Tribological analysis of novel apricot oil based biolubricant against 15w40 oil tested on high temperature tribometer

Abstract

Nowadays, petroleum products have become an integral part of day-to-day life. Lubricants made from petroleum products were widely used as automobile lubricants. But the use of petroleum-based lubricants has significantly damaged the environment. The concern of environmental damage caused by petroleum-based lubricants has increased the search for environmentally friendly lubricants. The vegetable oil-based lubricants proved to be environmentally friendly. In the present work, a bio lubricant is produced from the apricot oil, scientifically known as Prunus Armeniaca, using the trans-esterification method. The tribological behavior is analyzed for pure bio-lubricant, 15W40 oil, and also for the blend of apricot oil and 15w40 at different volume percentages. A high-temperature Pin on disc tribometer is used to perform friction and wear tests at 40oC and 100oC. It was found that the blend of apricot oil-based biolubricants and 15W40 lubricant showed better tribological behavior as compared to the pure bio-lubricant and 15W40 oil alone.
