Abstract

The work aims to investigate the effect mechanism of ultrasonic blasting angles on the corrosion resistance of AZ31B magnesium alloy. AZ31B Mg alloy was treated by different ultrasonic blasting angles. The effect of different blasting angles on the corrosion resistance of AZ31B Mg alloy was investigated and the mechanism of blasting angles on the corrosion resistance was also analyzed by characterizing the microstructure and surface morphology of the AZ31B Mg alloy. Changing the ultrasonic blasting angle could effectively improve the macroscopic morphology of the surface layer of the material and make the surface morphology of the material more flat. The reduction of the ultrasonic blasting angle decreased the impact of the pellets on the surface layer of the material, thus relieving the high stress state of the material surface layer caused by the large-angle ultrasonic blasting. After ultrasonic blasting at 90°, 45° and 30°, the steady-state open-circuit potential of specimens was -1.595 V, -1.552 V and -1.538 V, respectively. The magnitude of the open-circuit potential of the Mg alloy treated at the three ultrasonic blasting angles is in the following order of 30° ultrasonic blasting, 45° ultrasonic blasting, 90° ultrasonic blasting. The increase of ultrasonic blasting angle effectively improves the corrosion resistance of the material, which provides a new method and reference for improving the corrosion resistance of AZ31B Mg alloy further.
