On the search for producing intermetallics by diffusion reaction of cold spray bulk deposits

Popis výsledku v původním jazyce

Bi-metallic mixtures of elemental powders were deposited by cold spray technique in the form of bulk, self-supportive deposits with thickness of about 8 mm. The combinations used were Ti–Al, Fe–Al and Ni–Al in 1:1 at.% composition. Aluminides of titanium, iron and nickel draw substantial attention as materials with high application potential but also substantial production technology complications. Therefore the bi-metallic deposits were subjected to extensive series of annealing experiments in order to assess their behaviour during reaction diffusion synthesis of intermetallic phases. Short annealing for 2 h was used in 4.8 Argon protective atmosphere. Metastable and according to PD stable phases were identified alongside with heterogeneous diffusion artefacts (e.g. porosity). Temperatures ranging from 350 °C to 600 °C were used, which provided both solid-state reactions and diffusion in locally melted aluminium part of the bi-metallic deposit.
