摘要
以偏钨酸铵、硝酸钴、氨水、炭黑为原材料,采用共沉淀—直接碳化原位合成法制备了WC-Co复合粉。研究了前驱体的制备过程,考察了还原碳化工艺参数对所得产物物相的影响。利用SEM、XRD分析方法对粉末样品的微观形貌和物相组成进行了表征,并对还原碳化过程进行了探讨。结果表明:采用共沉淀法制备的前驱体粉末为许多小颗粒团聚而成的大颗粒,小颗粒均匀细小,粒径在500 nm左右,前驱体粉末经1 000℃还原碳化可以得到物相纯净的WC-Co复合粉,WC-Co复合粉分散性好,粒度分布均匀。
Using ammonium metatungstate, cobalt nitrate, ammonium hydroxide, and carbon black as the raw materials, the WC-Co composite powder was fabricated by coprecipitation and direct carbonized in situ synthesized method. The synthesis process of precursor and the effects of reduction carbonization process parameters on phase of product were studied. The powder morphology, phase compositions of WC-Co composite powder were characterized by SEM, XRD, and the reduction carbonization process was studied. The results show that each precursor powder has some larger particles, which make up by lots of minute particles, and the diameter is about 500 nm. Precursor powders are carbonized completely at 1 000 ℃, then prepared composite powder has WC and Co phases, which have good dispersion and uniform distribution.
