GaAlAs—GaAs、InGaAs—InP光电器件的表面特性与有机钝化
Guangtongxin yanjiu, 1984 本文讨论了GaAlAs-GaAs、InGaAs-InP光电器件中反向漏电大,性能不稳定的各种因素。为使器件反向电流减少和稳定可靠,必须采用表面钝化措施。比较了无机钝化和有机钝化的优缺点,指出用聚酰亚胺作为多种半导体器件表面钝化膜的优点和实用价值。

, 2012 针对旋成体高超声速飞行器，采用一种新的钝化外形。基于CFD 数值模拟分析，完成了新钝化外形和圆锥钝化在气动力方面性能的比较。对三种不同钝化半径/旋成体最大半径（r/R）比1/40、1/20、1/10 比较分析，结果表明，在相同的钝化半径下，钝锥部分阻力系数增加，但对整个旋成体导弹而言 ...

Pitting Behaviors of Passivated and Trans-Passivated 304 Stainless Steel
, 2020 为了进一步了解不锈钢钝化膜与过钝化膜的性质,本文对比研究了在不同电位下极化处理后304不锈钢样品的点蚀及表面膜性质,发现空白对照组样品的点蚀电位和1.1 V过钝化处理后样品的点蚀电位相近,而0.5 V钝化处理后样品的点蚀电位较高. 扫描Kelvin探针（SKP）实验结果也验证了这一现象. 扫描电子显微镜（SEM）结果显示,空白对照组样品表面只呈现一般样品抛光后形貌;0.5 V钝化处理后的样品表面被颗粒状钝化膜所覆盖,该膜层决定了样品具有较好的耐蚀性;而1.1 V过钝化处理后的样品表面出现裂缝 ...

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Aqueous Zn‐ion batteries (AZIBs) are expected to become one of the most promising candidates for large‐scale energy storage, but are impeded by uncontrollable dendrite growth and parasitic reactions. In this study, we propose a simple mechanical shot‐peening (SP) approach for restructuring commercial Zn foils into highly exposed (002)‐textured

, 2011 用指数率前缘代替传统圆弧形前缘给乘波飞行器提供了一种可能的钝化方式。本文利用数值方法对三维高超声速乘波体指数率前缘进行了研究，选取了一个乘波前体作为计算的物理模型，分别采用指数率前缘和传统的圆弧形前缘进行钝化，对两种不同钝化方式计算所得的气动力、热特性进行了对比分析。对于所考虑的计算工况，乘波体的指数率前缘所受到的阻力更小，同时它有一定的钝度以减轻热防护压力，并且可以通过选取适当的指数来调整前缘钝度，以满足热防护需求 ...

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Zinc‐based biodegradable metals are promising implant materials, and additive manufacturing offers a powerful route for their patient‐specific fabrication. However, process‐induced surface defects can accelerate degradation and compromise biocompatibility, rendering post‐processing essential.

TA10 Titanium Alloy in HCl Solution: W‐Influenced Corrosion and Passivation Film Evolution
Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT This work investigated the evolution of passive films of Ti–0.3Mo–0.8Ni (TMN) in 5 mol L−1 HCl and studied the influence of W on the anti‐corrosion properties of TMN. The intermittent electrochemical impedance spectroscopy test results showed that when TMN entered 5 mol L−1 HCl solution, the stability of the passive film first became stronger ...

Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT Rationally selection of precursor additives during perovskite crystallization is essential for obtaining high‐quality films and achieving high‐performance perovskite solar cells (PSCs). However, the discovery and optimization of effective additives still rely heavily on time‐consuming and costly trial‐and‐error experiments.

Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT Aqueous zinc batteries hold great promise for large‐scale energy storage, yet their practical application is hindered by dendrite growth and interfacial side reactions on the zinc anode. Inspired by the industrially mature chromate passivation technology, this work reports an in situ construction of a chromium‐rich passivation layer (Zn@Cr) on
