    Increasing wear resistance of steel is of greatimportance for their practical application. In this paper, wehave studied the tribological performance of assembly ofstearic acid on a carbon steel coated by sol–gel derivedTiO2 film. The samples were characterized by means ofinfrared spectroscopy, contact angle measurements, atomicforce microscopy and a macro friction and wear tester.Enhanced wear resistance were clearly obtained afterfunctionalization of stearic acid on the TiO2 surface.
