Abstract


This research is mainly concerned with the effect of temperature on anodized aluminum alloys with a view to find better physical and chemical properties of aluminum alloy through the microstructure examination. Four different temperatures were used to vary the electrolyte, the best coating (increase in weight) of 0.994g was obtained from the specimen anodized at 30 0C. As the temperature of the electrolyte increases, the coating thickness decreases. The microstructure test revealed finer grain structure on the specimen at 30 0C and the grain on the microstructure decrease as the temperature of the electrolyte increases. Breaking load of 32KN was realized at a temperature of 30 0C and decreases to 26KN at a temperature of 40 0C.
