Abstract
As a result of the analysis of domestic and foreign literature, various methods for producing alloyed metal powders are studied, in particular atomization of alloys, acquisition with calcium hydride, thermal diffusion saturation, carbonyl processes, electrolysis and synthesis of complex oxides with further reduction. As a result, it was found that all researched methods, except for the synthesis and subsequent reduction of complex oxides, are not suitable for producing maraging steel powders. Atomization is suitable for producing pure metal powders, production with calcium hydride is impractical because maraging steels contain metals with a low affinity for oxygen ܨ ,݅ܰ ,݁ܥ և ܯ ,thermal diffusion saturation is not suitable due to the use of metal powder and the carbonyl process is rather complicated and difficult to implement. Comprehensive studies have shown that by combining the processes of synthesis (ferritation) and reduction of complex oxides in the best possible way, it is possible to develop an effective technology for production of alloyed powders, which will guarantee acquisition of an ultrapure chemical composition, required structure and properties.
