Comparison Of Bio-Oil And Synthetic Lubricants Tribological Characters

Bio-lubricants have been developed as an alternative to mineral oil-based lubricants because of environmental concerns and the diminishing supply of petroleum. Vegetable oils (red palm oil, soybean oil, coconut oil and sunflower oil) were studied as bio-lubricants and their mixes with anti-wear addi...
