Tribological Performance of Chemical Modification of NiO-TiO2 Films by Stearic Acid
Abstract: The inorganic-organic composite films with friction reduction and wear resistance were fabricated on 45# steel using sol-gel technology combined with self assembled technology. The thin films of NiO-TiO2 were firstly prepared on steel via a sol-gel method. The stearic acid was then deposited on the NiO-TiO2 films to obtain an organic-inorganic composite film. The contact angle measurements and X-ray diffraction were used to investigate the films’ wetting behavior and crystalline structure, respectively. Their tribological performance was evaluated by a micro tribotester. The results indicate that the composite film shows high hydrophobicity with a water contact angle of 135˚ and good friction-reducing performance.
