Abstract

Abstract

In this paper, different content of vanadium was added to W6Mo5Cr4Vx high speed steel for bit, and the microstructure, wear resistance and corrosion resistance were tested and analyzed. The results show that the addition of vanadium can improve the wear resistance and corrosion resistance of high speed steel. With the increase of vanadium content from 0 to 5%, the wear resistance and corrosion resistance of steel increase firstly and then decrease. The optimized vanadium content in experimental steel is 3%. Compared the steel without vanadium addition, the wear volume of W6Mo5Cr4Vx (x=3) high speed steel decreases by 5.2×10⁻³ mm³, and the corrosion potential shifts positively by 57 mV.
