Amorphous and crystalline magnesium alloys, developed for medical applications – especially implantology – present the characteristics of biocompatible magnesium alloys (Mg-Zn, Mg-Zn-Ca, Mg-Ca etc.). This chapter provides a brief description of the role of magnesium in the human body and the use of Mg in medicine. It presents the concept of using magnesium alloys in medicine (advantages and limitations) and the scope of their potential applications (orthopedic implantology, cardiac surgery etc.). The chapter shows classification of magnesium alloys as potential biomaterials, due to their structure (amorphous, crystalline) and alloying elements (rare earth elements, noble metals etc.). The mechanism and in vitro degradation behavior of magnesium alloys with amorphous and crystalline structures are described. The chapter also discusses the influence of alloying elements (rare earth elements, noble metals) on the in vitro degradation process. It also presents the methods of reducing the degradation rate of magnesium alloys by modifying their surface (application of protective layers).

“…This is due to poor mechanical properties of resorbable biomaterials. Mechanical strength of the resorbable materials used in medicine is 30-100 MPa [10,12]. Consequently, mechanical properties of resorbable polymers and ceramics are a barrier to their use as biomaterial for implants, such as shortterm orthopedic implants.…”

“…Magnesium alloys have been the most studied candidates for such materials [3][4][5][6][7][8][9][10][11][12]; however, their high degradation rate needs to be controlled. The usage of Ca-Mg-Zn ternary alloy is as the focus of an alternative strategy [13][14][15][16][17][18][19][20][21][22][23][24][25] as it contains Ca, which is an essential element for living organisms, and Zn, which exists in trace amounts in the body. Zn is considered an essential mineral in the human body, and it is important for the proper functioning of numerous enzymes and for supporting immune functions, protein and DNA synthesis, and wound healing [7,26].…”

In this paper, in order to achieve the development of a novel biodegradable dual-phase alloy in a Ca–Mg–Zn system, the establishment of the control strategy of degradation behavior of alloys composed of two phases was attempted by the control of alloy composition, constituent phases, and microstructure. By combining two phases with different dissolution behavior, biodegradable alloys are expected to exhibit multiple functions. For example, combining a suitable slow dissolving phase with a faster dissolving second phase may allow for dynamical concavities formation during immersion on the surface of the alloy, assisting the invasion and establishment of bone cells. Without the careful control of the microstructure, however, there is a risk that such dual-phase alloy rapidly collapses before the healing of the affected area. In this study, ten two-phase alloys consisting of various different phases were prepared and their degradation behaviors were examined. Consequently, it was found that by combining the IM3 and IM1 intermetallic phases with the compositions of Ca2Mg5Zn13 and Ca3Mg4.6Zn10.4, the expected degradation behavior can be obtained.

“…Among them, the Mg-Zn-Ca alloys have been extensively investigated [8][9][10][11], but their wider biomedical application is limited by hydrogen evolution due to their rapid degradation in physiological environments [12][13][14]. This phenomenon was determined to occur because of corrosion in physiological environments, and many improvements have been proposed to increase the corrosion resistance of the alloys [15][16][17][18].…”

“…It has been established that chemical composition plays an important role in improving corrosion resistance, and alloy elements such as Au, Ag, Ca, Y, or Sr have been shown to improve corrosion resistance [13,15,17,18]. To increase the corrosion resistance of the alloys, protective coatings such as Ca-deficient hydroxyapatite or nano-hydroxyapatite have been also widely investigated [19][20][21][22][23][24][25].…”

In this work, the influence of various volume fractions of the crystalline phase in an amorphous matrix of Mg 67 Zn 29 Ca 4 alloys was investigated for its corrosion resistance for biodegradable applications. An amorphous Mg 67 Zn 29 Ca 4 alloy was successfully fabricated using melt casting into a copper mould. Then, to obtain different ratios of the crystalline phase in an amorphous matrix, the obtained amorphous rods with 3 mm diameters were annealed at 190, 230, 250, and 400°C. The volume fraction of the crystalline phase was measured by X-ray diffraction, and the microstructures of the obtained alloys were determined based on scanning electron microscopy images. Electrochemical testing was conducted in simulated body fluid at 37°C. This report shows that the ratio of the volume fractions of amorphous and crystalline phases in alloy microstructures strongly influences their corrosion behaviours. The alloy with a fully amorphous structure was the most resistive in the analysed media.
