Abstract

The paper discusses the production and properties of wear-resistant eutectic coatings based on the Fe-Mn-C-B-Si-Ni-Cr system. The coatings are obtained by gas metal arc (GMA) welding in a protective argon atmosphere with use of powder wires (2.4 mm in diam-eter). After wear-resistance tests, the phase composition, microstructure, distribution of ele-ments, and nanohardness of eutectic coatings are examined. The powder wires are used for strengthening and regeneration of knives used in equipment for shredding of tires.
