摘　　要：对汽车弹簧用60Si2Mn合金钢中添加了微合金化元素Nb和V,并研究了其显微组织、力学性能、耐磨损性能和耐腐蚀性能。结果表明,添加微量合金元素Nb,尤其是复合添加微量合金元素Nb和V,可以提高60Si2Mn合金钢的力学性能、耐磨损性能和耐腐蚀性能。The micro alloying elements Nb and V were added into the alloy steel 60Si2Mn used in automobile spring, and the microstructure, mechanical properties, wear resistance and corrosion resistance were investigated. The results show that the mechanical ProPerties, wear resistance and corrosion resistance of the alloy steel 60Si2Mn are improved after adding trace elements Nb, especially compound adding trace elements Nb and V.
