本试验所用YG牌号硬质合金成分为(%):钨82,钴8,碳10。工序如下: (一) 制粉将合金加热氧化,然后投入去离子水中急冷粉碎,粉料磨细待用。(二) 氢气还原将氧化钨钴粉放入电阻炉中加热,通氢气还原,得钨、钴金属或低价氧化物。(三) 钨粉的制取将钨钴分离所得滤渣用盐 YG grade cemented carbide used in this test composition (%): Tungsten 82, cobalt 8, carbon 10. Processes are as follows: (A) milling the alloy heated oxidation, and then put into deionized water quench crushed, fine powder to be used. (B) hydrogen reduction Tungsten oxide cobalt powder into the resistance furnace heating, hydrogen reduction, have tungsten, cobalt metal or sub oxide. (C) Preparation of tungsten powder will be separated from the tungsten and cobalt residue with salt
