Abstract

Nowadays, the demand of new lubricant is highly undoubtedly due to the diverse application that keeps on increasing in industry. It is vital to be studied and produced the new lubricant to meet future demand. The problem is most of the lubricants is derived from the crude oil which is not adaptable to the environment because of its toxicity and non-biodegradability when it is discarded. Due to that problem, the used oil can be threatening to the world if it is not handled correctly. The recycling and regeneration the used oil can be an alternative way to prevent pollution by arranging the composition of the used oil by mixing it with additive oil. The purpose of this study is to determine the optimal design parameters and to indicate which of the design parameters that suitable for obtaining a low coefficient of friction (COF) with hexagonal boron nitride (hBN) nanoparticles, dispersed in fully synthetic engine oil (SN OW20). Design of experiment (DOE) was constructed using the Taguchi method, which consists of L9 orthogonal arrays. Four-ball tester is used for conducting tribological testing by according to ASTM standard D4 l 72 procedures. According to an analysis of SIN ratio, COF and wear scar was reduced significantly with the addition of hBN nanoparticles into the treated engine oil SN OW20. The contribution of 0.1 vol% hBN nanoparticles and 0.3 vol% oleic acid into based oil be can an optimal composition additive to be added in the treated engine oil. Besides, the ideal parameter of the homogenization process is important to be considered as the optimal result obtained when the nano-oil was heated at 4o·c for 30 minutes by ha omogenizer. In addition, the expected reduction in COF and wear was achieved when the hBN functioning well as anti-wear additive.
