The properties of pure Cu, Ni and Ti cold spray coatings on mild steel substrates were examined. Samples were prepared using CGTTM Kinetics 3000 system varying gun temperatures from 200 to 600 °C and gun pressures from 10 to 30 bars with N2 as propelling gas. For these conditions, deposition efficiencies and critical velocities were characterized. In addition, the microstructural and mechanical properties of coatings were examined.
