The influence of particle impact temperature and size on adhesion of soft particle/hard substrate material in cold spray has been scarcely studied. While the relationship between particle impact conditions and particle/substrate bonding is commonly e

In order to provide a basis for future optimization and control of the cold spray process, we experimentally studied the impact of various factors on the ductility (% elongation) of copper coatings. For the current application, cold-sprayed copper is

In cold spray, high adhesion of soft materials on hard substrates is commonly achieved by using helium as the propelling gas. This is the case of copper coatings on steel where adhesion may reach values as high as 60 to 80 MPa (glue failure), however

Segregating the convoluted effects of particle size, impact temperature and velocity on deposition behavior and adhesion is of utmost interest to the cold spray field. The current study aims to associate the particle impact behavior and adhesion to i

Copper coatings produced by additive manufacturing techniques often present complex microstructural heterogeneity. Reducing microstructural heterogeneity is critical for promoting uniform mechanical and corrosion behavior. The current study examines

Cold-sprayed Cu coatings are known to have low ductility as the microstructure is composed of dynamically recrystallized fine grains, as well as larger crystals with high dislocation density. Annealing is typically employed to restore the ductility o

Quantitative X-Ray analysis was used to quantify the phase content generated by the High Velocity Oxygen Fuel (HVOF) process following the decarburisation of WC–Co coatings. Rietveld analysis was used to quantify the different phases present. Parti

Two types of commercial cermet powders WC-10Co-4Cr and nanostructured WC-12Co were modified by cladding thin layers of magnesium oxide onto their surface. The objective was to protect the WC phase from decarburization that regularly results from ther
