REVIEW OF THE INFLUENCE OF THE MICROSTRUCTURE OF STEELS ON THEIR ABRASIVE WEAR

Abstract

Steels are still the most widely used material in the agricultural machinery industry. Tillage machinery implements are the parts most exposed to abrasive environments. Steel grades are used that are characterized by high wear resistance for the manufacture of such parts. This property largely depends on the microstructure of the steel, which is most often formed during heat treatment. The article presents a review of the relationship between microstructure and their resistance to abrasive wear of medium carbon steels, most often used for the manufacture of tillage machinery parts due to their sufficiently good mechanical properties and relatively low cost compatibility, and the influence of the main heat treatment parameters on the formation of the microstructure with the highest wear resistance.
