This paper discussed the tribofilm properties formed on the contact interface of self-mated austenitic stainless steel lubricated by petrol diesel fuel mixed with 7.5% wt palm methyl ester. To simulate a severe contact condition between the material, a ball-on-disc tribometer was employed. Mild wear condition was found in the case of methyl ester mixed petrol diesel fuel lubrication whereas catastrophic wear was found in the case of petrol diesel fuel lubrication. EDX images revealed significant traces of manganese metallic film on worn scar of the ball in the case of petrol diesel fuel condition. On the contrary, manganese metallic film was found scarcely localised in the case of palm methyl ester mixed petroleum fuel. This indicates that the methyl ester component in the petrol diesel fuel has acted as an agent to prevent the adhesion of manganese metallic film on the contact interface resulting in mild wear of the material.

棕榈甲酯混合石油柴油润滑自配不锈钢摩擦膜的性能

本文讨论了由汽油柴油与 7.5% wt 棕榈甲酯混合润滑的自配奥氏体不锈钢接触界面上形成的摩擦膜特性。为了模拟材料之间的严重接触条件，采用了球盘摩擦计。在甲基酯混合汽油柴油燃料润滑的情况下发现轻度磨损，而在汽油柴油燃料润滑的情况下发现灾难性磨损。EDX 图像显示，在汽油柴油燃料条件下，球的磨损疤痕上有明显的锰金属膜痕迹。相反，在棕榈甲酯混合石油燃料的情况下，几乎没有发现锰金属膜。
