We investigated the wear of the nodular graphite cast iron, using Nisihara's wear testing machine, to determine the wear when it is used for the cylinder liner of diesel engine. It was found that, without lubricant, the wear of the nodular graphite cast iron against steel and cast iron was smaller than that of the flaky graphite cast iron, and also good properties to resist wear were obtained in the case of oil lubrication. It became clear that the nodular graphite cast iron with pearlite matrix have more superior properties than that of the other structures.
