| Abstract: | A general technical was used to produce WC-12wt%Co alloy with plate-like shape WC grains in this paper, it was prepared using common W powder ,Co powder and graphite powder as raw materials. The study shows that it is help to form plate-like shape WC in alloy using plate-like shape W as raw materials ,increasing the sintering temperature and prolonging sintefing times. |
