Abstract

Globally, there were substantial environmental and economic difficulties linked with the inappropriate treatment and disposal of wasted motor oil. Heavy metals, hazardous chemicals, and other toxins might contaminate soil, water, and air if waste motor oil was not properly treated. The goal of this study was to develop a novel lubricant by incorporating ZDDP and hBN nanoparticles into waste engine oil. The waste engine oil was treated in line with ASTM D-7317 during the procedure. The modified oil was then mixed with 0.2 and 0.5 vol.% ZDDP and hBN nanoparticles, and the samples were homogenized using an ultrasonic homogenizer. A tribological test was performed in accordance with ASTM D-4172 (b), and the CoF and WSD for each sample were calculated. HBN nanoparticle obtain the best result both in WSD and CoF of 0.21 and 1.371(mm) whereas for the worst result it is obvious result obtain for treated used oil with average of WSD and Cof of 0.48 and 1.405(mm). The results obtained from SEM show that the waste engine oil has abrasive and adhesive wear, proving that the oil has the worst results. While hBN nanoparticles show the best SEM results with a cleaner and smoother WSD surface.
