TITANIUM DIOXIDE EFFECTS ON PERFORMANCE CHARACTERISTICS OF DIFFERENT BASED INDUSTRIAL LUBRICANTS

Abstract

TiO₂ has a wide range of usage area. Because of it's tribological properties it is also using in lubrication industry, and it has a good potential to use in different forms in different industries. Bearing control is one of the most important performance characteristics of gear oils. Besides that, additive type and amount, base oil type, ISO VG viscosity class are also important characteristics too.

In this study, we particularly focused on bearing control and base oil types of gear oil formulations. Four different formulation type has been studied: food grade gear oil, synthetic gear oil, traditional gear oil and ester-based gear oil. All formulations are applied respectively 0.2 %-0.5 %-1 % TiO₂ nanoparticles and TiO₂ microparticles.

We have been reported stability, FTIR spectrum, viscosity, viscosity index, weld load performance and wear scar diameters of different lubricant formulations. We have been investigated and also reported particle size effect of titanium dioxide on wear performances of different types of lubricants.
