Abstract

One of the many problems that engineers face is the failure of numerous automotive parts due to corrosion. This investigative project was instituted to study the immersion of different types of metal surfaces such as aluminium, mild steel and copper in Moringa non-edible biodiesel at 60?C for 1100 hours. This project gave an insight on the corrosion performance of similar metals immersed in Moringa biodiesels. Besides that, this project had fulfilled its objective to study the elemental composition of selected corrosion spots on the surface of the metal as there were presence of aggressive pitting corrosion on unpolished metal surface than on polished surface. In additions, any colour changes of biodiesels were also recorded as proof of chemical reactions between the metal and biodiesel. The results show that copper had the highest corrosion rate followed by aluminium and lastly, by steel. Marginally changes in biodiesel colour for aluminium and steel when immersed in Moringa biodiesel but the complete opposite was seen when copper was immersed in Moringa biodiesel.
