Abstract

The physicochemical and tribological studies of mineral and synthetic commercial engine oils have been carried out to investigate their performance variability and to propose generalized relationship among different physicochemical and performance parameters. Physicochemical parameters have been determined using standard test procedures proposed in ASTM and Indian Standards (BIS). The rheological parameters of these lubricants have been investigated to identify the flow behavior. The tribological performance in terms of their antifriction and antiwear properties has been studied using four-ball tribotester. Correlation and regression analysis has been performed to ascertain relationship among physicochemical and tribological parameters and the causes of performance variability are highlighted. An empirical relation to calculate coefficient of friction as a function of physicochemical properties has been established using regression analysis. The developed relation has fair degree of reliability, as percentage of deviation is less than 20%.
机油的理化、流变和摩擦学参数的相关性研究
对矿物油和合成机油进行了物理化学和摩擦学研究,探讨了矿物油和合成机油的性能变异性,并提出了不同物理化学和性能参数之间的广义关系。使用ASTM和印度标准(BIS)中提出的标准测试程序确定物理化学参数。研究了这些润滑油的流变参数,以确定其流动特性。用四球摩擦试验机对其减摩抗磨性能进行了研究。通过相关分析和回归分析,确定了物理化学参数和摩擦学参数之间的关系,并强调了性能变化的原因。通过回归分析,建立了摩擦系数随材料理化性质变化的经验关系式。所建立的关系具有良好的信度,偏差百分比小于20%。
