摘要

Biodegradable Mg-Cu alloys have attracted many researchers attention due to their characteristics of osteogenesis, angiogenesis, and long-lasting antibacterial effects. In this paper, the effect of copper content on the corrosion behaviors and antibacterial properties of binary Mg-Cu alloys was studied. Microstructure characterization, immersion test, electrochemical test and antibacterial test were carried out. The results show that with the increase of Cu content, the corrosion rate of Mg-Cu alloys was increased greatly due to the galvanic corrosion between Mg matrix and Mg2Cu intermetallic phase. The corrosion rate of Mg-0.3Cu alloy was almost 10 times as fast as Mg-0.1Cu alloy in 0.9 wt-% NaCl solution. Antibacterial test showed that Mg-Cu alloys could efficiently reduce the viability of Candida albicans with the addition of Cu above 0.1 wt%. Mg-0.1Cu has good potential to be used as antibacterial implants due to its good corrosion resistance and antibacterial property.

Effects of Indium on corrosion behavior of Mg-Al-Cu alloy

X. W. Wang, W. Wang, W. Chen, D. M. Chen

Summary: The study found that the weight loss rates of alloys in NaCl solution increase with the addition of In and at higher water temperatures, with the alloys exhibiting the highest weight loss rates at 70 degrees C and 90 degrees C. Electrochemical measurements were conducted to study the corrosion behavior of Mg-Al-Cu-In alloys, and the reasons for the different corrosion behaviors were discussed.

The effect of solute segregated stacking faults on the corrosion behavior of Mg-Gd-Cu alloys

Kai Ma, Jingfeng Wang, Wenxuan Zheng, Yinhong Peng, Chaoneng Dai, Yuanlang Pan, Ye Wang, Danqian Wang, Jinxing Wang, Yanlong Ma

Summary: Research findings show that Mg-Gd-Cu alloys containing profuse solute segregated stacking faults (SFs) exhibit significantly different corrosion behavior compared to ordinary alloys. These alloys display higher initial corrosion rates due to the increased volume fraction of the cathodic phase associated with the SFs. However, they also have a rapid formation ability and a uniform and complete distribution of corrosion films, resulting in a lower average degradation rate.

Influence of Cu/Mg ratio on microstructure and mechanical properties of Al-Zn-Mg-Cu alloys

Shilong Wei, Richu Wang, Hui Zhang, Chunting Xu, Ying Wu, Yan Feng

Summary: The Cu/Mg ratio affects the precipitation rate and mechanical properties of Al-Zn-Mg-Cu alloys, with alloys with lower Cu/Mg ratio exhibiting higher strength and slower coarsening rate. As the Cu/Mg ratio increases, the fracture mode changes from brittle to ductile, and alloys with higher Cu/Mg ratio have coarser and wider grain boundary precipitates.

Enhanced Degradability of Mg-2Gd Alloy by Alloying Cu

Shiyu Zhong, Dingfei Zhang, Junyao Xu, Jie Zhou, Yang Zhao, Jingkai Feng, Yongqin Wang, Bin Jiang, Fusheng Pan

Summary: The addition of Cu into Mg-2Gd alloy resulted in improved mechanical properties but also significantly increased the corrosion rate. This was attributed to the formation of second phases, refinement of grain size, and weakening of rare earth texture due to Cu addition.

Effect of Zr content on corrosion behavior and chemically-milled surface roughness of Al-Cu-Mg alloy

Pan Deng, Wenfeng Mo, Zuoqiong Ouyang, Junwei Chen, Binghui Luo, Zhenhai Bai

Summary: In this study, the effects of adding Zr to Al-3.8Cu-1.2Mg alloys on microstructural evolution, intergranular corrosion, electrochemical corrosion, and chemically-milled surface roughness were investigated. The experimental results showed that the addition of 0.2 wt% Zr could refine the grain size, improve solidification segregation, increase the spacing of grain boundary precipitation phases, enhance corrosion resistance, and optimize the chemically-milled surface roughness. This finding provides a valuable strategy for achieving high corrosion resistance and superior chemically-milled surface roughness properties in aircraft skin materials for the aerospace field.

Effect of the Cu/Mg Ratio on Mechanical Properties and Corrosion Resistance of Wrought Al-Cu-Mg-Ag Alloy

Talal Talib Alshammari, Muhammad Farzik Ijaz, Hamad F. Alharbi, Mahmoud S. Soliman

Summary: The influence of magnesium (Mg) on the mechanical properties and corrosion behavior of Al-4Cu-xMg-0.6Ag alloys was investigated. The microstructure formed after the aging process was identified using Optical Microscope, SEM, XRD analysis, and Thermo-Calc simulation. Hardness and tensile strength testing, as well as corrosion testing, were conducted. It was found that Mg significantly impacts the hardness of the alloys, with a high Mg content increasing the hardness but reducing the tensile strength and ductility. The corrosion activity was reduced in the high-Mg-content alloy due to its larger particle size and reduced galvanic cell effect.

In vitro degradation and multi-antibacterial mechanisms of β-cyclodextrin@curcumin embodied Mg(OH)2/MAO coating on AZ31 magnesium alloy

Kui Xue, Pei-Hong Tan, Ze-Hui Zhao, Lan-Yue Cui, M. Bobby Kannan, Shuo-Qi Li, Cheng-Bao Liu, Yu-Hong Zou, Fen Zhang, Zhuo-Yuan Chen, Rong-Chang Zeng

Summary: In this research work, a Mg(OH)2 coating was formed on the surface of micro arc oxidation (MAO) coated AZ31 alloy through a low temperature hydrothermal method, incorporating sodium alginate (SA) and beta-cyclodextrin (beta-CD)@curcumin (Cur). The coating exhibited excellent corrosion protection, multi-antibacterial ability and almost no toxicity to the cells. The photothermal performance of the coating was achieved through the light absorption of encapsulated Cur by beta-CD, while SA enhanced the binding force between the drug and the substrate.

Microstructure and corrosion behaviors of as-rolled Mg-Zn-Er alloy sheets

Ke Liu, Feng Lou, Jun-jian Fu, Zi-jian Yu, Shu-bo Li, Zhao-hui Wang, Xian Du, Wen-bo Du

Summary: The corrosion behaviors and mechanism of Mg-xZn-0.5Er (x = 0.5, 2.0, 3.0 and 4.0, in wt.%) alloys were investigated. The potential difference between the second phase and matrix was determined by the type and size of the second phases. The dominated nano-scale W-phase on the matrix induced sharp local pitting corrosion, while an increase in the volume fraction of the coarse W-phase or I-phase resulted in preferential corrosion around them, leading to obvious uniform corrosion and an accelerated corrosion rate.
