"The study deals with characterization of wear debris generated from commercial brake pad. Brake pads are multicomponent composites which contain more than 10 constituents and polymer matrix. Braking process produces wear particles in form of elements, organic and inorganic compounds. Wear debris may contain several hazardous materials, which may potentially interact with DNA, or cause carcinomas. Wear debris was collected after standard brake dynamometer test and microscopic techniques were used for their characterization. Transmission electron spectroscopy was used to determine size of the emitted nonairborne wear particles. Elemental analysis was performed by scanning electron microscopy with energy dispersive spectroscopy as well as size of the wear particles. Detailed chemical and phase composition of the commercial brake pad is not provided by manufacturers. Furthermore the braking process is accompanied with significant stress and heat generation leading to release wear debris which may significantly differ from initial brake pad. Therefore, Raman microspectroscopy was chosen as additional technique for the characterization of wear particles. In general, Raman spectroscopy provides information about molecular vibrations, which are specific to the chemical bonds and symmetry of molecules, thus these information can be powerful tool for the identification of composition of wear debris emitted by braking. Using the methods described the presence of nano-sized particles and various components based on metal compounds and elemental carbon revealed."@en . "27640" .
