Additive manufad (AM) magn alloys corrode rapidly due to tensile stress and coarse microstructures. Cyclically combining (hybridizing) additive manufacturing with interlayer ultrasonic peening was proposed as a solution to improve corrosion resistance of additive manufactured magnesium WE43 alloy through strengthening mechanisms and compressive residual stress. Applying interlayer peening work hardened discrete layers and formed a glocal integrity of regional grain refinement and subsurface compressive residual stress barriers. Tensile residual stress that typically accelerates corrosion decreased 90%. Results showed time-resolved control over corrosion was attainable by interlayer peening, and local corrosion within print cells decreased 57% with respect to as-printed WE43.

由于拉伸应力和粗糙的微观结构，添加剂制造 (AM) 镁合金会迅速腐蚀。建议将（混合）增材制造与层间超声喷丸循环结合，作为通过强化机制和压缩残余应力提高增材制造镁 WE43 合金耐腐蚀性的解决方案。应用层间喷丸硬化离散层并形成区域晶粒细化和次表面压缩残余应力障碍的全局完整性。通常会加速腐蚀的拉伸残余应力降低了 90%。结果表明，通过层间喷丸可以实现对腐蚀的时间分辨控制，并且相对于印刷的 WE43，印刷单元内的局部腐蚀降低了 57%。
