Corrosion and Mechanical Behavior of Biodegradable Metallic Biomaterials

Article Preview

Abstract:

Biodegradable alloys are currently studied as prospective biomaterials for temporary medical implants like stents and fixation devices for fractured bones. Among biodegradable metals, only magnesium, zinc and iron meet general requirements of biocompatibility and relative non-toxicity. In the present paper, Mg-, Zn- and Fe-based biodegradable alloys are compared. Advantages and disadvantages of the three kinds of alloying systems are demonstrated regarding the corrosion behavior, mechanical performance and biocompatibility. From the corrosion behavior point of view, Zn- and Fe-based alloys appear as promising alternatives to Mg-based alloys.
