Abstract

The article deals with methods for determining the hardness and microhardness, as well as the wear resistance of hardened samples and parts of machines obtained by casting in earthen forms. The composition, properties and microstructure of carbon steel grade 45 were studied. The optimal modes of heat treatment of the deep-barker of tillage machines and mechanisms have been determined and applied. The results of abrasive wear of cast steel samples before and after optimal heat treatment (hardening with subsequent tempering) are given. It is shown that optimal heat treatment increases the hardness and abrasive wear resistance of cast steel parts of machines by 2-3 times.
