Microcharacterization and identification of tire debris in heterogeneous laboratory and environmental specimens

摘要: Abstract Tire debris is produced by the normal wear of tires. Two problems are addressed herewith: characterization particles and their identification in heterogeneous specimens, which come from laboratory tests environment. Both solved analytical electron microscopy (EM). The scanning microscope (SEM) shows that tire has a typical, warped surface pores, its characteristic elements, detected energy dispersive X-ray spectroscopy (EDXS), S Zn. As consequence, specimens straightforward. In those environmental (road dust), where Zn cannot be detected, possible some cases, provided morphology, microanalysis, mapping combined. transmission characterizes on sub-micrometer scale imaging, EDXS, diffraction patterns. microstructure exhibits typical elastomer–filler clusters. representative elementary volume found to approximately 8×10 −23 m 3 .
