Examination of lubrication properties of mineral oils with nanoparticle additives

In this project, titanium dioxide, aluminum oxide and copper oxide particles with spherical shape in nano-size will be used to prepare suspension in mineral oils with different concentrations and so a new nano-oil will be enhanced. Basic reasons of reduce of lifetime and performance of machines and motors which are used in special, commercial or industrial are friction, wear and corrosion. Moreover, the friction is responsible from energy and consumables requirement which rises from the reduction of machine efficiency. Therefore, the friction have importance in machine parts which keep in contact. Nano-oil will bring about an effective increase in performance and lifetime in machine parts. Lubrication performance of lubricant will be determined by ball-on-disc CSM Instruments wear equipment. During wear test, friction coefficient values save as online and stribeck curves will be obtained for each nano-oil. Effects on lubricant of size, type and volume concentration of nanoparticles will be investigated in detail. Tribological tests will performed in specimens which have different surface roughness. And so, the behavior of nano-lubrication on the different surface quality will be determined. Wear rates which occur in base oil and nano-oil will be determined by mechanical profilometer. Main body and counterbody will be analyzed in SEM/EDX and usability of nano-oil will be studied. At the end of the project, it is aimed that a nano-oil which has superior lubrication properties than classical lubrication oils is developed. Thus, in nano-oil systems, an increase in lifetime and efficiency is expected. Reformed nano-oil will assisted to low-energy consumption and environmental protection.
