前驱物颗粒形貌对钨钴合金粉形貌的影响

Influence of morphology of precursor particles on W-Co powder morphology

研究了不同前驱物(草酸钴粉末、氧化钴粉末)颗粒形貌对钨钴合金粉形貌的影响。采用粉末共还原的方法制备钨钴合金粉末,通过SEM观察制备前后各种粉末形貌,讨论了钨钴合金粉形貌与不同前驱物(草酸钴粉末、氧化钴粉末)颗粒形貌之间的关系。

Study is made on the preparation method, particle morphology of powder blue and cobalt oxalate, which are used as precursor for reduction of W-Co alloy powder. The morphology were analyzed by SEM. Discussion is made on the relation-ship between the morphology of W-Co alloy powder particle and precursor.
