The cold gas spraying process is the most modern method of thermal spraying. The article presents the coating produced in this process from Cr3C2-25(Ni20Cr) powder on the Al 7075 alloy substrate. The properties of microstructure and mechanical properties of the deposited coating are also shown. The process parameters of the applied powder allowed to obtain coatings characterized by a consistent microstructure and negligible porosity.
