摘要

在LiCl-KCl熔盐中，采用酰胺钠（NaNH₂）作为氮源，在钛箔上制备了晶体氮化钛（TiN）层。纳米压痕测试显示了优异的机械性能，氮化表面的硬度达到了约20.6 GPa，比未处理的钛基板提高了四倍多。

Titanium Surface Nitriding by Sodium Amide in Molten Salts

A crystalline titanium nitride (TiN) layer on titanium foil is achieved using sodium amide (NaNH₂) as a nitrogen source in LiCl-KCl molten salts. Nanoindentation testing revealed exceptional mechanical properties, with the nitrided surface achieving a hardness of approximately 20.6 GPa, representing more than a four-fold increase compared to the untreated titanium substrate.
