In this study, an attempt has been made to produce thick Cu coatings on carbon steel substrate using Cold Gas Dynamic Spray technology. Severe plastic deformation (SPD) involves very large strains, which are imposed on a specimen without introducing any significant changes in it’s  dimensions.  From this point of view, the Cold Gas Dynamic Spray (CS)  can be considered as an SPD  process, in which a very large plastic strain is imposed on  the interface due to the impact of particles accelerated to supersonic velocities. The influence of Cold Spray parameters on the Cu coating microstructure  and properties was determined.  The nano-structured interface of Cu coatings/Carbon steel substrate  exhibit very high adhesion strength and good mechanical properties, which makes the CS technology  attractive for producing copper clad parts. The SPD related features of the CS process is also discussed.
