Cobalt Powder performance analysis and detection technology. - By: mhcmp

Cobalt is the world's scarce strategic metal cobalt powder is used for super-hard alloy material (such as carbide and diamond tools) one of the key raw material, its performance determines the bonding properties of super-hard alloy materials, strength and toughness, on the use of super-hard alloy material properties is essential.

Now the production of super-hard alloy materials used in the ordinary cobalt powder, because its structure is hexagonal, and the coarse grain size, alloying elements unreasonable, morphology is dendritic and other issues, can not meet the high-performance super-hard alloy material necessary requirements. Therefore, this research project on the development of high-performance super-hard alloy materials is extremely important. To improve the general performance of cobalt powder, to change the organizational structure of its powder. Principles of the material, changing the material structure of the best ways, one through grain refinement, the second is a reasonable use of alloying elements added. Cobalt powder for general irrational structure of this key issue, this project is to co-precipitation method by chemical, physical and chemical thermal chemical reduction method, morphology, particle size, composition more reasonable Nanocrystalline composite reinforcement cobalt powder, and the use of advanced detection method of the physical and chemical properties of the powder. The development of this technology can be effectively reduced the use of cobalt to provide the service life of super-hard materials including cobalt, cobalt save resources, improve Guangdong Province, electronics, automotive precision machining level. The main content of project:

(1) nano-crystalline reinforcement of composite cobalt powder composition and structure design and optimization;

(2) nano-crystalline reinforcement of composite cobalt powder precursor chemical co-precipitation method and physical chemical process of heat (such as: chemical precipitation and physical heat of chemical reaction temperature, capacity, time, speed, etc.);

(3) optimization of composite cobalt powder precursor powder properties (such as: composition, structure, morphology, particle size, size distribution, mobility, Poisson ratio, etc.);

(4) nano-crystalline cobalt powder composite reinforcement technology of chemical reduction (such as: reduction temperature, flow, reducing the time, loaded boat traffic, speed reduction, etc.);

(5) nano-crystalline reinforcement of composite cobalt powder properties (such as: composition, structure, morphology, particle size, size distribution, mobility, Poisson ratio, etc.).
