Q switched diode-pumped solid-state Nd: YAG laser was adopted to carry out texture processing on the surface of 45 steel. Rolling friction property test of textured samples filled with MoS2 composite solid lubricant containing different mass fractions of PI was examined by a pin-plate line contact friction and wear tester under different working conditions. Wear morphologies and elements distribution were observed and analyzed by SEM. The results indicate that the friction coefficient of textured surface which is filled with bond-type MoS2 solid lubricant decreases as the load and speed increase, and the composite lubricant containing MoS2 plus 20%(mass fraction) PI has the best anti-friction property. The textured surfaces exist oxidation wear, abrasive wear and adhesive wear in the condition of line contact rolling. High speed and heavy load can promote transfer films forming on the counterpart face, and show good anti-friction performance.
