摘　　要：采用不同的始锻温度、终锻温度和相同的锻压比对汽车轴头进行了试验,并进行了锻件的耐磨损性能和耐腐蚀性能的测试与分析。结果表明:在试验条件下,随始锻温度从980℃升高至1080℃,锻件的耐磨损性能和耐腐蚀性能均先提高后下降;随终锻温度从810℃升高至910℃,锻件的耐腐蚀性能先提高后下降。汽车轴头锻件的最佳工艺参数为:始锻温度1060℃、终锻温度890℃。Experiments of automobile axle head were carried out by using different initial forging temperatures, final forging temperatures and the same forging ratio. And the wear resistance and corrosion resistance of the forgings were tested and analyzed. The results show that：under test conditions, with initial forging temperature increasing from 980 ℃ to 1080 ℃, the wear resistance and corrosion resistance of the forgings firstly increase and then decrease; with finial forging temperature increasing from 810℃ to 910℃, the corrosion resistance of the forgings increases firstly and then decreases. The optimum technological parameters of the automobile axle head forgings are initial forging temperature of 1060℃ and final forging temperature of 890℃.
