“…Zhang et al [3] found that the frictional and antiwear behaviour of arachidic acid (C20) were better than that of stearic acid (C18) and behenic acid (C22). Bhuyan et al [4] observed that, with branched fatty acid methyl ester, shorter chains actually have a lower friction than those of longer chains. When Murakami et al [5] compared stearic (C18), oleic (C18-1), linoleic (C18-2), and linolenic acids (C18-3) doped in paraffinic oil in a four-ball wear tester, they found that the polyunsaturated fatty acids have higher scuffing loads and showed better frictional stability at high temperatures.…”

The paper herein proposes a method to simultaneously measure the friction, wear, and thickness of boundary films under a pure sliding contact between metallic surfaces. The method is based on the capacitance method used by Crook and Dyson et al. to measure elastohydrodynamic film thicknesses. Pilot tests conducted on sunflower oil using the new method showed an appreciable growth in the boundary film thickness, with a corresponding drop in the coefficient of friction. Very little wear was observed during the film growth. It is postulated that this growth was due to the polymerization of the unsaturated fatty acid chains.

“…Further, the oleic acid composition play, a vital role in reducing the friction coefficient largely when compared to linoleic and linolenic acids. Higher oleic acid composition is desirable for lower friction [21].…”

The friction and wear tests on AISI 1040 are carried out under raw, modified versions of two nonedible vegetable oils Pongam (Pongamia pinnata) and Jatropha (Jatropha curcas) and also commercially available mineral oil using a pin-on-disc tribometer for various sliding distances and loads. A significant drop in friction and wear for AISI 1040 is observed under Pongam and Jatropha raw oil compared to mineral oil, for the complete tested sliding distance and load, increasing the potential of vegetable oil for tribological applications. Stribeck curves are also drawn to understand the regimes of lubrication. Both the vegetable oils showed a clear reduction in the boundary lubrication regimes, leading to an early start of full film lubrication.

“…Oxygen containing compounds such as fatty acids and their derivatives are superior friction reducing agents [12][13][14][15][16][17][18][19][20][21][22][23][24]. These compounds adsorb or react on rubbing surfaces to reduce adhesion between contacting asperities and limit friction, wear and seizure.…”

Effect of dicarboxylic acid esters on the lubricity of aviation kerosene for use in CI engines

et al. 2013

To reduce their fuel related logistic burden, North Atlantic Treaty Organization (NATO) Armed Forces are advancing the use of a single fuel for both aircraft and ground equipment. To this end, F-34 (the commercial equivalent is Jet A-1) is replacing distillate diesel fuel in many applications. However, tests conducted with this kerosene type on high frequency reciprocating rig showed that this type of fuel causes unacceptable wear. This excessive wear is caused by the poor lubricity of aviation fuel. In order to make this type of fuel compatible with direct injection compression engines, seven di-carboxylic acid esters have tested to improve the lubricity of kerosene. Tribological results showed that all esters tested in this series of experiments seem to be suitable for increasing the kerosene lubricity to a satisfactory level.
