INVESTIGATION OF MODIFIER COMPOSITION TO IMPROVE WEAR RESISTANCE DURING THE MELTING OF WHITE CAST IRON

Abstract

White cast iron is widely used in wear-intensive applications due to its high hardness, but its brittleness limits performance in many industrial settings. This research investigates the effect of various modifiers—such as titanium (Ti), vanadium (V), and rare-earth metals (REMs)—on the microstructure and wear resistance of white cast iron during the melting process. The study includes melting tests, microstructural analysis, and tribological testing to determine the effectiveness of each modifier composition. Results show that Ti and V act as effective carbide stabilizers and grain refiners, while REMs enhance the uniformity of carbide distribution, leading to a notable increase in wear resistance.
