摘要

本研究考察了TiZrHfNb合金体系中6种二元合金对耐蚀性的协同效应。结论是，氧化物的类型和价态对氧化膜的稳定性影响最大，氧化物的电子构型直接影响氧化膜的稳定性。在合金成分中，Ti的抗溶出性最弱。含Zr/Hf的合金具有最快的氧化速率和再钝化速率。在重复溶解和再钝化循环过程中，Ti的存在导致钝化膜密度的下降，而Nb的存在则增强了钝化膜的稳定性。在较长的浸泡时间内，ZrHf合金的耐腐蚀性明显优于TiNb合金。

Synergistic effects of binary alloys of group components within multiple principal element alloys

This study investigates the synergistic effects of six binary alloys within the TiZrHfNb alloy system on corrosion resistance. The conclusion is that the type and valence state of oxides have the greatest influence, and the electronic configuration of oxides directly affects the stability of the oxide film. Among the alloy components, Ti exhibits the weakest resistance to dissolution. Alloys containing Zr/Hf exhibit the fastest oxidation rates and re-passivation rates. During repeated dissolution and re-passivation cycles, the presence of Ti leads to a deterioration in the density of the passivation film, while the presence of Nb enhances the stability of the passivation film. Over extended immersion periods, the corrosion resistance of ZrHf alloys significantly outperforms that of TiNb alloys.
