Abstract

The cold gas dynamic spray process is a manufacturing process strategically designed
for coatings. The conditions for the deposition of materials to form coatings have
evolved over several decades. Copper and copper-based cold spray coatings are
an interesting field for investigation, as it has substantial commercial demand and
acceptance. Several important works have already been performed in this regard that
shows the immense popularity of its applications in power industries. Cold gas dynamic
spray, being an economic process, can produce coatings with superior quality and low
oxidation. In this paper, a particular focus has been given to copper-based cold spray
coatings along with their deposition parameters. The various mechanical, electrical,
corrosion, and tribological properties of these copper-based cold spray coatings are
commendable and economically lucrative. A good amount of experimental data has
