碳化钨广泛用于生产切削工具和零件，具有非常好的耐磨性。众所周知，烧结碳化物的性能与碳化物颗粒尺寸密切相关。碳化钨生产是一个费力的过程，其中总是包括铣削步骤。本文旨在研究采用机械合金化（MA）方法通过三氧化钨渗碳来制造碳化钨，从而将这一过程浓缩为一步。使用 Frich 行星式研磨机进行实验测试，研磨 30 小时后观察到三氧化钨完全转化为碳化物。合成 WC 的 D50 平均值为 6.73 ± 0.62 μm。
Tungsten carbide is widely used in the production of cutting tools and parts with very good resistance to wear. It is well known that the properties of sintered carbides are closely related to the carbide particles size. Tungsten carbide production is a laborious process, which always includes a milling step. This article aims to study the manufacturing of tungsten carbide by carburizing tungsten trioxide using mechanical alloying (MA) method, thus concentrating the process in one step. Experimental tests were performed with a Fritch planetary mill and complete conversion of tungsten trioxide in carbide was observed after 30 h of milling. The average value of D50 for the synthetized WC is 6.73 ± 0.62 μm.
