TL;DR: Magnesium alloys are very biocompatiable and show promise for use in orthopaedic implant as mentioned in this paper and significant progress of research on bioabsorbable magnesium stents and orthopedic bones has been achieved in recent years.
Abstract: Magnesium alloys are very biocompatiable and show promise for use in orthopaedic implant. Significant progress of research on bioabsorbable magnesium stents and orthopaedic bones has been achieved in recent years. The issues on degradation, hydrogen evolution, and corrosion fatigue and erosion corrosion of magnesium alloys and various influencing factors in simulated body fluid (SBF) are discussed. The research progress on magnesium and its alloys as biomaterials and miscellaneous approaches to enhancement in corrosion resistance is reviewed. Finally the challenges and strategy for their application as orthopaedic biomaterials are also proposed.

TL;DR: Investigation in vitro of a MMC made of magnesium alloy AZ91D as a matrix and hydroxyapatite (HA) particles as reinforcements have been investigated in vitro for mechanical, corrosive and cytocompatible properties revealed that biodegradable MMC-HA are cytcompatible biomaterials with adjustable mechanical and corrosive properties.

TL;DR: The influence of composition and heat treatments on the microstructure, mechanical properties and corrosion behaviour of cast Mg-Gd alloys is discussed and recommended for the design of future degradable magnesium based implant materials.

TL;DR: In this paper, the authors summarized the existing fundamental studies and technical developments of anodizing of magnesium alloys, and concluded that new anodising processes based on electrolytic plasma anodization that convert the surface of a magnesium alloy into a hard ceramic coating in an electrolytic bath using high energy electric discharges can offer improved wear and corrosion resistance.
Abstract: This paper reviews various aspects of anodizing of magnesium alloys, such as the basics, processes, properties and applications. It systematically summarises the existing fundamental studies and technical developments of anodizing of magnesium alloys, and concludes that new anodizing processes based on electrolytic plasma anodizing that convert the surface of a magnesium alloy into a hard ceramic coating in an electrolytic bath using high energy electric discharges can offer improved wear and corrosion resistance. These new anodized coatings are often claimed to perform better than the traditional ones obtained through older anodizing processes, such as DOW17 or HAE. The new anodizing techniques are chromate free and hence environment friendly. It is expected that more cost-effective, environment-friendly and non-toxic anodizing techniques will be developed and applied to magnesium alloy components in the future.

TL;DR: In this paper, a mechanism of pitting corrosion caused by AIMn particles was proposed and the corrosion properties of AZ91D weld material were investigated, and the influence of metallurgical factors, such as alloying elements, microstructure and secondary phases, processing factors such as heat treatment and weld, and environmental factors including temperature, relative humidity, solution pH values and concentration on corrosion were discussed.

TL;DR: Magnesium and its alloys have been investigated recently by many authors as a suitable biodegradable biomaterial as mentioned in this paper, and the latest achievements and comment on the selection and use, test methods and the approaches to develop and produce magnesium alloys that are intended to perform clinically with an appropriate host response.
Abstract: Biodegradable metals are breaking the current paradigm in biomaterial science to develop only corrosion resistant metals. In particular, metals which consist of trace elements existing in the human body are promising candidates for temporary implant materials. These implants would be temporarily needed to provide mechanical support during the healing process of the injured or pathological tissue. Magnesium and its alloys have been investigated recently by many authors as a suitable biodegradable biomaterial. In this investigative review we would like to summarize the latest achievements and comment on the selection and use, test methods and the approaches to develop and produce magnesium alloys that are intended to perform clinically with an appropriate host response.

TL;DR: The results of tensile tests and in vitro corrosion tests indicated that Mg-1Ca alloy had the acceptable biocompatibility as a new kind of biodegradable implant material and a solid alloy/liquid solution interface model was proposed to interpret the biocorrosion process and the associated hydroxyapatite mineralization.
