摘要

On the microscopic scale cold rolled sheet shows areas of mild plough marks and transverse fissures. Thesecorrespond to boundary lubrication and EHL conditions, respectively, and thus provide some qualitative informationon the governing lubrication regime. This paper features the deviating surface microstructure of some commonlubrication-related surface defects such as mottling and 'white marks', as well as heat scratches and frictionalpickup. In addition, defects attributable to rolled-in dirt and rolled-in scale are discussed, where the local surfacemorphology is often indicative of a deviating local lubrication regime. Possible remedies for these surface defectsare discussed.
