The synergistic influences of particle stimulated nucleation (PSN)-assisted dynamic recrystallisation (DRX), second-phase particles and texture on corrosion behaviour of hard-plate hot forged Mg-Zn-Ca-Mn alloy are studied in Kirkland’s bio-corrosion medium. The particle-matrix interfaces and grain boundaries are more anodic and act as effective sites for corrosion initiation and insoluble corrosion product layer formation. Consequently, the uniform and compact product layer is formed in the specimen with higher DRX fraction, uniform particle distribution and smaller deformed grains. The uniform corrosion product layer and higher basal texture intensity lowered the pH change, hydrogen evolution and corrosion rate during the long-term immersion test.

显微组织演变和织构变化对硬板热锻Mg-4Zn-0.5Ca-0.16Mn (wt. %)合金体外生物腐蚀行为的影响

在柯克兰生物腐蚀介质中研究了粒子受激成核 (PSN) 辅助动态再结晶 (DRX)、第二相粒子和织构对硬板热锻 Mg-Zn-Ca-Mn 合金腐蚀行为的协同影响。颗粒-基体界面和晶界更加阳极化，并作为腐蚀起始和不溶性腐蚀产物层形成的有效位点。因此，在试样中形成了均匀致密的产品层，具有较高的 DRX 分数，均匀的颗粒分布和较小的变形晶粒。均匀的腐蚀产物层和较高的基底织构强度降低了长期浸泡试验过程中的 pH 变化、析氢和腐蚀速率。
