摘要
本文采用正交试验法,对高能行星球磨制备纳米WC-38%MgO(质量分数)复合粉末的工艺参数进行了优化研究。试验表明,当磨球直径为10mm、球磨机转速为350r/min、球料比为6:1时,最有利于WC-MgO复合粉末的细化。当球磨罐中装料量(mp=100g)一定时,理论计算和球磨实验得出的最佳球料比均为6:1。
In this paper, an orthogonal experiment was introduced to optimize the technological parameters of high energy planetary ball milling on nano-structured WC-38%MgO （mass fraction） composite. The result showed that it is of benefit to fining of WC-MgO composite that the ratio of ball-to-powder is 6：1, ball diameter is 10mm, and the milling speed is 350r/min. The result also showed that the optimum ball-to-powder mass ratio is 6：1 which was based on the theoretical derivation and milling orthogonal experimental analysis, if the mass of samples with milling fixed at 100 grams in every milling vial.
