Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT This study elucidates the oxidation mechanisms governing Y/Hf‐doped AlCoCrFeNiTi high‐entropy alloys (HEAs) and reveals the pivotal role of fabrication processes in dictating high‐temperature oxidation behavior. We demonstrate that casting and spark plasma sintering (SPS) promote Y/Hf segregation, resulting in heterogeneous oxide formation and

Gongye shui chuli, 2020 针对电化学除垢技术效率低的问题，系统研究了高效复合网状阴极电化学除垢的机理。研究结果表明：屏蔽效应使得外层网上的析氢反应强于内层网上的析氢反应，沉积反应优先发生在外层网。快速析出的氢气泡作为软模板，不仅可使水垢以枝晶形态生长，还使得外层网具有自清洁作用，大大延长了阴极的失活时间。同时，内层网增加了阴极的反应面积，在提高除垢速率的同时降低了阴极面积需求。
