Corrosion Resistance and Biological Properties of Pure Magnesium Modified by PEO in Alkaline Phosphate Solutions
نویسندگان
چکیده
Magnesium (Mg) has been explored during the last few decades in biomedical industry as a biodegradable implant. However, mechanical properties and corrosion resistance are still big concerns for clinical use. Therefore, this study proposes suitable surface modification of Mg by plasma electrolytic oxidation (PEO) to improve its biological performance. samples were processed galvanostatic mode using an solution phosphate compound supplemented with either potassium pyrophosphate or sodium-potassium tartrate. The obtained coatings physiochemically characterized SEM, XRD, EDS, micro-Raman spectroscopy. was studied hydrogen evolution setup electrochemical tests. Finally, performance material evaluated indirect test osteoblasts. Obtained showed porous morphology thicknesses ranging from 2 3 µm, which closely dependent on PEO solution. tests improved degradation rate compared raw material. Additionally, unreported active–passive behavior evidence protective layer products underneath anodic coating. Indirect vitro cytotoxicity assays indicated that biocompatibility In conclusion, it found produced not only lead protection but also ensure cell survival, indicating could be potential used bone implants.

Removal of Cerium from Aqueous Solutions by Amino Phosphate Modified Nano TiO2: Kinetic, and Equilibrium Studies
Adsorption of Ce(III) from aqueous solution by amino phosphate modified nano TiO2 was investigated. Effects of pH of solution, adsorbent dose, contact time, initial metal concentration and temperature were examined. Experimental data were fitted well by the pseudo second order model. Adsorption was well described by Freundlich isotherm model with a maximum adsorption capacity of 25 mg g-1. Acco...

15 صفحه اولControlling the Mechanical Properties and Corrosion Resistance of Mild Steel by Intercritical Annealing and Subcritical Tempering
The effects of intercritical annealing and subcritical tempering on the mechanical properties and corrosion resistance of mild steel were studied. It was revealed that intercritical annealing followed by quenching resulted in the development of a ferritic-martensitic dual phase (DP) microstructure with high tensile strength, disappearance of the yield-point phenomenon, superior work-hardening b...

Cerium conversion coatings are a potential alternative to chromium conversion coatings for improving the corrosion resistance of magnesium alloys. This study detailed the microstructure and corrosion resistance of cerium conversion coatings on AZ31 magnesium plates treated in 0.05 kmolm 3 cerium nitrate solution, with and without 0.25 kmolm 3 hydrogen peroxide. The results indicate that the cor...
