This study investigated effects of compounds of rare earth, LaNi 5 and CeO 2, on properties of cobalt-cemented tungsten carbide, diamond/carbide composite and diamond-tipped tungsten carbide insert for rock drilling under the active, low temperature sintering process which achieved by adding nickel and phosphorus into the mixed powders.

采用添加镍、磷的低温活化烧结工艺，分别用不同含量的稀土化合物LaNi5和CeO2 作为添加剂进行了试验，研究了其对硬质合金、金刚石硬质合金复合材料及由此构成的金刚石硬质合金复合凿岩柱齿性能的影响。

By composite addition of cobalt and calcium additives, the utilization and discharge potential of active material could be increased markedly.

物理添加的Co在活化充电时转变为导电性能良好的高价态CoOOH，这种于活性物质表面形成的CoOOH在放电过程中不能可逆地被还原，因而为活性物质与集流体之间以及活性物质颗粒之间提供了良好的电子通道，增加了导电性和有效反应位。

The recovered cobalt and manganese acetates can be reused for catalyst.

回收的醋酸钴和醋酸锰可以重复用作催化剂。

The extraction-crystallization method was used to recover cobalt and manganese acetates from the waste catalyst in the PTA production process .

以对苯二甲酸生产装置中排放的废催化剂为原料，采用萃取—结晶法回收其中的醋酸钴和醋酸锰。

The effct of operating conditions on the recovery of cobalt and manganese acetates was studied.The experimental results indicated that the recovery can arrive to 85%under the conditions of extraction temperature 80℃,extraction time 30—45min,liquid-solid ratio 9∶1 and crystallization temperature 5℃.

研究了操作条件对醋酸钴和醋酸锰回收率的影响，实验结果表明：在萃取温度80℃，萃取时间30～45min，液固比9∶1，结晶温度5℃，分三级萃取结晶的条件下，醋酸钴和醋酸锰的回收率达85%。

Fe-Co and Fe-Co particles have similar surface, which all consist of iron oxides rather than cobalt oxides. Borides can not be formed by the boron atoms from FeB alloy.

Fe-Co和Fe-Co超微粒子的表面结构很相似，都存在铁氧化物层，两种粒子表面都不存在钴氧化物。

The results show that a surface layer of stable cobalt borides of CoB, CoW2 B2 and CoW3B3 formed at 950 ℃ can effectively reduce the diffusion of Co to the surface of cemented carbide substrates when diamond films are deposited.

结果表明，基体经硼化预处理后表面形成CoB、CoW2 B2、CoW3B3相；当沉积温度为750~800 ℃，碳源浓度为3.3%时，薄膜表面形貌和生长织构随着沉积气压改变有明显的变化；硼化预处理后所得样品在1 500 N载荷下压痕表现出良好的附着性能，较二步法预处理更加有效地改善了膜基附着性能。
