Structure and Properties of Sintered Iron–Boron–Carbon Alloys with Different Carbon Contents

Abstract

The study of the structure and mechanical and tribotechnical characteristics of iron–boron–carbon alloys produced from a mixture of iron, boron carbide, and graphite powders by single pressing and sintering is used to examine heterophase wear-resistant materials containing from 0.8 to 2.4% boron and from 0.7 to 1.6% fixed carbon. The wear resistance of the developed material depends on the ratios of boron and carbon in them and on their total content and substantially exceeds the wear resistance of ShKh15 steel chosen as a standard sample.
