Wear and Corrosion Properties of Cold Sprayed 420 Stainless Steel/WC-17Co Coating on Magnesium Alloy
420/WC-17Co coating was deposited on AZ80 magnesium alloy substrate by cold spraying technology. SEM was used to characterize the original powder morphology and coating microstructure. The microhardness and bonding strength of as-sprayed coating were tested by microhardness tester and universal mate...

| description | 420/WC-17Co coating was deposited on AZ80 magnesium alloy substrate by cold spraying technology. SEM was used to characterize the original powder morphology and coating microstructure. The microhardness and bonding strength of as-sprayed coating were tested by microhardness tester and universal material testing machine. Moreover, friction and wear property of the coating was also investigated by a ball-on-disk tribometer. Corrosion behaviours of coatings and magnesium alloy were characterized by electrochemical measurements. The results show that high quality 420/WC-17Co coating can be deposited on AZ80 magnesium alloy by cold spraying technology. The microhardness of cold sprayed 420/WC-17Co coating is (615 ± 62) HV, bonding strength is (57 ± 11) MPa and wear rate is only 3.3 × 10<sup>–6</sup> mm<sup>3</sup>·N·m. The wear resistance of cold sprayed 420/WC-17Co coating is improved by two orders of magnitude, and the corrosion current density is reduced by one order of magnitude than magnesium alloy substrate. In conclusion, the present research demonstrates that cold sprayed 420/WC-17Co coating can significantly improve the surface performance of magnesium alloy substrate without evident heating output. |
