| Abstract: |
| Objective To improve the wear resistance and corrosion resistance of AZ31 magnesium alloy. Methods Ti film was successfully deposited on the surface of AZ31 using magnetron sputtering technology. The morphology and component of the interface of the film and the substrate were studied by scan electronic microscopy (SEM) and the binding energy of the film and the substrate was analyzed. The wear resistances of the blank magnesium alloy and the titanized samples were contrastively analyzed by the friction and wear test, and the corrosion resistances of the blank magnesium alloy and the titanized samples were contrastively analyzed by the electronic-chemical workstation. Results The film layer was compact and uniform, and bound well with the substrate. The friction coefficient and wear weight-loss rate declined. The corrosion potential shifted by +430 mV to the positive direction, and the corrosion current density decreased from 10. 83 mA/ cm2 to 2. 62×10-7 mA/ cm2 after the magnesium alloy was plated with Ti film. Conclusion The wear resistance and corrosion resistance of AZ31 magnesium alloy were improved by magnetron sputtering Ti. |
