The as received AZ91D Mg alloy was coated by ZrO2 and ZrN ceramic using Physical Vapour Deposition (PVD) process. dry sliding wear studies were carried out in a pin-on-disc tester at speed of 2-8 m/s normal loads 2- 10 N. mechanism such abrasive, delamination, thermal softening oxidation observed. results showed that the PVD coating increased resistance alloy. worn surface examined Scanning Ele...

magnesium is extracted with a chloroform solution of n-p-tolyl-2- thenohydroxamic acid (pttha) from aqueous solution of ph 9.5 .mg-pttha complex is colourless and the colour is developed by adding quinalizarin into the extract. lmax and e of the complex are 590nm and 2.8´103 lmol -1cm-1respectively.most common  ions do not interfere in the determination of magnesium. the spectral characteristic...

UNLABELLED The dynamic loading in human body, along with the corrosive body fluid, presents a great challenge for the practical use of biodegradable magnesium implants. In this study, a high purity magnesium (99.99wt.%) and two typical promising biodegradable magnesium alloys (binary Mg-1Ca and ternary Mg-2Zn-0.2Ca) were chosen as the experimental materials. Their dynamic mechanical performance...

MAGNEZIX® (Syntellix AG, Hanover, Germany) is a biodegradable magnesium-based alloy (MgYREZr) which is currently used to manufacture bioabsorbable compression screws. To date, there are very few studies reporting on a limited number of elective foot surgeries using this innovative implant. This case report describes the application of this screw for osteochondral fracture fixation at the humera...

Surface nanocrystallization using a surface mechanical attrition treatment effectively activates the surface of magnesium alloys due to the increase in grain boundary diffusion channels. As a result, the temperature of subsequent surface alloying treatment of pure Mg and AZ91 alloy can be reduced from 430 degrees C to 380 degrees C. Thus, it is possible to combine the surface alloying process w...

Tensile test on smooth and circumferentially notched specimens, systematic observation of fracture surfaces and large deformation finite element analysis were conducted to understand the deformation and failure behavior of a magnesium alloy (AM60). The plastic deformation is considered to be dominated by twining mediated slip. The tensile properties were not sensitive to the strain rates applie...
