THE TECHNOLOGY OF OBTAINING POWDERS USED IN THE PRODUCTION OF SOLID ALLOYS

The scientific and practical study on contemporary technologies and methods for generating powders (cobalt and tungsten carbide)-the building blocks of tungsten carbide-cobalt-based solid alloys that are widely utilized in the mining and metallurgy industries-is presented in this article. In the course of research, it was studied how to obtain pure cobalt powder from cobalt oxide and pure tungsten carbide powder from tungsten oxide. Cobalt is a binder that affects the hardness, brittleness, density, bending strength, tempering temperature and abrasive wear resistance of hard alloys. The binder is required to be sufficiently flexurally strong, tough and resistant to abrasive wear under operational conditions and this requires obtaining pure cobalt powder. Today, the main raw materials for the production of hard alloys at the “SPA to produce rare metals and the hard alloys” under “Almalyk MMC” JSC are brought from the waste cakes in the territory of the SPA and the Ingichka mine located in the Samarkand region and hydrometallurgically processed tungsten oxide takes up to (WO3).To solve this task, the electron microscopic method was used during the research. All studies were performed on a JSM-IT200 (JEOL, Japan) scanning electron microscope at the “Uzbekistan-Japan Youth Innovation Center”.
