本文的目的在于介绍用团粒法制备细WC—Co 球粒的实验研究结果。这种方法由三步组成:将 WC 和 Co 粉末混合料置于倾斜的转筒内制团,再冷压和烧结。此项研究工作采用的制团设备如图1所
The purpose of this paper is to introduce the experimental results of the fine WC-Co pellets prepared by the pellet method. This method consists of three steps: placing the WC and Co powder mix in a tilted tumbler to form a pellet, then cold pressing and sintering. The system of equipment used in this research is shown in Figure 1
