MULTICRITERION ASSESSMENT OF WEAR RESISTANCE OF Fe–Mn–C–B EUTECTIC COATINGS ALLOYED WITH Si, Ni, AND Cr

Abstract

The results of tribological studies of Fe–Mn–C–B eutectic coatings alloyed with Si, Ni, and Cr are presented. The coatings are produced by gas metal arc welding with use of powder wires (2.4 mm in diameter). Multicriterion assessment is used to analyze the tribological properties of the coatings and determine the most wear-resistant coating. This assessment involves first a search of Pareto optimum solutions and then compromise solutions with use of the Chebyshev norm. This approach allows choosing the coating that shows the highest abrasive wear resistance among the six eutectic materials under study at specific loading varying from 3 to 15 МPа.
