Abrasion and erosion behaviour of manganese alloyed permanent moulded austempered ductile iron

Laboratory abrasion and erosion tests have been reported on permanent moulded austempered ductile iron with manganese as alloying element at three levels, i.e., 1%, 2% and 3%. The influences of Mn addition on the wear and tensile properties have been studied and discussed. The results indicate that with increase in Mn content from 1% to 2%, the abrasion and erosion volume losses are exhibiting decreasing trend. Further increase in Mn addition to 3% has resulted in an increase in wear losses. Same is the case with the tensile strength and percentage elongation properties. These data have been interpreted based on the structural features including graphite morphology.
