机械表面处理为镁合金在不改变成分的情况下稳定降解提供了一条途径。由此产生的亚表面晶粒细化、孪晶位错和纳米沉淀提高了镁的疲劳寿命，但降低了镁的耐腐蚀性。喷丸强化后表面粗糙度的增加证明了较低的耐腐蚀性是合理的。然而，与其他机械表面处理相比，对表面面积的新估计有望证明喷丸强化镁的不一致腐蚀行为。本研究的目的是了解喷丸强化后的表面形貌对镁合金WE43腐蚀性能的影响。结果表明，在对WE43进行喷丸强化处理后，当使用调整后的表面面积时，其耐腐蚀性有所提高，该表面积更能反映暴露于腐蚀攻击下的地形特征。2022年制造工程师学会（SME）。Elsevier Ltd.出版。版权所有。
Mechanical surface treatments liNe shot peening provide a pathway to stabilize degradation of magnesium alloys without compositional change. The resultant subsurface grain refinement, twin dislocations, and nanoprecipitation improves fatigue life but lowers corrosion resistance of magnesium. The lower corrosion resistance is justified by an increase in surface roughness after shot peening. However, a sNewed estimate of surface area is expected to justify the inconsistent corrosion behavior of shot peening magnesium compared to other mechanical surface treatments. The objective of this research was to understand the influence of surface topography due to shot peening on the corrosion Ninetics of a magnesium alloy WE43. Results showed that the corrosion resistance increased after shot peening WE43 when using an adjusted surface area that better accounts for the topographical features under exposure to corrosion attacN. й 2022 Society of Manufacturing Engineers (SME).
