Spectroscopic methods in the analysis of wear particles

Abstract Detailed characteristics wear particles formed in various brake pads were done. Our study was focused on identification structure and chemical composition of powder released by abrasion. The experimental studies carried out using Mössbauer spectroscopy, X-ray diffraction, scanning electron microscopy magnetic measurements. Structure the original disc samples compared with results obtained for particles. phase is large part similar to pads. Wear contained mainly types iron oxides, carbon metallic showed paramagnetic behaviour at room temperature. sample fully subjected low temperature indicate transition interval corresponding magnetically ordered states—ferro/antiferromagnetic.
