Abstract: The surface of En31 steel was treated by CO2 laser for solid state transformation hardening. The wear and friction characteristics of the treated surfaces were examined and compared with untreated surfaces using the lubricated ring-on-block technique. The microstructures of the laser-hardened tracks and the worn surfaces were studied by SEM. The results indicated that the surface of a single hardened track and the surface with two non-overlapping tracks have better wear and friction properties, as compared with the untreated surfaces. Further, surfaces with non-overlapping tracks were found to have better friction properties than the homogeneous hardened zone of a single track.
