Effect of Incremental Copper Powders Third Body on Friction Properties of Q235 Steel

Article Preview

Abstract:

To understand the effects of the third body of copper in the copper-based composite materials on the friction properties, the effect of copper powders on the friction properties of Q235 steel is studied by using the pin-on-disk tester and adding copper powders third body. The results show that when the friction speed at 500-3000 r/min, due to the incremental copper powders, the depth of the furrows on the friction surface was reduced and the adhesion and spalling process of surface third body were intensified, which results that the frictional coefficients of the Q235 steel are increased 0.2-0.35 comparing with that of without adding copper powders. The reason is that incremental copper third body plays the role of increasing the meshing of the asperity and the actual friction area.
