“…This phase offers the high wear resistance to this metal. Copper, Molybdenum and Nickel promotes the formation of ausferrite matrix in ADI [3]. Alloying of these elements increase the amount of retained austenite and hence the mechanical properties [4][5][6][7][8].…”

ADI is a material known for Impact toughness, hardness and wear resistance. Carbidic Austempered Ductile Iron [CADI] is a ductile iron which contains high wear resistance alloy carbides in its matrix and is produced by selecting proper composition of material through melting route. Two different alloy compositions of carbon equivalent close to the eutectic composition with variation in the chromium content are used in this study. A detailed microstructure characterization of the material is studied. Effects of austempering parameters on the mechanical properties like impact toughness, hardness and wear resistance are evaluated. Improvements in themechanical properties are found and are correlated with the microstructure. SEM analysis of the wear surface is also studied.

This research is focused on using nitriding to enhance the wear resistance of austempered ductile iron (ADI), ductile iron (DI), and gray iron (GI). Three gas nitriding processes, namely "Gas nitriding + nitrogen cooled down to 800 o F" (Blue), "Gas nitriding + cooled down to 300 o F" (Gray), and "Gas nitriding + oil quenched" (Oil) were used. This study was carried out through optical metallography, roughness measurements, microhardness, and SEM. The ball-ondisc wear tests were conducted under lubricated conditions. It was found that COF for all materials in all nitrided conditions was small (<0.045). The best wear performance was seen for ADI processed using the Gray and Oil gas nitriding processes. These processes produced a compound layer thickness of 4-6μm, a low surface roughness (0.8-1.3 μm, Ra) and a high surface microhardness (1800-2200 HV). The wear rate decreased with increasing surface microhardness and decreasing surface roughness.
