摘要
Copper and graphite are the main components of copper-based brake materials commonly used in high-speed trains. Their interaction influences the tribological performance of copper-based brake materials. In this article, with copper and graphite as the materials, three kinds of layered samples were prepared as pins and tested against a disc made of H13 steel. Friction tests were conducted under the condition of 0.8-2.35 m/s and pressure of 0.5 MPa using a pin-on-disc tribometer. Results showed that the friction coefficient decreased with an increase in the angle between boundary orientation and the friction direction in the range of 0 degrees-90 degrees. When the angle was 90 degrees, the interaction between copper and graphite was the strongest. Graphite provided positions for friction film accumulation. Copper and its friction film covered and protected the graphite and boundary and reduced the friction coefficient.
