摘　　要：采用不同的高频淬火和回火温度对钒钛改性汽车凸轮轴进行了热处理,并对其磨损性能和冲击性能进行了测试与分析。结果表明：当高频淬火温度从850℃逐渐增大到950℃或者回火温度从175℃逐渐增大到275℃时,凸轮轴磨损性能和冲击性能均先提高后下降。凸轮轴的高频淬火温度和回火温度分别优选为925℃、250℃。The automobile camshaft modified by vanadium and titanium was heat-treated by using different high frequency quenching and tempering temperatures. And the wear resistance and impact property was tested and analyzed. The results show that when the high frequency quenching temperature increases from 850 ℃ to 950 ℃ or tempering temperature from 175 ℃ to 275 ℃, both wear resistance and impact property of the camshaft firstly increase and then decrease. The optimized high frequency quenching and tempering temperatures are 925 ℃ and 250 ℃, respectively.
