Research on the Tribology Performance of Copper-Bismuth Bearing Material

Abstract:

Copper-based bearing material containing Bi was prepared by running powder metallurgy process, the influence of the content of Bi on the tribological performance of copper-based bearing materials was inspected and Bi’s impact on frictional wear performance of copper-based bearing materials was studied by a MM-200 frictional wear tester. The research shows that, Bi, with a lower melting point, tends to melt and separate out, in friction process which may reduce shear strength of the friction pair surface and improve the performance of antifriction and adhesiveness resistance. When Bi content gets higher to produce more brittle phases, which will fall off directly from the matrix, the antifriction and antiwear of friction pair will weaken.
