摘要：

为了研究新型数控机床齿轮材料Fe-Ni-Cu-C-Mo-V合金粉末锻造的可行性以及探讨始锻温度对齿轮材料耐磨损性能和耐腐蚀性能的影响。采用不同的始锻温度进行了齿轮材料的粉末锻造试验，并进行了耐磨损性能、耐腐蚀性能和密度的测试与分析。结果表明：采用粉末锻造方法，可以制备出综合性能较佳的齿轮材料。随着始锻温度从800 ℃增至1200 ℃，齿轮材料的磨损体积先减小后增大、腐蚀电位先正移后负移、密度先增大后减小，齿轮材料的耐磨损性能和耐腐蚀性能先提高后下降。与始锻温度为800 ℃时相比，始锻温度为1100 ℃时,粉末锻造的齿轮材料的磨损体积减小28.4%、腐蚀电位正移23.1%、密度增大7.0%。粉末锻造新型数控机床齿轮材料Fe-Ni-Cu-C-Mo-V合金的始锻温度优选为1100 ℃。

In order to study the feasibility of powder forging for new NC machine tool gear material Fe-Ni-Cu-C-Mo-V alloy and explore the influences of initial forging temperature on the wear and corrosion resistance properties for the gear material, the powder forging test of gear material was carried out at different initial forging temperatures, and the wear resistance property, corrosion resistance property and density were tested and analyzed. The results show that the gear material with better comprehensive properties can be prepared by powder forging method. When the initial forging temperature increases from 800 ℃ to 1200 ℃, the wear volume of gear material first decreases and then increases, the corrosion potential first moves positive and then negative, the density first increases and then decreases, and the wear and corrosion resistance properties of gear material first increase and then decrease. Compared with the initial forging temperature of 800 ℃, the wear volume of powder forged gear material at the initial forging temperature of 1100 ℃ is reduced by 28.4%, the corrosion potential moves positive by 23.1%, and the density increases by 7.0%. Thus, the initial forging temperature of powder forged new NC machine tool gear material Fe-Ni-Cu-C-Mo-V alloy is preferably at 1100 ℃.
