Electrochemical Analysis of Some Biodegradable Mg-Ca-Mn Alloys

Abstract

The potential benefits of magnesium (Mg) over the other non-resorbable biomaterials, especially for orthopedic applications, are obvious. When fully realized, functional bioresorbable implants based on Mg alloys offer the mechanical advantages of a metal combined with the degradable and biological advantages of polymers and biomaterials. <1>In this article we obtained aMg-based prelate alloyed with Ca and Mn. It is known that Mn helps to refine the alloy’s microstructure, which adds to the elasticity of the material. Surface morphology was performed using the optical microscope and the electron microscope while the mechanical tests were performed using the tribometer. Also, the electrochemical tests were executed in the ringer solution. It has been mentioned that the electrochemical resistance is quite low. This study was conducted to determine the corrosion resistance of Mg-Ca-Mn alloys. It has been demonstrated that the addition of Mn refines the microstructure, increases the modulus of elasticity but does not have a qualitative resistance to corrosion.Also, the hardness of the material is quite low in comparison to other pre-alloys of Mg.
