Experimental Research Regarding the Obtaining of Friction Elements

Abstract

Friction materials are used as bimetallic friction elements, consisting of a friction material layer sintered on a steel backing. Using the electron microscopy techniques (microprobe analyzer) some of the diffusion processes were investigated, at the interface friction material-steel backing, showing the important role of intermediate layers-electrodeposited copper and sintered Fe-Cu.
