due to good biocompatibility, corrosion and mechanical properties, magnesium (mg) is considered promising degradable material for orthopedic applications. in this work, mg-mgznx (x= 1, 2, 3 and 4) nanocomposites scaffolds with different porosities were synthesized via powder metallurgy method. the microstructure, composition, in vitro corrosion and mechanical properties of porous magnesium-zinc...

tarnish and corrosion behavior of three commercial dental amalgams namely am.1, am.2, am.3, have been investigated by utilizing in vitro tests. the corrosion and/or dissolution rate of the three dental amalgams were studied in 0.9 wt% nacl solution, artificial saliva and ringers solution. potentiodynamic polarization technique was employed to study cathodic and anodic polarization behavior, fro...

the aisi 316 l stainless steel (ss) specimens were exposed to passivation surface through two different processes including; holding in 40-vol% hno3 at temperature of 60 ºc for 30 min and 15-vol%h2so4 at ambient temperature for 1 hour. the corrosion behavior of specimens was evaluated in physiological solutions by electrochemical in vitro tests through linear and tafel polarization tests. cycli...

the commonly used nickel-titanium (niti) archwires in orthodontic treatment are often exposed to fluoride-containing mouthwashes. the aim of this in-vitro study was to evaluate and compare the corrosion resistance of three commercially available niti archwires exposed to 0.05 wt% and 0.2 wt% fluoride mouthwashes.three different types of niti archwires, 0.016″ in diameter, from dentaurum, global...
