| titleOfInvention | Hard alloy Co-based alloy powder and preparation method thereof |
| abstract | The present invention relates to hard alloy Co-based alloy powder and preparation method thereof.Specifically, a kind of preparation method of the Co-based alloy powder prepared for hard alloy is disclosed, it includes：By soluble cobalt and one or more it can suppress the transition element soluble salt that hard alloy crystal grain grows up and be dissolved in distilled water to be configured to 0.5 2.0mol/L mixing salt solutions；Precipitating reagent is added in distilled water and is configured to 0.8 2.5mol/L solution；Two kinds of solution are added in reaction vessel and reacted to generate cobalt-based complex salt；Separation of solid and liquid is carried out to the sediment comprising cobalt-based complex salt and is cleaned to cobalt-based complex salt；And calcined cobalt-based complex salt, micron order is obtained after decomposition（Containing nanoscale）Co-based alloy powder.The Co-based alloy powder is in below sub-micron for preparing crystallite dimension（Comprising but be not limited only to nano-scale range）Hard alloy. |
