Dianci bileiqi, 2020 通过改变氧化锑的含量,分析不同含量对氧化锌电阻片电位梯度、泄漏电流等性能的影响。氧化锑在烧结过程中与氧化锌可以形成尖晶石相,可以抑制氧化锌晶粒尺寸的大小,进而调整电阻片电位梯度。在传统五元配方体系中,通过改变氧化锑的增加,电阻片收缩率逐渐增大,致密度逐渐增加;掺杂适量的氧化锑可以提高电位梯度,降低泄漏电流;掺杂过量的氧化锑会降低电位梯度。

Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT NiTi shape memory alloys (SMAs) show excellent performance in vibration damping and corrosion resistance. However, due to low hardness and lack of self‐lubrication, they suffer severe friction and wear during service. Although various strategies including doping and heterostructure design have been proposed, the effects are unsatisfactory.
