Abstract: Corrosive characteristics of biodiesel are important for long-term durability of engine parts. The effect of palm biodiesel on corrosion properties of ASTM 1045 mild steel was studied and compared with that of commercial diesel fuel (0# diesel). Static immersion tests were carried out at different temperatures (27, 50 and 80 °C) for 30, 60 and 120 d. The morphology and composition of corrosion products were characterized by SEM, FT-IR, XRD and XPS. The total acid number was used to investigate the change in acidity of fuel upon exposure. It was found that palm biodiesel is more corrosive than 0# diesel. Temperature and exposure time have critical impact on metal corrosion and degradation of fuels.
