Description
Nanodisperse powders (NDP) of carbonitrides of IV-VI group transition metals (for example, TiCxN1-x, NbCxN1-x, Cr3C1,6N0,4), their hard alloys (for example, TixNb1-xCyN1-y) and mixtures (for example, TiCxN1-x-Cr3C1,6N-0,4) with the medium particle size of 50 - 200 nm have been prepared by the method of plasmachemical synthesis. Due to the dynamic conditions of synthesis (starting products evaporation or decomposition, mixing and condensation of the end product is lasting for some tenths of second) the products is formed in a form of NDP, mainly as a monocrystals with a great concentration of the crystallic lattice defects. This determined high chemical activity of these powders, including increased sintering rate and decreased sintering temperature. Some examples of use of such powders are given. (author)
