High boron iron-based wear-resistant alloy has the characteristics of high hardness and low price.Cladding on the surface of parts can effectively reduce wear.Boride is used to replace the carbide in traditional wear-resistant materials as a wear-resistant hard phase.Although it has good wear resistance,due to the brittleness of boride,the alloy has the disadvantage of insufficient toughness.In this paper,the classification and research progress of high boron iron-based wear-resistant alloys are reviewed.The wear resistance of hypoeutectic and hypereutectic high boron iron-based alloys and the improvement of alloy toughness by different processes are emphatically analyzed.The research of high boron iron-based wear-resistant alloys is prospected.
