摘　　要：本实验系统地研究了碳化钨粗颗细粒搭配对WC—10%合金的力学性能与组织结构的影响.优质碳化钨粉,通过空气分级的方法获得三种不同粒度级别的碳化钨.不同粒度级别的碳化钨,以适当的比例搭配和钴粉混合.获得具有“双重晶粒结构”的硬质合金,在凿岩试验中取得了良好的结果.The influence of the matching of coarse and fine WC powdres on the mechanical properties and microstructures of WC-10%Co cemented carbides has been systenatically studied in this paperthree groups of fine-quality WC powders classified by air according to their particle size ,were matched in suitable proportion and these mixed with cobalt powder The resultant cemented carbide with 'double grain structure 'has been proved to be successful in rock-drilling experiment
