Corrosion effect of ceiba pentandra blends with commercial diesel on aluminium alloys / Vikneswaran Padasivam
Corrosion effect of aluminium alloys in ceiba pentandra biodiesel at various blends with B5 commercial diesel (10%,20%,30%) were investigated. Static immersion test was carried out at ambient temperature for each grade of AA3003, AA5052 and AA6061 for 1200 hours. The compatibility of ceiba pentandra...

| Summary: | Corrosion effect of aluminium alloys in ceiba pentandra biodiesel at various blends with B5 commercial diesel (10%,20%,30%) were investigated. Static immersion test was carried out at ambient temperature for each grade of AA3003, AA5052 and AA6061 for 1200 hours. The compatibility of ceiba pentandra blends with B5 commercial diesel were analysed for its density and viscosity. Microstructure changes of aluminium alloys were observed by both SEM and EDS analysis. The results of corrosion rate showed that the corrosion reaction surges with the increase in concentration of ceiba pentandra biodiesel. The surface morphology reveals the presence of oxide layer as the initial stage of passivation on both B5 commercial diesel and CP10. However, the corrosiveness looks vulnerable for aluminium alloys immersed in both CP20 and CP30 due to the biodiesel concentration whereby both carbon and oxygen element are presence on the EDS analysis.
