Electrochemical corrosion behavior of biodegradable Mg–Y–RE and Mg–Zn–Zr alloys in Ringer’s solution and simulated body fluid

Evaluation of corrosion resistance and cytocompatibility of graded metal carbon film on Ti and NiTi prepared by hybrid cathodic arc/glow discharge plasma-assisted chemical vapor deposition

“…Additional details about the electrochemical experiments can be found from our earlier articles [33,43,45,61]. The NaCl solution having inorganic Na + and Cl À ions concentrations (154 mM Na + and 154 mM Cl À ) similar to those in human body fluids was used as the electrolyte in this study [62].…”

“…The normal body fluid pH of about 7.4 diminishes to about 5.2 during the initial period (about 2 weeks) after hard tissue implantation [7] and Ti and Ti alloys corrode differently depending on the environment and conditions. The in vivo corrosion behavior of Ti and released Ti ions accumulated in the tissues near the implant surface have been studied [32] and electrochemical techniques such as electrochemical impedance spectroscopy and potentiodynamic polarization are useful in monitoring the corrosion process and elucidate the mechanism [33]. Formation of a surface oxide layer such as TiO 2 on Ti by thermal oxidation, chemical oxidation, electrochemical oxidation, and arc process can improve the corrosion resistance.…”

Hydroxyapatite coating on AZ91 magnesium alloy via sol-gel method

“…Günümüz biyomalzeme uygulamalarının gözde konusu kemiğin kimyasal yapısı ve mekanik özellikleriyle doğrudan benzeyen Magnezyum alaşımlarıdır [1]- [5]. Özellikle yoğunluğu ve elastik modülü, 1.74-2 g/cm 3 ve 41-45 GPa olup kemiğinkine çok yakındır (1.8-2.1 g/cm 3 , 3-20 GPa) [6]. Ancak bu alaşımın biyobozunur olması vücuttaki kullanımını güçleştirmektedir.…”

Influence of Alloying Treatment and Rapid Solidification on the Degradation Behavior and Mechanical Properties of Mg

“…Magnesium (Mg), as a promising biomaterial, has attracted much attention due to its natural biodegradability and favorable cytocompatibility [1,2]. Moreover, it plays essential roles in human metabolism, cellular structure and function, and bone growth [3][4][5].…”
