In this study, magnesium-zinc (Mg-Zn) alloy was investigated as a biodegradable orthopedic implant. MC3T3-E1 cell attachment, mineralization and osteogenic-specific mRNA expression were assessed for as measurements of the in vitro biocompatibility of Mg-Zn alloy. In vivo degradation of the Mg-Zn alloy and the accompanying new bone formation in the femoral marrow cavity were analyzed by scanning...

Porous biodegradable Mg and its alloys are considered to have a great potential serve as ideal bone substitutes. The recent progress in additive manufacturing (AM) has prompted application fabricate scaffolds with geometrically ordered porous structures. Extrusion-based AM, followed by debinding sintering, been recently demonstrated powerful approach fabricating such scaffolds, which can avoid ...

A strategy of suppressing the fast degradation behaviour of Mg-based biomaterials by the introduction of one of Mg degradation products Mg(OH)2 was proposed according to the following degradation mechanism, Mg + 2H2O ⇋ Mg(OH)2 + H2↑. Specifically, Mg(OH)2 submicron particles were mixed into poly (L-lactic acid) (PLLA) to synthesize a composite coating onto hydrofluoric acid-pretreated Mg-Nd-Zn-...

Mg-5wt.% Sn alloy is often used in portable electronic devices and automobiles. In this study, mechanical properties of Mg-5wt.% Sn alloy processed by Equal Channel Angular Extrusion (ECAE) were characterized. More precisely, its hardness and wear behavior were measured using Vickers hardness test and a pin-on-disc wear test. The microstructures of ECAE-processed Mg-Sn alloys were investigated ...

In this research, comparative study of corrosion resistance of aluminum based alloys and Al-alloys with nickel have been investigated. Several processes are conducted for the AlZn-Mg-Cu alloys and Al-Zn-Mg-Cu-0.5%Ni alloys were homogenized, aged then retrogressed and reaged; also, alloys were homogenized then the extruded thereafter heat treated. Al-Zn-Mg-Cu alloy and AlZn-Mg-Cu-Ni alloy sample...

Oxidation behavior of metastable mechanical alloys in the Al–Mg binary system has been examined in the context of high-energy density materials and combustion applications. Mechanical alloy powders with compositions ranging from Al0.95Mg0.05 to Al0.5Mg0.5, as well as the component metals, were heated at 20 K/min in oxygen. Differential thermal analysis and thermogravimetric analysis showed that...

Magnesium alloy is a potential biodegradable metallic material characterized by bone-like elastic modulus, which has great application prospects in medical, automotive, and aerospace industries owing to its biocompatibility, lightweight properties. However, the rapid corrosion rates of magnesium alloys seriously limit their applications. This study collected alloys’ data developed model predict...
