Abstract:	An analytical model describing the deformation behavior of Copper during the cold spray process is presented. The model was developed on the microstructural basis where a particle being deformed is partitioned by two areas due to strain localization. The particle wall structure differs from that of the particle core because of strain localisation effects, and it is assumed the walls form a topologically continuous skeleton structure within which isolated islands of the particle core are encapsulated (Y. Estrin model). It was demonstrated that gradient plasticity model is capable of describing the experimentally observed trends and accounting for the strain localization during the particle impact and coating structure formation. The predictions of the model are in good agreement with experimental results reported by authors and other research groups.
