Аннотация

Microstructure development of TiB2-Cu nanocomposite powders during cold and detonation spraying was investigated. The powders were produced by self-propagating high-temperature synthesis (SHS) followed by mechanical milling. A computer model was developed to calculate the temperatures during detonation spraying. The change in the nanostructure of the powders during spraying was studied: due to low temperatures in cold spraying the size of TiB2 particles in the coatings was well retained, in detonation sprayed coatings the growth of the particles was observed, the mode of spraying affecting the microstructure and the size of the particles.
