Abstract

Oil additives are some of the most important products since they greatly improve the performance of motor oils and other types of lubricants. This is why the oil additive industry is valued at 14 billion US dollars. One of the types of oil additives is anti-wear additives. Which are used to decrease wear and friction between contacting parts separated by an oil. In this work, the effect of adding talc, graphite and polytetrafluoroethylene (PTFE) with different particle sizes to a blend of glycerin and motor oil on the coefficient of friction and scratch width when a steel ball is in contact with a steel surface is investigated.
 
It was found that adding talc at 2 wt. % showed the lowest value of scratch width at 0.1 mm. Increasing particle size of the graphite additive had a minimal effect on the scratch width but increased the coefficient of friction. The lowest value of the coefficient of friction was found to be at the oil with 3 wt. % graphite at a particle size of 0.012 mm. Increasing the percentage of PTFE additive decreases the scratch width but increases the coefficient of friction.
