    Abstract

    Laser surface melting is carried out using a pulsed NdYAG laser on specimens made of CL60 steel, after that the rolling wear properties of specimens are studied using a MM-P2 rolling friction and wear test machine. The surface topography of the specimens before and after the rolling wear test is measured by a micro XAM 3D surface topography instrument. Metallographic examinations of the specimens are taken out after the rolling wear test using metallographic microscope and scanning electron microscope. It turns out that the laser melted spots stand out during the experiments due to its higher hardness. The laser melted spots are not only reducing the plastic deformation themselves, but also hindering the plastic deformation of vicinity base material on the same circle. The laser melted spots can reduce the scraps peeling off from specimens and the rolling wear resistance is improved. Different distributions of laser melted spots can form different surface topographies after wear.
