“…Hydrogen evolution was used to measure the corrosion resistance of the different specimens. For this purpose, a sample was placed in an inverted burette filled with 0.1 M NaCl 27,28 as is shown in Figure 1. The displacement of the liquid by production of hydrogen gas was read daily for one month.…”

The optimal mechanical properties render magnesium widely used in industrial and biomedical applications. However, magnesium is highly reactive and unstable in aqueous solutions, which can be modulated to increase stability of reactive metals that include the use of alloys or by altering the surface with coatings. Plasma electrolytic oxidation is an efficient and tuneable method to apply a surface coating. By varying the plasma electrolytic oxidation parameters voltage, current density, time and (additives in the) electrolytic solution, the morphology, composition and surface energy of surface coatings are set. In the present study, we evaluated the influence on surface coatings of two solute additives, i.e. hexamethylenetetramine and mannitol, to base solutes silicate and potassium hydroxide. Results from in vitro studies in NaCl demonstrated an improvement in the corrosion resistance. In addition, coatings were obtained by a two-step anodization procedure, firstly anodizing in an electrolyte solution containing sodium fluoride and secondly in an electrolyte solution with hexamethylenetetramine and mannitol, respectively. Results showed that the first layer acts as a protective layer which improves the corrosion resistance in comparison with the samples with a single anodizing step. In conclusion, these coatings are promising candidates to be used in biomedical applications in particular because the components are non-toxic for the body and the rate of degradation of the surface coating is lower than that of pure magnesium.

“…A fine microstructure can often be achieved by common deformation, such as single extrusion (SE) and rolling (Deng, Huang, Zhao, & Wang, 2014;Zakiyuddin, Yun, & Lee, 2014;Zhang, Yuan, & Wang, 2013d). Zhang et al (2013d) compared the corrosion properties of the as-extruded with the as-cast Mg-Nd-Zn-Zr alloy and found that the as-extruded alloy has better corrosion resistance than the as-cast one, the difference is mainly attributed to a refined and more homogenous microstructure.…”

“…Izumi, Yamasaki, and Kawamura (2009) proposed that increasing the cooling rate can reduce filiform corrosion of the Mg-Zn-Y alloy due to grain refinement and formation of a supersaturated single α-Mg solid solution. In addition, rapid solidification can improve microstructural and electrochemical homogeneities of Mg-Zn-Y alloys as well as (Deng et al, 2014;Gao et al, 2011;Peng, Li, Ma, Liu, & Zhang, 2012;Wang, Estrin, & Zúberová, 2008;Zakiyuddin et al, 2014;Zhang et al, 2012b;Zhang, Yuan, & Wang, 2012e;Zhang et al, 2013d).…”

In recent years, magnesium (Mg) alloys have attracted great attention due to superior biocompatibility, biodegradability, and other characteristics important for use in biodegradable implants. However, the development of Mg alloys for clinical application continues to be hindered by high corrosion rates and localized corrosion modes, both of which are detrimental to the mechanical integrity of a load-bearing temporary implant. To overcome these challenges, technologies have been developed to improve the corrosion resistance of Mg alloys, among which surface treatment is the most common way to enhance not only the corrosion resistance, but also the bioactivity of biodegradable Mg alloys. Nevertheless, surface treatments are unable to fundamentally solve the problems of fast corrosion rate and localized corrosion. Therefore, it is of great importance to alter and improve the intrinsic corrosion behavior of Mg alloys for biomedical applications. To show the significance of the intrinsic corrosion resistance of biodegradable Mg alloys and attract much attention on this issue, this article presents a review of the improvements made to enhance intrinsic corrosion resistance of Mg alloys in recent years through the design and preparation of the Mg alloys, including purifying, alloying, grain refinement, and heat treatment techniques. The influence of long-period stacking-ordered structure on corrosion behavior of the biodegradable Mg alloys is also discussed.

“…Many new magnesium alloys and composites have been produced and evaluated for biomaterial applications (Mueller et al, 2010, Hermawan, Sunil et al, 2014a, Sunil et al, 2014b, Kirkland and Birbilis, 2014, Keim et al, 2011. However, the applications are seriously limited due to the excessively rapid degradation rate in the physiological environment (Staiger et al, 2006, Mueller et al, 2010, Keim et al, 2011, Witte et al, 2006, Wang et al, 2008 (Jinfeng et al, 2014, Zakiyuddin et al, 2014, Gao et al, 2011, Wang et al, 2010. Furthermore, rapid solidification is another effective way to refine the microstructures of Mg alloys (Wang et al, 2010, Willbold et al, 2013, Liao et al, 2012.…”

As a lightweight metal with mechanical properties similar to natural bone, magnesium-based material has been gaining wide popularity. However, the applications are seriously limited due to the excessively rapid degradation rate in the physiological environment, causing the magnesium to degrade faster than the complete rehabilitation of the bone itself. Grain refinement approach is currently the selected approach to obtain a lower degradation rate without adding other element that might be harmful to human body. This paper studies the possibility of reducing biodegradation rate of a biodegradable through reviewing various studies on grain refinement through hot deformation and rapid solidification.
