Abstract

ADI is an alloy of iron which offers the design engineers the best combination high strength-to-weight ratio, low cost design flexibility, good toughness, wear resistance along with fatigue strength. The aim of the present study is to characterize the corrosion, wear of Austempered Ductile Iron (ADI) developed by the single-step Austempering process.The samples were austempered at different temperatures and the above mentioned properties of these samples were investigated. Experiments were systematically planned to study the Corrosion properties. Wear and corrosion test was conducted on these specimens as per the standard ASTM 897M-90. The samples of Ductile Iron(DI) were first austenised at 925°c for 90 minutes and then austempered by the single-Step Austempering process at temperatures 300°C, 350°C, 400°C, 450°C. The results were found that the corrosion rate is maximum in basic medium and Wear has been observed that ADI Austempered at 350°C has high surface hardness and it is also observed that wear resistance was found to be maximum at 350 0C.
