The types and distribution of hard phase have great influence on the wear resistance of hardfacing wear resistant steel plate . The complex eutectic and inter-metallic compound formed by alloy elements has a strengthening effect to backing plate, so as to improve the strength and toughness of the matrix, and protect it from indentation and fracture with its higher resistance to abrasive wear. A variety of hard phases in the matrix can prevent wear damages come from grinding materials, and improve the wear resistance of the material.

Moreover, different types of hard phases have different hardness and other properties, also have different effects on the wear resistance of hardfacing metal. Hard phase formed by W, V and C has high hardness, can also increase improve high temperature resistance of matrix.

Commonly, wear plate hardfacing layer has a high hardness, good toughness, also can obtain a high wear resistance when hard phase is dispersed distribution.
