Biodegradable Magnesium Alloys: A Review of Material Development and Applications.
Magnesium based alloys possess a natural ability to biodegrade due to corrosion when placed within aqueous substances, which is promising for cardiovascular and orthopedic medical device applications. These materials can serve as a temporary scaffold when placed in vivo, which is desirable for treatments when temporary supportive structures are required to assist in the wound healing process. T...
متن کاملSecurity assessment of magnesium alloys used as biodegradable implant material.
The security risk of magnesium alloys used as biodegradable implant material was evaluated in this study. Dose-response assessment was conducted by using toxicological data from authoritative public health agencies (World Health Organization) and assuming 1~3 years of uniform corrosion. Through modification calculation, the tolerable corrosion rate of biodegradable magnesium alloys in vivo was ...
متن کاملMagnesium-based biodegradable alloys: Degradation, application, and alloying elements
In recent years, the paradigm about the metal with improved corrosion resistance for application in surgery and orthopedy was broken. The new class of biodegradable metal emerges as an alternative for biomedical implants. These metals corrode gradually with an appropriate host response and release of corrosion products. And it is absolutely necessary to use essential metals metabolized by hosti...
متن کاملBiodegradable Orthopedic Magnesium-Calcium (MgCa) Alloys, Processing, and Corrosion Performance
Magnesium-Calcium (Mg-Ca) alloy has received considerable attention as an emerging biodegradable implant material in orthopedic fixation applications. The biodegradable Mg-Ca alloys avoid stress shielding and secondary surgery inherent with permanent metallic implant materials. They also provide sufficient mechanical strength in load carrying applications as opposed to biopolymers. However, the...
متن کاملCorrelation between the surface chemistry and the atmospheric corrosion of AZ31, AZ80 and AZ91D magnesium alloys
* Corresponding author. Tel: 34 1 3944348; Fax: 34 1 3944357 E-mail: [email protected] ABSTRACT X-ray photoelectron spectroscopy (XPS) was used in order to investigate the correlation between the surface chemistry and the atmospheric corrosion of AZ31, AZ80 and AZ91D magnesium alloys exposed to 98% relative humidity at 50oC. Commercially pure magnesium, used as the reference material, reveale...
