Abstract

This paper examines the influence of the graphite morphology on the high temperature abrasive wear behavior of vermicular and nodular cast irons, having same hardness. Wear tests were conducted on a 240-mesh Al2O3 abrasive paper at various temperatures in between 25 and 450 °C. The results showed that in all cases, the nodular cast iron exhibits a higher wear resistance than the vermicular cast iron. Generally the examined vermicular and nodular cast irons exhibit the highest resistance to abrasion at 150°C.
