon strips were measured. The results show that the carbon strip wear volumes are larger when electrical currents pass through the strips. To study how the temperature affects the wear of carbon strips, several wear tests were conducted at an elevated temperature both with and without electrical currents. The results show that adhesive wear is the main mechanism to cause severe wear of carbon strips.
