Abstract

New lubricants based on vegetable oil were developed in this study. Different blends of canola oil mixed with fully synthetic two stock engine oils were developed (0, 20%, 40%, 60%, and 80% of synthetic oil).  The viscosity of the prepared blends was determined at different temperatures (20°C–80°C). Tribological experiments were conducted to investigate the effect of the newly developed oil on the wear characteristics of mild steel material compared with stainless steel when subjected to adhesive wear loading. The weight loss (WL) and the specific wear rate (SWR) of the mild steel using each of the prepared lubricants were determined. Scanning electron microscopy was used to examine the worn surface of the mild steel. The results revealed that pure canola oil as a lubricant performed competitively against a blend of 80% synthetic and 20% canola oils. The viscosity of the canola oil and its various blends with synthetic oil are controlled by the environmental temperature since an increased temperature reduces the viscosity. Also, the experimental results revealed that operating parameters play the main role in controlling the wear behavior of mild steel since increasing the sliding distances increases the weight loss. The specific wear rate exhibited a steady state after about 5 km sliding distance, and different blends influenced the applied loads and velocity differently. The mixing ratio of canola and syntactic oil was not particularly significant since the pure canola oil exhibited competitive wear performance compared with the blends. However, an intermediate mixing ratio (40%–60% synthetic oil mixed with 60%–40% canola) can produce a slightly low specific wear rate among other things.
低碳钢在生物润滑条件下的摩擦学行为
本研究开发了以植物油为基础的新型润滑油。菜籽油与完全合成的两种原始发动机油(0%、20%、40%、60%和80%的合成油)混合的不同混合物被开发出来。在不同温度(20°C - 80°C)下测定了所制备的共混物的粘度。通过摩擦学试验,对比研究了新研制的润滑油在黏着磨损载荷作用下对低碳钢材料磨损特性的影响。测定了各配制润滑油对低碳钢的失重率(WL)和比磨损率(SWR)。用扫描电镜对低碳钢的磨损表面进行了观察。结果表明,纯菜籽油作为润滑剂,与80%合成油和20%菜籽油的混合物相比具有竞争力。菜籽油及其与合成油的各种混合物的粘度由环境温度控制,因为温度升高会降低粘度。实验结果还表明,操作参数对低碳钢的磨损行为起主要控制作用,因为增加滑动距离会增加重量损失。在5 km左右的滑动距离后,比磨损率呈现稳定状态,且不同的共混物对加载载荷和速度的影响不同。菜籽油与句法油的混合比例并不是特别显著,因为纯菜籽油与共混物相比具有竞争性的磨损性能。然而,中等混合比例(40%-60%的合成油与60%-40%的菜籽油混合)会产生稍低的比磨损率。
