| Abstract: | 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. |
