“…A high-frequency semicircle capacitive loop and a mid-to-low-frequency depressed semicircle loop can be observed (Figure a). These two impedance features are commonly attributed to the charge transfer process and the partially protective permeable surface layer, respectively. , The size of the capacitive loop radius, which is directly proportional to total impedance, may be related to the sample’s corrosion rate; i.e., a decreasing radius indicates faster corrosion. Fe35Mn/30Ake and Fe35Mn/50Ake showed smaller loop radii than those of pure Fe35Mn and Fe35Mn/10Ake, indicating their higher corrosion rates, which was consistent with the data obtained from potentiodynamic polarization tests (Table ).…”

As a representative of the biodegradable iron (Fe)− manganese (Mn) alloys, Fe35Mn has been investigated as a promising biodegradable metal biomaterial for orthopedic applications. However, its slow degradation rate, though better than pure Fe, and poor bioactivity are concerns that retard its clinical applications. Akermanite (Ca 2 MgSi 2 O 7 , Ake) is a silicatebased bioceramic, showing desirable degradability and bioactivity for bone repair. In the present work, Fe35Mn/Ake composites were prepared via a powder metallurgy route. The effect of different contents of Ake (0, 10, 30, 50 vol %) on the microstructure, mechanical properties, degradation, and biocompatibility of the composites was investigated. The ceramic phases were found to be evenly distributed in the metal matrix. The Ake reacted with Fe35Mn and generated CaFeSiO 4 during sintering. The addition of Ake increased the relative density of pure Fe35Mn from ∼90 to ∼94−97%. The compressive yield strength (CYS) and elastic modulus (E c ) increased with increasing Ake, with Fe35Mn/50Ake exhibiting the highest CYS of ∼403 MPa and E c of ∼18 GPa. However, the ductility decreased at higher Ake concentrations (30 and 50%). Microhardness also showed an increasing trend with the addition of Ake. Electrochemical measurements indicated that higher concentrations of Ake (30 and 50%) could potentially increase the corrosion rate of Fe35Mn from ∼0.25 to ∼0.39 mm/year. However, all of the compositions tested did not show measurable weight loss after immersion in simulated body fluid (SBF) for 4 weeks, attributed to the use of prealloyed raw material, high sintered density of the fabricated composites, and the formation of a dense Ca-, P-, and O-rich layer on the surface. Human osteoblasts on Fe35Mn/Ake composites showed increasing viability with increasing Ake content, indicating improved in vitro biocompatibility. These preliminary results suggest that Fe35Mn/Ake can be a potential material for biodegradable bone implant applications, particularly Fe35Mn/30Ake, if the slow corrosion of the composite can be addressed.

“…The research required first is the evaluation of the corrosion rate and corrosion behavior of biodegradable metals in the subcutaneous environment which represents the environment of the pelvic floor. A first step has been carried out by Mardina et al 166 The next step is to evaluate the influence of corrosion on the mechanical properties of biodegradable metals and mesh. Studies are required involving a suitable combination of alloys and heat treatments to identify alloys with suitable corrosion and mechanical properties.…”

“…Mardina et al 166 found that the corrosion rate of the biodegradable metals in the subcutaneous environment was 0.24 mm per year for the Mg alloy WE43, 0.008 mm per year for pure zinc, and 0.005 mm per year for pure iron. 166 While tissue maturation is expected to be complete within two years, the mesh is expected to be intact for a longer period, estimated to be two and half years. Therefore, the ideal degradation rate is 0.03 mm per year for a The first tantalum mesh used as an implant for hernia surgery was too stiff, so that the mesh could be felt underneath the skin and caused discomfort soon after implantation, as reported by Flynn et al 167 However, these complaints were raised by only 3 of 45 patients.…”

“…Magnesium alloys are 1/3 lighter than aluminium and 7/10 lighter than stainless steel, in addition to being relatively affordable and readily available. The application of magnesium alloys is diverse, ranging from aerospace, automotive, biomedical, manufacturing and green energy technologies (Acheson et al , 2021; Fan et al , 2020; Liu and Schlesinger, 2009; Mardina et al , 2022). Magnesium alloys provide material scientists with practical, high-performing and readily available solutions to the persistent challenge of optimizing weight, strength, power and cost.…”

Purpose In line with current research efforts to develop eco-friendly strategies for corrosion mitigation, the purpose of this study is to appraise the anti-corrosion potential of selected amino acids on magnesium corrosion in sodium chloride solutions. Design/methodology/approach The corrosion inhibition of magnesium in aqueous solutions in the presence of benign, eco-friendly and readily available amino acids (alanine, arginine, histidine, lysine, proline) were evaluated using electrochemical methods. Findings Amino acids suppressed magnesium corrosion rate in aqueous sodium chloride solutions. The order of inhibition efficiency (%IE) was as follows: alanine < arginine < histidine < lysine < proline. The open circuit potential shift with respect to the blank was less than 0.085 VSCE, indicating that the amino acids are mixed-type corrosion inhibitors. In addition, the %IE of the amino acids was inversely proportional to the molecular weight. The results obtained indicate that the amino acids can serve as sustainable eco-friendly corrosion inhibitors for magnesium with the best inhibition efficiency attributed to proline with an efficiency of 85.1%. Originality/value New information on the application of amino acids as green sustainable corrosion inhibitors is provided herein.
