Our study was focused on identifcation
structure and chemical composition of powder particles released by brake abrasion. The experimental studies were carried
out using Mössbauer spectroscopy, X-ray powder difraction, scanning electron microscopy and magnetic measurements.
Structure and chemical composition of the original brake pads and disc samples were compared with the results obtained for
wear particles. The chemical and phase composition of wear particles is in large part similar to composition of the original
brake pads. Wear particles contained mainly various types of iron oxides, iron and iron carbon metallic particles. The part of
the wear particles showed paramagnetic behaviour at room temperature. The sample with fully paramagnetic wear particles
behaviour was subjected low temperature Mössbauer and magnetic measurements. The results indicate transition interval
corresponding to magnetically ordered states—ferro/antiferromagnetic.Workplace Institute of Physics of Materials Contact Yvonna Šrámková, sramkova@ipm.cz, Tel.: 532 290 485 Year of Publishing 2024 Electronic address https://link.springer.com/article/10.1007/s11696-023-03007-8
