Biodegradable materials are under investigation due to their promising properties for biomedical applications as implant material. In the present study, two binary magnesium (Mg) alloys (Mg2Ag and Mg10Gd) pure Mg (99.99%) were used in order compare degradation performance of vitro vivo conditions. analysis cell distribution viability was performed on discs Mg, Mg2Ag Mg10Gd. The results verified viable pre-osteoblast cells all three no obvious toxic effect within first weeks. rates conditions...
An AM60 magnesium alloy nanocomposite reinforced with 1 wt % of AlN nanoparticles was prepared using an ultrasound (US) assisted permanent-mould indirect-chill casting process. Ultrasonically generated cavitation and acoustic streaming promoted de-agglomeration particle clusters distributed the particles throughout melt. Significant grain refinement due to nucleation on accompanied by exceptional improvement in properties: yield strength increased 103%, ultimate tensile 115%, ductility 140%....
Magnesium alloys are promising candidates for biodegradable medical implants which reduce the necessity of second surgery to remove implants. Yttrium in solid solution is an attractive alloying element because it improves mechanical properties and exhibits suitable corrosion properties. Silver was shown have antibacterial effect can also enhance magnesium alloys. Measurements microhardness electrical resistivity were used study response Mg–4Y Mg–4Y–1Ag isochronal or isothermal heat...
This study investigated the effect of biodegradable Mg and alloys on selected properties MC3T3-E1 cells elicited by direct cell/material interaction. The chemical composition morphology surface based (Mg2Ag Mg10Gd) were analysed scanning electron microscopy (SEM) EDX, following corrosion in cell culture medium for 1, 2, 3 8 days. most pronounced difference morphology, namely crystal formation, was observed when Pure Mg2Ag immersed days, associated with an increase atomic % oxygen a decrease...
In situ synchrotron diffraction experiments were performed during Differential Scanning Calorimetry (DSC) of AS31, AS33 and AS35 alloys. The samples encapsulated in stainless steel crucibles the measurement using an empty crucible as reference. heated up to 680°C, melted solidified beginning experiment order fill crucible. This short cycle was followed by three subsequent cycles between 400°C 680°C with 5, 10 20 K/min heating cooling rates 5 min holding time molten state. patterns recorded...
A warm‐drawn Mg6Ag wire with a diameter of 1.6 mm is investigated by immersion tests in Ringer solution two conditions: as‐drawn and heat‐treated wire. The initial condition showed higher strength comparison to the one. As‐drawn has heavily twinned grains. Heat treatment causes slight grain growth, but less microgalvanic corrosion due dissolved second phases significantly reduction twin boundaries. mean rate decreases more than half heat resulting remaining mechanical properties. also time,...
Diamondlike properties of amorphous carbon films can be enhanced by applying reactive hydrogen atmosphere during pulsed laser deposition (PLD) as shown recent studies. The complex phenomena occurring plume expansion has not been examined yet thoroughly. Therefore we deposited hydrogenated thin in ambient (4×10−4–25Pa) PLD at room temperature. were characterized Rutherford backscattering spectrometry, elastic recoil detection analysis, Raman spectroscopy, infrared variable angle spectroscopic...
Abstract Bioresorbable magnesium materials are widely investigated because of their promising properties as orthopedic devices. Pure (99.99%) and two binary alloys (Mg2Ag Mg10Gd) were used to investigate the degradation behavior, bone adherence bone-implant interface mechanics these in growing Sprague-Dawley
Biodegradable Mg alloys are a new class of temporary implant materials for musculo-skeletal surgery. Recent studies show that Mg-based can be biocompatible and there is high demand to design with adjustable corrosion rates suitable mechanical properties. An approach solving this challenge might the use metal matrix composites (Mg-MMC). In study, Mg-MMC composed ZK60 was investigated as base material hydroxyapatite (HA) particles were added tailoring its The composite produced by high-energy...
