摘要: 在钻头用W6Mo5Cr4Vx高速钢中添加了不同含量的合金元素钒，并进行了显微组织、耐磨损和耐腐蚀性能的测试与分析。结果表明：添加钒有助于提高高速钢的耐磨损和耐腐蚀性能，随钒含量从0增至5%，钢的耐磨损和耐腐蚀性能均先提高后下降。钢中钒含量优选为3%。与不添加钒相比，W6Mo5Cr4Vx（x=3）高速钢的磨损体积减小5.2×10−3 mm3、腐蚀电位正移57 mV。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.
