摘要
研究了利用高能球磨法制备纳米WC Co混合粉末的可能性 ,以及球磨时间和WC Co纳米粉末粒度的关系。结果表明 :随着球磨时间的延长 ,WC Co纳米粉末的粒度逐渐变小 ,当球磨时间超过 30h后获得了粒度为 10 0nm以下的WC Co纳米粉末。
A preliminary study on the possibility of preparing nanostructured WC Co powder by ball milling has been performed regarding to the relationship between the grain size of the powder and the milling time. The results show that the grain size of the powder decreases with the increase of milling time. The method can produce nanostructured WC Co powder with grain size below 100 nm when the milling time exceeds 30 h.
