This work aims to evaluate how varying feedstock powder particle sizes influences thermal, mechanical, and electrical properties in copper cold spray coatings.
Fabricated copper coatings using three different powder sizes (29.5 μm, 45.8 μm, and 69 μm) via cold spraying.
Evaluated mechanical, electrical, and microstructural properties of the coatings after optimizing gas pressure and temperature (4.9 MPa, 800 °C).
Analyzed the impact of particle-to-critical velocity ratio on the coatings' bonding and properties.
Coatings from 29.5 μm and 45.8 μm powders achieved over 90% IACS electrical conductivity and 6% predicted ductility.
Coatings from 69 μm powder showed 0% predicted ductility and 84% IACS, despite having similar η ratios.
Finer powders exhibited better interparticle bonding due to less interparticle oxide, enhancing coating properties.
