Evolution of dispersion of high temperature chromium compounds

[摘要] Chromium compound - boride Cr3B2and carbide Cr3C2are hard, wear-resistant, chemically inert materials, demanded for production of protective coatings of metals and cermets as components and alloying additives of tungsten free solid alloys. Future prospects for expansion of boride and chromium carbide usage are related to their production in the form of nanopowders. The researches into change of the particles shape and size of high-temperature chromium compounds in the conditions of plasma flow were carried out. There is coarsening of boride and carbonitride particles of nanoscale level at the reduction in the linear velocity of their growth.
