- Abstract
Bio-lubricants represent a reliable alternative to classical, petroleum-based lubricants. This paper aims to assess the tribological properties of two bio-degradable lubricants, based on sunflower waste cooking oil. Prior to the tribological tests, the rheo-physical properties of the two lubricant samples were determined. The load-carrying properties of both lubricants were evaluated using a four-ball testing machine by employing methods which covered the load-wear variation and the assessment of extreme pressures. The coefficient of friction (COF) and wear scar diameter (WSD), as well as the influence of lubricant temperature, were evaluated. The results obtained for the bio-lubricant candidates were compared with similar studies from literature, and both tested bio-lubricants were proven to have good potential.
