Abstract The effect of coupling of unalloyed Mg and Mg-alloys (AZ91 and WE43) with Ti6Al4V alloy on corrosion and degradation behaviours of produced composites has been investigated in simulated body fluid (SBF) by hydrogen evolution, and surface and electrochemical characterization techniques. Combining of unalloyed Mg with Ti6Al4V intensified galvanic corrosion and catastrophic failure occurred by initiation of microcracks formed by sudden hydrogen gas evolution. In contrast to other composites, Ti6Al4V-AZ91 composites, containing new TiAl3 interface layer formed during composite production, preserved their mechanical integrities due to lowest corrosion and degradation rate of AZ91 alloy.

Ti6Al4V-Mg/Mg-Alloy 复合材料的腐蚀行为

摘要 通过析氢、表面和电化学表征技术，在模拟体液 (SBF) 中研究了非合金镁和镁合金（AZ91 和 WE43）与 Ti6Al4V 合金的耦合对制备的复合材料的腐蚀和降解行为的影响。非合金 Mg 与 Ti6Al4V 的结合加剧了电偶腐蚀和灾难性故障，这是由突然的氢气释放形成的微裂纹引发的。与其他复合材料相比，Ti6Al4V-AZ91 复合材料包含在复合材料生产过程中形成的新 TiAl3 界面层，由于 AZ91 合金的腐蚀和降解率最低，因此保持了其机械完整性。
