This work presents the results of research aimed at creating a new type of composite powder for spraying coatings with increased hardness on the details of wind turbines (wind turbine stands). The analysis of materials and technologies used for the synthesis. The conditions for the mechanochemical synthesis of a composite powder based on the aluminum â silicon nitride system, the deposition of which allows the formation of a coating with a unique set of properties, are determined. The features of the formation of an additional strengthening phase in composite nanostructured powder are investigated. A complex of studies aimed at the definition of the technological chain "composition-structure-technology-properties." The prospect of further research and the use of the developed materials was determined. The work was carried out in the framework of the Russia-South-Eastern Finland 2014-2020 Cross-Border Cooperation Program, the project "Energy-efficient systems based on renewable energy sources for Arctic conditions" (EFREA). |
