摘要

目的探究超声喷丸角度对AZ31B镁合金耐蚀性的影响机理。方法采用不同的超声喷丸角度对AZ31B镁合金进行了超声喷丸处理,研究了不同喷丸角度对AZ31B镁合金耐蚀性能的影响规律,并通过表征材料的微观组织及表面形貌,分析了喷丸角度对AZ31B镁合金耐蚀性的影响机制。结果改变超声喷丸角度可以有效改善材料表层的宏观形貌,使材料表层形貌更加平整。超声喷丸角度的降低减小了丸粒对材料表层的冲击作用,缓解了传统超声喷丸在材料表层造成的高应力状态。90°、45°、30°超声喷丸后,试样的稳态开路电势分别为-1.595、-1.552、-1.538 V。结论 3种喷丸角度的处理方式按镁合金开路电位从大到小的顺序依次是30°超声喷丸、45°超声喷丸、90°超声喷丸。喷丸角度的增加有效提高了材料的耐蚀性能,这为进一步提高AZ31B镁合金耐蚀性提供了新方法和借鉴。

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.
