METHOD FOR PRODUCING A HARD METAL PROJECTION |
| 摘要 |
<p>A hard metal grade powder is produced from hard material, metal binder, and non-water-soluble pressing aid components, by forming a slurry containing the components and pure water as a liquid phase and then drying the slurry. Here, the hard material and metal binder components are first milled in water, to form a slurry. Then the pressing aid components are added to the slurry in the form of an emulsion produced with the aid of an emulsifier with the addition of water.</p> |
