Study on Synthesis and Tribological Properties of Chemically modified nanometer TiO2 additive
Abstract: Using TiCl4 as raw materials, nano-titanium dioxide prepared by micro emulsion method, characterized by infrared spectrometer analysis, and four-ball friction and wear experiment machine, after the determination of the nanometer titanium dioxide added to the base oil of friction and wear property and adding amount on the performance of nano-titanium dioxide were studied, the influence of the results showed that nano-titanium dioxide 1.5% (wt %) value is the best; Determination of base oil, adding 1.5% (wt %) of nanometer titanium dioxide base oil, add T202 oil the basis of the three largest no card bit load PB, the results show that after adding T202 PB largest base oil; After the final determination of nanometer titanium dioxide with T202 distribution of friction and chemical properties of both addition amount on friction and wear properties of base oil, the influence of the results showed that when adding 1.5% (wt %) nano-titanium dioxide and adding 1% (wt %) of T202 compound, lubricating oil's anti-wear effect is best.
