Research on the Effects of TiO2 Nano-admixture in Lubricating Oil
摘要
The effects of TiO2 nano-admixture in lubricating oil were investigated in this paper using a four-ball trimmer, model MRS-10A. The experiments were based on the standard SH-T0762-2005 and involved changing the amount of TiO2 nano-additive in the specialized lubricants (CF-4 15W/40) for diesel engines from 0 to 1%. In order to evaluate the friction surface’s chemical makeup and ability, a wear spot diameter meter, confocal microscope (LCSM), and energy-dispersive spectrometer (EDX) have been used. According to experimental findings, TiO2 nano-admixtures in lubricating oils at various concentrations both reduce friction and wear; however, at a content of 0.5%, friction and wear are minimal. Maintaining the experiment with the load variable from 300 to 700N and the additive content of 0.5% TiO2 nanoparticles all have better effects on reducing friction and wear than pure lubricating oil.
