Tribological Properties of the Lubricant Containing Titanium Dioxide Nanoparticles as an Additive

Abstract

Abstract:To improve the oil-solubility of nanoparticles, a new technology was used to prepare a kind of lubricant containing titanium dioxide (TiO 2 ) nanoparticles. The microstructures of the prepared nanoparticles were characterized via transmission electron microscope (TEM) and infrared spectroscopy (IR). Tribological properties of TiO 2 nanoparticles used as an additive in base oil were evaluated using four-ball tribometer and ball-on-disk tribometer. In addition, the worn surface of the steel ball was investigated via polarized microscopy (PM) and X-ray photoelectron spectroscopy (XPS). The TiO 2 nanoparticles can be completely well-dispersed in the base oil under a new process (NP), which has no significantly negative effect on the anti-oxidation property. The results of the tribological tests show that TiO 2 nanoparticles under the NP show a better anti-wear property and friction-reducing property in base oil compared to TiO 2 nanoparticles under the tradition process (TP). The main aim of this paper lies in solving with the oil-solubility problem through the combination effect of surface modification and special blend process of lubricating oil. This method was first used to prepare lubricant containing TiO 2 nanoparticles and then used as additives in engine oil, gear oil, and other industrial lubricants. At the same time, tribological properties of TiO 2 nanoparticles in base oil as a lubricating additive were also studied.

Experimental Analysis on Nanolubricants Used in Multi Cylinder Petrol Engine With Copper Oxide as Nanoparticle

“…Their study has shown that the CuO nanoparticle has reduced the coefficient of friction compared to lubricants without nanoparticles. [26][27][28][29] They have also concluded that CuO nanoparticle has reduced this depth of wear scar compared with base lubricants. A study on the improvement of the anti-wear with customized palm oil with adding up of CuO and MoS2 was made and the results revealed that, the CuO and MoS2 nanoparticles were effective additives for incorporation into chemically modified palm oil and it has enhanced the anti-wear and extreme pressure properties by 1.5 times.…”

Tribological behaviour of SnO2 nanoparticles as an oil additive on brass

“…In addition, nanofluid experiments conducted with conformal contact are also very limited. Most studies have been conducted using a ball or pin to slide against a disc rotationally . Therefore, the present research examines the tribological behaviour of oil‐based SnO 2 nanofluid using flat‐on‐flat reciprocating sliding tests.…”

“…Most of the previous research studies only focused on the tribological performance of nanofluids on hard metals such as cast iron and steel. 3,5,9,12 Little research was done to investigate antiwear and friction reduction characteristics of nanofluids on soft nonferrous materials such as aluminium and brass. In addition, nanofluid experiments conducted with conformal contact are also very limited.…”

“…Most studies have been conducted using a ball or pin to slide against a disc rotationally. [12][13][14] Therefore, the present research examines the tribological behaviour of oil-based SnO 2 nanofluid using flat-on-flat reciprocating sliding tests. Three-dimensional surface profilometer, optical microscopy, scanning electron microscopy (SEM), and energy-dispersive X-ray spectroscopy (EDX) were used to analyse the worn surfaces and understand the possible wear mechanisms.…”
