研究了用直流电弧等离子体法制备 Ni、Cu超微粉时 ,在原材料中加入高熔点金属 W、Mo后 ,对超微粉产率的影响 .结果表明 ,Ni、Cu超微粉的产率有较大幅度提高 ,并且超微粉中几乎不含有 W和 Mo.探讨了 W、Mo提高超微粉产率的原因 .
The effects of high melting point metal W and Mo on the yield of ultrafine powder were studied when DCP plasma was used to prepare Ni and Cu ultrafine powders.The results showed that the yields of ultrafine Ni and Cu powders were larger Amplitude increased, and the ultrafine powder contains almost no W and Mo. W, Mo to improve the yield of ultrafine powder reason.
