    <title language="eng">Quantitative description of wear surfaces of disc brakes using interference microscopy</title>
    <abstract language="eng">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&#13;
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.</abstract>

    <title language="eng">Topographic properties of the contact zones of wear surfaces in disc brakes</title>
    <abstract language="eng">Disc brakes are widely used in cars, trains, and other vehicles. For understanding the basic processes occurring during the friction process, information on the surface topography of brake pads and discs is needed, in addition to information about chemistry and thermodynamics. In this paper, samples of pads and discs were analysed using white light interferometry. The topography of the surfaces was measured quantitatively. Using software tools described in a previous paper [Wear 248 (2001) 121], the distributions of area, height, and slope of the contact patches were computed. Characteristic properties of the contact patches were found to describe the influence of the test parameters such as friction power and testing time.</abstract>
