“…Ce conversion coatings have been investigated for corrosion protection of different surface-active metals and alloys [28][29][30][31][32], including Mg alloys [21,33]; however seldom they have been used to protect Mg-RE alloys [34,35]. Several works show that the top-view of the conversion layer completely covering the substrate is cracked, exhibiting a socalled dry mud appearance, which some authors claim to be composed of a bi-layered structure [36,37].…”

“…Heating metal components above their melting point (typically between 470 and 750 °C) in a vacuum or under Ar, SF 6 , or CO 2 atmosphere, pouring the molten metal into suitable molds (e.g., steel or graphite), and permitting consolidation are all part of the procedure. Resistance and induction melting furnaces are the foremost common types of melting furnaces [ 114 , 115 , 116 , 117 ].…”

Zinc (Zn)-based biodegradable materials show moderate degradation rates in comparison with other biodegradable materials (Fe and Mg). Biocompatibility and non-toxicity also make them a viable option for implant applications. Furthermore, Pure Zn has poor mechanical behavior, with a tensile strength of around 100–150 MPa and an elongation of 0.3–2%, which is far from reaching the strength required as an orthopedic implant material (tensile strength is more than 300 MPa, elongation more than 15%). Alloy and composite fabrication have proven to be excellent ways to improve the mechanical performance of Zn. Therefore, their alloys and composites have emerged as an innovative category of biodegradable materials. This paper summarizes the most important recent research results on the mechanical and biological characteristics of biodegradable Zn-based implants for orthopedic applications and the most commonly added components in Zn alloys and composites.

A damping alloy with a nominal composition of 50Al-49.9Zn-0.1Ce (at%) was tested in hot compression (60% depression) using a Gleeble-3800 thermomechanical simulator at deformation temperatures and strain rates ranging from 573 to 648 K and 0.01 to 10 s ¹1 , respectively. According to the true stress-strain curves, two constitutive equation models based on peak stress and strain compensation were constructed. The microstructure of the alloy after deformation was characterized and analyzed by means of X-ray diffractometer (XRD), scanning electron microscope (SEM) and energy dispersive spectrometer (EDS). The results show that the flow stress increases with decreasing deformation temperature and increasing strain rate. The theoretical predictions of the constitutive equation model at low temperature and high strain rate are well fitted to the measured values with low average absolute relative errors. At low strain rates and high temperatures, the ¡ + © eutectoid structure tends to transform from lamellar to granular morphologies, which is accompanied by the increased sizes of ¡ and © phases. Also, the obvious dissolution of © into ¡ phase has been occurred and some tiny holes induced by thermal-force coupling have been formed during compression. In this work, the Al-Zn-Ce damping alloy is more suitable for thermomechanical processing at relatively lower temperatures and meanwhile higher strain rates (such as at 573 K/0.1 s ¹1 , 573 K/10 s ¹1 and 623 K/10 s ¹1 ).
