Tailoring of Biodegradable Magnesium Alloy Surface with Schiff Base Coating via Electrostatic Spraying for Better Corrosion Resistance
نویسندگان
چکیده
In this study, three new Schiff bases were synthesized from paeonol and amino acids to prepare a compound base coating on the Mg-Zn-Y-Nd alloy (ZE21B alloy) surface by electrostatic spraying, these single coatings prepared ZE21B as control. The results of SEM XPS confirmed successful preparation coating. Immersion tests electrochemical showed that both significantly improved corrosion resistance alloy, could play synergistic inhibition effect, thus showing best resistance.

Corrosion resistance and cytocompatibility of biodegradable surgical magnesium alloy coated with hydrogenated amorphous silicon.
The fast degradation rates in the physiological environment constitute the main limitation for the applications of surgical magnesium alloys as biodegradable hard-tissue implants. In this work, a stable and dense hydrogenated amorphous silicon coating (a-Si:H) with desirable bioactivity is deposited on AZ91 magnesium alloy using magnetron sputtering deposition. Raman spectroscopy and Fourier tr...
متن کاملCorrosion Resistance Enhancement of AZ91 Magnesium Alloy Using Ni-P Interlayer and Electrophoretic Deposited 3YSZ Coating
The zirconia stabilized by 3mol % Y2O3 (3YSZ) was applied onto the surface of the magnesium alloy AZ91D using electrophoretic deposition (EPD) from a non- aqueous solution. A Ni-P interlayer between the substrate and YSZ coating was also prepared by electroless plating. Finally, coatings were heat treated in control atmosphere at 400 °C. The preparation, microstructure and corrosion resistance ...
متن کاملMitigation of Corrosion on Magnesium Alloy by Predesigned Surface Corrosion
Rapid corrosion of magnesium alloys is undesirable in structural and biomedical applications and a general way to control corrosion is to form a surface barrier layer isolating the bulk materials from the external environment. Herein, based on the insights gained from the anticorrosion behavior of corrosion products, a special way to mitigate aqueous corrosion is described. The concept is based...

The protective performance of zeolite coating on AZ91D magnesium alloy was evaluated using potentiodynamic polarisation and electrochemical impedance spectroscopy (EIS) in 0.1 M sodium chloride solution (NaCl). Electrical equivalent circuit (EEC) was developed based upon hypothetical corrosion mechanisms and simulated to correspond to the experimental data. The morphology and the chemical natur...
متن کاملFabrication of a Delaying Biodegradable Magnesium Alloy-Based Esophageal Stent via Coating Elastic Polymer
Esophageal stent implantation can relieve esophageal stenosis and obstructions in benign esophageal strictures, and magnesium alloy stents are a good candidate because of biodegradation and biological safety. However, biodegradable esophageal stents show a poor corrosion resistance and a quick loss of mechanical support in vivo. In this study, we chose the elastic and biodegradable mixed polyme...
