EVALUATION OF SINTERED CARBIDES WEAR RESISTANCE

Abstract. The paper contains the laboratory test results of selected metal materials abrasive wear resistance using the apparatus with abrasive cloth. The wear rate comparison of cast iron, selected steel types, selected overlay types and sintered carbides have been the aim of carried out tests. The results show that the wear values of overlays and especially of sintered carbides are expressively lower than these ones of cast iron or constructional steels. Therefore they can be considered for perspective materials for the use for agricultural machines active parts. Key words: wear, wear intensity, laboratory tests, pin-on-disk machine, sintered carbides
