Abstract

The demand for environmentally acceptable lubricants has surged due to awareness of the detrimental effects of petroleum-based lubricants. Vegetable oil-based nanolubricants have garnered significant attention over the past two decades. The present research work focuses on detailed experimental investigation of tribological and rheological characteristics of rice bran oil and sesame oil with trihexyltetradecylphosphonium bis(2,4,4-trimethylpentyl) phosphinate ([P₆₆₆₁₄][BTMPP]) ionic liquid and titanium oxide (TiO₂) nanoparticles as additives. Experiments were conducted using ball on disc tribotester based on central composite design generated by response surface methodology. The study evaluated under three input parameters are load, speed, ionic liquid concentration and two output responses are average coefficient of friction and specific wear rate. Optimal tribological performance has been observed in rice bran oil and sesame oil formulations containing 0.608 vol% and 0.99 vol% of ionic liquid, respectively. Rheological analysis indicated Newtonian behavior across all lubricant samples.

植物油基离子醇润滑剂的摩擦学研究和响应面方法的统计优化

由于人们意识到石油基润滑油的有害影响，对环保型润滑油的需求激增。过去二十年来，植物油基纳米润滑剂受到了广泛关注。本研究工作侧重于米糠油和芝麻油与三己基十四烷基膦双(2,4,4-三甲基戊基)膦酸盐（[P66614][BTMPP]）离子液体和纳米氧化钛（TiO2）作为添加剂的摩擦学和流变学特性的详细实验研究。实验采用基于响应面方法生成的中心复合设计的球盘摩擦试验机进行。研究评估了三个输入参数：载荷、速度和离子液体浓度，以及两个输出响应：平均摩擦系数和特定磨损率。米糠油和芝麻油配方中的离子液体浓度分别为 0.608 Vol% 和 0.99 Vol%，观察到了最佳的摩擦学性能。流变分析表明，所有润滑油样品都具有牛顿特性。
