Abstract：

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 ℃.
