Abstract
The tribological properties of commonly available fatty acids like Palmatic acid, Oleic acid, Myristic acid, Lauric acid and Steric acid were tested. The fatty acids significantly influence the friction and wear characteristics of vegetable oils. Four ball wear test apparatus was used to carry out tribological tests by varying the normal load. Oleic acid shows the lower coefficient of friction at 100N load because due to the formation of physisorbed layer at low loads. Among the tested fatty acids the descending trend of coefficient of friction shown is as follows: Lauric acid, Myristic acid, Palmitic acid and Stearic acid. Optical microscopy was used to study the wear scar. It was found that the coefficient of friction and wear scar diameter of fatty acids are influenced by chain length, degree of saturation and polarity of fatty acids.
