Abrasive wear resistance of boronized carbon and low-alloy steels

In this study, the abrasive wear resistance of previously boronized 1020, 1045, 4140 and 4340 steels were determined. The boronizing treatments were performed in a mixture of dried borax and SiC at temperatures of 1223, 1273 and 1323 K, during 2, 4 and 8 h. On the surface of each steel, a monophase layer of Fe2B was obtained. The abrasive wear tests were performed by using a rubber-wheel apparatus (ASTM-G65 standard) operating with quartz sand and a force between wheel and specimen of 130 N. As a result, boronized 1020 steel exhibited the greatest abrasive wear resistance.
