摘要: Cold spray (CS) is an emerging revolutionary technology for deposition of metal or composite powders at a low temperature. High quality deposits can be produced without heating related defects, such as oxidation, phase transformation and residual tensile stress due to the shrinkage during fast cooling. The present contribution demonstrates state art CS process. Since nozzle key component in equipment prompt efficiency particle acceleration, progress its design summarized. Major issues regarding successful adhesion particles corresponding interaction with substrates existing are discussed, terms numerical simulation experimental observation. Current implemented applications presented, potential industrial discussed. Keywords: cold spray; coatings; rapid manufacturing; impact; bonding mechanism;
