Corrosion behaviour of nanometre sized cerium oxide and titanium oxide incorporated aluminium in NaCl solution

The study highlights the development of an aluminium matrix composite by incorporating mixture of nanometre sized cerium oxide and titanium oxide in pure aluminium and its corrosion resistance in marine environment. The mixed nanometre sized oxides incorporated aluminium exhibited improved microstructure and excellent corrosion resistance. Corrosion resistance depends on the concentration of nanometre sized titanium oxide. Electrochemical characteristics improved several folds in nanometre sized mixed oxides incorporated aluminium than micrometre sized oxides incorporated aluminium.

► Corrosion resistant aluminium incorporated with nano oxides of cerium and titanium.
► 0.2% nano CeO2 and 0.05% nano TiO2 showed increased corrosion resistance.
► Nano TiO2 concentration influenced the optimum performance of the material.
► Comparison of Micro and nano CeO2 and TiO2 aluminium showed the latter is best.
