|Abstract:||The investigation was aimed at exploring the corrosion behaviour of ZA-27 alloy dispersed with graphite particles in controlled environments, both in the as-cast as well as the heat-treated conditions. The corrodents used were fresh HCl solution and SAE 40 engine oil which had been used in an internal combustion engine for 6 months. The composites were found to corrode in the HCl solution, but not in the SAE 40 oil. In each test, the corrosion rate in HCl decreases with time, probably because of the presence of aluminium in the zinc alloy. As the graphite content is increased, the composite becomes more corrosion resistant. Heat treatment at 320°C for a few hours also enhances the corrosion resistance of the composite.
