Abstract This paper focusses on the tribological characteristics of biodegradable Canola Oil Methyl Ester (COME) dispersed with various concentrations of nano-zirconium oxide i.e., ZrO2 - 0.5, 1, and 1.5 wt%. The nano particles are characterized using TEM and XRD analyses. The wear and friction properties were investigated using the four-ball tribometer and the wear and friction monitor. The worn surface and surface roughness analyses were examined using SEM/EDS and atomic force microscopes respectively. The Hastealloy pin material lubricated by COME with 0.5 wt% of ZrO2 shows significant lowering of the values of average frictional torque, mean wear scar diameter, frictional coefficient, wear, and average surface roughness in comparison with other metalworking fluids under study.

纳米氧化锆分散可生物降解菜籽油甲酯金属加工液摩擦学特性评价

摘要 本文重点研究了分散有各种浓度的纳米氧化锆,即 ZrO2 - 0.5、1 和 1.5 wt% 的可生物降解菜籽油甲酯 (COME) 的摩擦学特性。使用 TEM 和 XRD 分析表征纳米颗粒。使用四球摩擦计和磨损和摩擦监测器研究了磨损和摩擦性能。磨损表面和表面粗糙度分析分别使用 SEM/EDS 和原子力显微镜进行检查。与所研究的其他金属加工液相比,由 COME 使用 0.5 wt% ZrO2 润滑的哈氏合金销材料显示出平均摩擦扭矩、平均磨痕直径、摩擦系数、磨损和平均表面粗糙度的值显着降低。
