The paper gives investigation results on dependence of structure and phase composition of coatings produced by detonation spraying of the FeTi-B4C system powders upon the powder preparation method. Significant differences were detected in morphology and composition of coatings produced by spraying of conglomerated and sintered powders. It is shown that the process of new phase formation proceeds more intensively in spraying of the conglomerated powders.
Keywords: detonation spraying, phase composition, struc¬ture, conglomerated powder, sintered powder
