摘要
In light of diminishing natural resources, global climatic change and increased environmental sensitivity, renewable-based lubricants are being considered potential alternatives to petroleum-based lubricants. Understanding the tribological performance of vegetable-based lubricants in relation to their chemical composition is essential for their industrial implementation. This study focuses on the friction and abrasion rate characteristics of soybean and sunflower oils in comparison to a base mineral oil under sliding wear at ambient conditions for various applied loads. It was found that the abrasion rate and friction were the least severe for the soybean, followed by the sunflower oil. The observed trends were attributed to differences in their fatty acid compositions, in particular, a lower percentage of linoleic and oleic acids within the soybean oil.
