The Study of Friction Materials in Brake Pad of Small Electric Car
Abstract:
Two kinds of friction materials in small electric car were studied by optical microscope(OM), X-ray diffraction(XRD) and scanning electron microscope(SEM). A sample was composed by Fe-based materials, SiO2, Al2O3 as hard phases, graphite and CaS as lubrications and carbonate and sulfate as fillers. MgO in B sample can increase its hardness, high temperature resistance and friction resistance. The lubrications of B sample consist of graphite and ZnS.
