Corrosion and passive film characteristics of 3D‐printed NiTi shape memory alloys in artificial saliva

open access: yesRare Metals, Volume 42, Issue 9, Page 3114-3129, September 2023., 2023
Graphic Abstract Abstract Electrochemical tests and surface analysis were applied to study the corrosion behavior and passive film characteristics of three‐dimensional‐printed NiTi shape memory alloys fabricated by laser‐powder bed fusion (L‐PBF) in artificial saliva at 37 °C. The passivity of L‐PBF NiTi shows to be influenced by the process parameters

随机变幅载荷下海水腐蚀疲劳裂纹扩展速率的断裂力学参量选择 [PDF]

open access: yes, 1994
# 本文就随机变幅载荷下疲劳裂纹扩展速率的断裂力学参量的选择进行了分析;并与压机变幅载荷下焊接接头海水腐蚀疲劳裂纹扩展试验数据进行了比较;由此认为采用△K_(rms) ;作为断裂学控制参量是可取的;并且认为用常幅循环加载下的焊接接头海水腐蚀疲劳裂纹扩展速率曲线代替以△K_(rms)为参量的随机变幅加载下的裂纹扩展速率曲线;以此来估算其海水腐蚀疲劳裂纹扩展寿命;在工程应用上不仅方便可行 ...

Grain Boundary Density Governs the Discharge Behavior of Mg Anodes in Biodegradable Batteries

open access: yesRare Metals, Volume 45, Issue 11, November 2026.
ABSTRACT Biodegradable magnesium (Mg) alloys have entered clinical use, yet their development as self‐powered absorbable batteries is hindered by poor anode performance, including high self‐corrosion, passivation, and nonuniform dissolution. The role of grain boundary density in governing discharge behavior remains unclear.

Interface‐Stabilized Glass‐Ceramic/Silver Composite Coatings Enable Predictable Multiband Infrared Stealth Under High‐Temperature Marine Environment

open access: yesRare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT Infrared (IR) stealth is crucial for improving the survivability of equipment. The growing demand for service in marine environments poses new challenges to the composition and structural design of existing IR stealth coatings. This study first investigates the effects of NaCl/water vapor corrosion on the IR stealth performance of GH3536 and a

Influence of Alkaline Earth Barium on the Microstructure, Corrosion Behavior, and Cytocompatibility of Biodegradable Zinc

open access: yesRare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Biodegradable Zn‐based alloys are promising candidates for temporary implants, yet excessive Zn2+ release during degradation may induce cytotoxicity and adverse tissue responses. In this study, Zn‐xBa alloys (x = 0.1 wt%, 0.5 wt%, 1.0 wt% and 3.0 wt%) were developed to achieve controlled corrosion behaviors with improved biocompatibility.
