TY - JOUR A1 - Bettge, Dirk A1 - Starcevic, Jasminka T1 - Quantitative description of wear surfaces of disc brakes using interference microscopy JF - Wear N2 - The technical systems to be investigated are disc brakes and steel–steel rolling contact. The friction processes in a disc brake are rather complex and not yet understood in detail. This is mainly due to the complexity of the brake pad material, which consists of a wide variety of components, and the complexity of the chemical reactions occurring at the wear interface between brake disc and brake pad. Whereas partner projects are studying on the chemistry and the crystallography, we are analyzing the topographic properties of the surfaces involved on the microscopic scale. For this purpose, several methods are known. But besides high lateral resolution, relatively large object fields and height ranges are needed. Interference microscopy was therefore chosen as the main method. This paper deals with its advantages and disadvantages in wear experiments.
