摘要
中细WC粉末在高档可转位刀片、球齿、耐磨零件中广泛应用。随着粉末制备进一步产业升级,对中细WC粉末的质量提出了更高的要求。研究以1.8～2.0μm的钨粉为原料,采用3种不同的碳化设备,在不同工艺条件下,制备出3种中细碳化钨粉末。通过采用粒度分布、扫描电镜图、合金金相组织图进行比较分析,确定适合耐磨零件的中细WC粉末的最优碳化工艺：使用碳化设备B,十四管炉制备FSSS粒度1.8～2.0μm的钨粉,碳化温度为1 400～1 500℃。
The middle and fine grain WC powder is widely used in advanced movable blades, sophisticated spherical shape bits and wear-resistant parts. The industrial upgrading requires a higher quality of middle and fine grain WC powder. By using different carbonization processes, three middle and fine grain WC powders were prepared out of tungsten powder with particle size of 1.8 -2.0 μm. The analysis of the size distribution, scanning electron microscope and metallographic structure led to the optimal carbonization process, using the carbonization equipment B, the Fsss grain size 1.8 -2.0 μm tungsten powder is prepared by fourteen tube furnace, and the carbonization temperature is 1 400-1 500.
