Abstract
一个方法,与 La (NO3 ) 做 WC 3,生产 cemented,有稀土元素的碳化物被介绍。WC-9 (Co-75%Ni ) cemented 碳化物的机械性质和微观结构上的镧的效果被学习,钻实验的岩石被执行。试验性的结果证明两横向的破裂力量( TRS )和 WC-9 ( Co-75%Ni )稀土元素 cemented 碳化物的坚硬能匹配 WC-9Co cemented 碳化物的,当时La2O3/(公司+ Ni )比率0.3%,在 cemented 碳化物的 WC 谷物的反常生长能有效地被制止,在微观结构和wear 抵抗的谷物尺寸的同质被改进,它能对为采矿的 WC-9Co cemented 碳化物的可匹配。
