A Comparison of Airborne Particles Generated from Disk Brake Contacts: Induction Versus Frictional Heating

Forskningsoutput: TidskriftsbidragArtikel i vetenskaplig tidskrift


Abstract: Volatile emissions of vehicle brakes relate to the high temperature of the brake friction pair. However, as a passive parameter of braking applications, temperature is usually studied together with other parameters such as sliding speed and load. Heating tests that increase the friction pair temperature with an induction heater instead of friction are proposed in this study to imitate the rise in temperature in friction tests. Non-friction airborne particles produced solely by the high temperature in heating tests were studied in comparison with friction tests. The results confirmed the existence of non-friction airborne particles and they can represent about 4.5% of the total airborne particles in friction tests. The high-temperature behaviour as well as the composition of the non-friction airborne particles is also presented. Graphical Abstract: [Figure not available: see fulltext.].
