一、概述从某种意义上讲,在硬质合金生产中,对于碳量控制的精度,是一个能否获得优质产品的带根本性的问题。我们从WC—Co系合金的相图(图1)中就可明显看到,由化学计量的WC和Co组成的合金位于WC—Co线上,因此在烧结温度下 I. Overview In a sense, in the production of cemented carbide, the accuracy of carbon control is a fundamental issue of whether or not to obtain quality products. As we can clearly see from the phase diagram of the WC-Co based alloy (Fig. 1), the alloy consisting of stoichiometric WC and Co is located on the WC-Co line and therefore at the sintering temperature
