On-Site Speaker (Planned) Yang Xiao
Abstract Scope Fe-Cr-Ni合金具有卓越的耐腐蚀性和抗氧化性，广泛应用于极端环境下的精密仪器零件。其工业应用受限于长的制备周期和高昂成本。因此，本研究以Fe2O3、Cr2O3及NiO为原料，在673 K至1273 K的温度范围内进行了熔盐电解氧工艺的热力学分析，以制备Fe-Cr-Ni合金。 为制备Fe-Cr-Ni合金提供理论支持。结果显示，Fe2O3首先还原为Fe3O4，接着Ni还原，接着逐步还原Fe3O4逐步还原为Fe， 最终 Cr2O3 还原为 Cr。在电解氧化过程中，CaFe2O4、CaFe3O5以及CaCr2O4在Ca2+的影响下产生。最终，在电驱动力的作用下，它们被还原为元素形态，并相互扩散形成Fe-Cr-Ni合金。
