In this paper results of abrasive and adhesive wear resistance of selected grades of nodular cast iron with carbides are presented. It was demonstrated, that the maximum wear resistance has got nodular cast iron with the microstructure of upper bainite, lower bainite and carbides. This cast iron with hardened steel and sulfonitrided steel is the most advantageous friction pair during adhesive wear testing. It was found, that the least advantageous friction pair is pearlitic nodular cast iron with carbides and normalized steel.

In this paper investigations of abrasive and adhesive wear resistance of different cast iron grades have been presented. Examinations showed, that the most advantageous pair of materials is the cast iron - the hardened steel with low-tempered martensite. It was found, that martensitic nodular cast iron with carbides is the most resistant material.
