Gaoya dianqi, 2020 近期发现南网地区部分输电杆塔塔脚出现严重的腐蚀,经现场调研发现多处出现腐蚀的塔脚都被农田的土壤覆盖,土壤为塔脚腐蚀提供了良好的介质。为了研究腐蚀的杆塔塔脚腐蚀机理,获得实时测量的腐蚀数据十分重要。文中首先开展了塔脚腐蚀监测方法的研究,利用腐蚀电化学原理,提出了一种基于"条形槽"结构的腐蚀监测传感器,并开发了一套数据监测系统。接着对腐蚀监测系统的性能进行测试工作,得到了塔脚腐蚀测量系统在滴水条件、盐雾环境和干湿循环条件下的特性。最后将该系统安装到出现了塔脚腐蚀的现场,测量当地的腐蚀电流。结果表明 ...

Gaoya dianqi, 2022 采用腐蚀产物形貌结构分析方法（SEM、EDS、XRD）以及电化学测试方法，研究了在模拟高温高湿环境下腐蚀时间以及外加不同强度直流电场对电力杆塔用碳钢腐蚀行为、腐蚀产物以及形貌结构的影响。结果表明，随着腐蚀时间的延长，碳钢表面的腐蚀产物不断发生变化，腐蚀最初期的腐蚀产物以棉球状α-FeOOH为主，逐渐发展变化为片状的γ-FeOOH和尖晶长条状的Fe3O4，导致表面的腐蚀产物致密性相比腐蚀初期大大减小，对内部基底的保护作用减弱。而电场的存在则会在腐蚀时间作用的基础上进一步抑制α-FeOOH的生成、加速γ ...

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

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 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

Hybrid Flexible–Soft Neural Interface as a Practical Solution for Long‐Term Implants
Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT Implantable neural interfaces face persistent challenges in long‐term functionality due to chronic immune responses, mechanical mismatch with tissue, and material corrosion in vivo. The commonly used flexible materials, such as polyimide and parylene‐C (poly[monochloro‐p‐xylylene]), have advantages in low water vapor permeability and high ...

Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT Ti‐15Mo‐2.5Ag alloy exhibited a low modulus and strong antibacterial ability but poor bioactivity. To resolve this problem, sandblasting and anodization were used to create a hydrophilic and nano‐Ag2O‐containing TiO2 coating. Subsequently, the microstructure and physicochemical properties were investigated by scanning electron microscopy, X ...

Dianci bileiqi, 2016 为找出某500 k V变电站地网腐蚀断裂原因,通过X射线物相分析了地网腐蚀产物和降阻剂成分,对变电站地网周围土壤和降阻剂进行了理化分析和腐蚀电化学试验。分析试验结果得出,地网腐蚀的主要原因是降阻剂腐蚀和硫酸盐还原菌腐蚀。针对腐蚀原因提出了改造措施:更换被腐蚀地网同时清除地网周围降阻剂,在较易发生腐蚀的集中接地装置周围及新换地网与旧地网连接处施加环保高效膨润土防腐剂。
