This article demonstrated that environmentally friendly lubricants-glycerol-water-based oil (GWB) and rapeseed oil-based oil (RSB)-would provide comparable conditions (wear of node components, friction resistance) in a friction node as a commercial semi-synthetic gear oil (REF). Wear tests were performed on a block-on-ring model friction node stand using GBZ12 (CuSn12), BA1032 (CuAl10Fe3Mn2), and BA1054 (CuAl10Ni5Fe4) bronze samples. Glycerol-water-based oil (GWB) significantly reduced the wear of the samples by several times, compared to semi-synthetic oil (REF) and rapeseed oil-based oil (RSB). The (GWB) oil also provided a stable friction coefficient value at the lowest level of 0.05-0.06. The main disadvantage of the (RSB) oil was the temporary fluctuation of the friction coefficient value (increase above 0.1), which indicated the lack of stability of the boundary layer. The results highlight the potential of (GWB) oil in reducing wear and stabilizing friction under extreme conditions, supporting the shift toward sustainable lubricants in industrial applications.
本文表明,环保型润滑剂——甘油-水基油(GWB)和菜籽油基油(RSB)——在摩擦节点中能提供与商用半合成齿轮油(REF)相当的条件(节点部件磨损、摩擦阻力)。使用GBZ12(CuSn12)、BA1032(CuAl10Fe3Mn2)和BA1054(CuAl10Ni5Fe4)青铜样品在块-环模型摩擦节点试验台上进行了磨损试验。与半合成油(REF)和菜籽油基油(RSB)相比,甘油-水基油(GWB)显著降低了样品的磨损达数倍。GWB油还在最低水平0.05 - 0.06时提供了稳定的摩擦系数值。RSB油的主要缺点是摩擦系数值的暂时波动(增加到0.1以上),这表明边界层缺乏稳定性。结果突出了GWB油在极端条件下减少磨损和稳定摩擦的潜力,支持了工业应用中向可持续润滑剂的转变。
