The rapid corrosion rate of biodegradable Magnesium (Mg) implants in physiological environments compromises their mechanical integrity and inhibit bone healing. To improve the magnesium alloy AZ31's resistance bioactivity, this study applies bi-layered coatings hydroxyapatite (HA) beta-tricalcium phosphate (β-TCP). high-velocity oxygen fuel (HVOF) spraying technique has developed HA/TCP with superior adhesion, low porosity, high density. These form a protective barrier against simulated body fluid (SBF), significantly enhancing resistance. on AZ31 substrates, thickness 42.6 µm crystallinity (>70%), reduced current density (Icorr) from 174.03 µA/cm2 to 30.25 µA/cm2, decreasing 3.98 mm/year 0.69 mm/year. According EIS testing, coated sample's charge transfer (Rct) increased 147.47 Ω·cm2 1539.38 Ω·cm2. SEM EDS analysis revealed that after ten days immersion, there was reduction Ca/P ratio 1.51 1.27, indicating dissolution coating. examination confirmed formation an apatite layer, which validated surface bioactivity. results suggest substantially Mg implants' activity biodegradation capabilities, making them promising candidates for advanced biomedical applications.

Medical implants are designed to replace missing parts or improve body functions and must be capable of providing structural support therapeutic intervention for a medical condition. Advances in materials science have enabled the development devices made from metals, polymers, bioceramics, composites, each with its specific advantages limitations. This review analyzes incorporation biopolymers, proteins, other biomacromolecules into implants, focusing on their role biological integration functions. It synthesizes advancements surface modification, discusses as carriers controlled drug release, explores application nanoceramics composites osseointegration tissue regeneration. Biomacromolecule systems interacting device components agents - such growth factors (GFs), antibiotics, allowing control over substance release. Incorporating these enables localized treatments regeneration, osseointegration, post-surgery infection control, disease pre-existing conditions. The highlights materials' customization opportunities, by covering mechanical perspectives. Developing hybrid delivery align recent efforts interdisciplinary personalized medicine implant innovations. For instance, trend was observed integrating inorganic (especially nanoceramics, e.g., hydroxyapatite) organic phases better interaction tissues faster recovery. article supports understanding how can create more personalized, functional, durable, biocompatible devices.

This study explores the efficacy of amine derivatives (aniline and n-butylamine) in preventing corrosion mild steel a 1.0 M HCl solution. Employing combination potentiodynamic polarization techniques electrochemical impedance spectroscopy (EIS), assesses process. Furthermore, scanning electron microscopy (SEM) was used to analyze changes surface morphology presence derivatives, while UV-visible (UV-Vis) Fourier-transform infrared (FTIR) provided additional insights into protective mechanisms at play. The results indicated that achieved inhibition efficiencies 85.96% 67.39%, respectively. inclusion nitrogen atom structure enhanced performance these inhibitors. FTIR-ATR spectra revealed N-H stretching, which is indicative groups reacting with acid metal form films, thereby inhibiting corrosion. UV-Vis has confirmed formation complex between Fe2+/Fe3+ ions inhibitors, corroborating observed. SEM analysis inhibitors effectively condition comparison untreated samples demonstrating their ability make significant impact extend lifespan durability structures corrosive environments.
