Article Preview

In this paper, to obtain hardfacing alloys with Anti-wearing,nine kinds of low-hydrogen type coating are designed with orthogonal optimization method and carbon, chromium, erbium and cerium are taken as four factors. The mechanical properties of each hardfacing layer are tested and the microstructure is analyzed. The optimal dosage of the four elements is found by R/S analysis method. There is no crack in continuous surfacing with the electrode prepared with optimal formula, the wear resistance of the corresponding hardfacing layer is good while the hardness reach to 57.9HRC, the microstructure is martensite, a small amount residual austenite and dispersed carbide.
