High guality course-grained WC powder was produced by two-step carburization, which is possessed of character of high carbide carbon, low free carbon, unique phase, low impurities, uniform grain and sub-grain size,micro-defects-free and low dislocation density, and so as to prevent the bombard of WC powder.

采用二步碳化法制备出了优质粗晶WC粉末,该粉末具有化合碳高,游离碳低,为单一相,有害杂质含量少,晶粒均匀,晶内亚晶尺寸均匀,不含显微缺陷,较低的位错密度等特性,并解决了WC炸裂问题。
