Реферат:	eng: In the present work, rutile powders containing additions of metallic silver (2.5vol.%) were detonation sprayed in a reducing atmosphere formed by gaseous detonation products of the C 2H 2+1.05O 2 mixture. The initial volume of the C 2H 2+1.05O 2 mixture - explosive charge - used for a detonation pulse was computer-controlled as the fraction of the barrel volume filled with the mixture. Using a previously developed model of the detonation process, the particle temperatures and velocities were calculated to explain the observed phase and microstructure development in the coatings. With increasing explosive charge, the temperature of the sprayed particles increased and rutile was partially reduced to oxygen-deficient TiO 2-x and then to Ti 3O 5. When the melting temperature of rutile was not reached, the coatings were porous; semi-molten particles formed denser coatings obtained with higher spraying efficiency. Silver inclusions in the titanium oxide matrix experienced melting and substantial overheating, but remained well preserved in the coatings. © 2011 Elsevier Ltd.
