| 英文摘要 | To promote the application of magnesium alloys for reducing the weight of the engineering components, improvement of their wear and corrosion resistance by coating processes is a necessity. In the present study, cold sprayed nano WC-17Co coatings have been deposited on commercial AZ80 magnesium alloy at different nozzle traverse speeds. WC-17Co coating exhibits a highly dense structure and well bonds with the magnesium alloy substrate when the traverse speed is selected as 80 and 40 mm/s. The C40 coating that is prepared at 40 mm/s possesses the highest microhardness and fracture toughness. The ball-on-disk wear test indicates that WC-17Co coating can significantly improve the wear resistance of magnesium alloy. The wear rate of C40 coating is 8.2 x 10(-7) mm(3) N-1 m(-1), while magnesium alloy exhibits very high wear rate of 6.8 x 10(-4) mm(3) N-1 m(-1). Meanwhile, WC-17Co coating reduces the corrosion current density of magnesium alloy and C40 coating also possesses more excellent corrosion resistance than that of C80 coating. Thus, with appropriate traverse speed, high quality nano WC-17Co coating can be prepared and the wear and corrosion resistance of magnesium alloy substrate can be greatly improved by this cold sprayed coating. |
