Abstract

Vegetable oils as bio-lubricants have poor oxidation stability due to the unsaturated fatty acids in their composition. The oxidation in bio-lubricants can occur because they are exposed to heat, light, and oxygen. In this research, clove oil was used to reduce oxidation in vegetable oils. The effects of blending clove oil (0, 5, and 10% wt) with virgin coconut oil (VCO), hydrogenated coconut oil (HCO), and palm oil that have been exposed to oxygen for 30 days have been investigated. Viscometer and pin-on-disk tests were used to determine the physical and tribological properties of the bio-lubricants. The results show that the addition of clove oil to these oils could reduce the oxidation process. It was indicated by the reduced percentage increase in the dynamic viscosity of 10% wt clove oil in VCO of around 5.41% for 30 days. Results of wear rate indicated that the effect of adding clove oil to VCO and HCO was better than that of palm oil, where the wear rate of VCO and HCO decreased with an increasing clove oil composition. Meanwhile, their coefficients of friction were only affected at low speeds (500 rpm).

含丁香油抗氧化剂的生物润滑剂的摩擦和磨损特性

作为生物润滑油的植物油由于其成分中含有不饱和脂肪酸，因此氧化稳定性较差。生物润滑油之所以会发生氧化，是因为它们暴露在热、光和氧气中。在这项研究中，丁香油被用来减少植物油的氧化。研究了将丁香油（0、5 和 10% 重量百分比）与初榨椰子油 (VCO)、氢化椰子油 (HCO) 和暴露于氧气中 30 天的棕榈油混合的效果。使用粘度计和针盘试验来确定生物润滑剂的物理和摩擦学特性。结果表明，在这些油中添加丁香油可以减少氧化过程。在 30 天的 VCO 中，10% 重量的丁香油的动态粘度增加百分比降低了约 5.41%。磨损率结果表明，在 VCO 和 HCO 中添加丁香油的效果优于棕榈油，VCO 和 HCO 的磨损率随着丁香油成分的增加而降低。同时，它们的摩擦系数仅在低速（500 rpm）时受到影响。
