Cannulated screws, along with guide wires, are typically used for surgical fracture treatment in cancellous bone. Breakage or bending deformation of the guide wire is a clinical concern. Mechanically superior guide wires made of Co-Cr alloys such as MP35N and L605 may reduce the occurrence of mechanical failures when used in combination with conventional (316L stainless steel) cannulated screws...

Galvanic manufacturing is widely employed and can be found in nearly every average city in Russia. The release and accumulation of different metals (Me), depending on the technology used can be found in the vicinities of galvanic plants. Under the environmental protection act in Russia, the regulations for galvanic manufacturing do not include the regulations and safety standards for ambient ul...

The artificial hip joints have galvanic couple between femoral head made of CoCr alloy and stem Ti or alloy, are subjected to high levels mechanical stress. Therefore, tribocorrosion has been frequently reported. In this study, we performed the first electrochemical numerical simulation for with friction in simulated body fluid. We constructed single metal model investigate effect cathodic reac...

Electroless nickel (Ni) immersion gold (Au), commonly referred to by the acronym ENIG, is most common protective coating applied on exposed copper (Cu) traces of printed circuit boards (PCBs). In this work, we elucidate local corrosion mechanism ENIG-Cu system applying microscopic, surface analysis and electrochemical techniques with high spatial resolution provide a comprehensive understanding...

We investigated how postural responses to galvanic vestibular stimulation were affected by standing on a translating support surface and by somatosensory loss due to diabetic neuropathy. We tested the hypothesis that an unstable surface and somatosensory loss can result in an increase of vestibulospinal sensitivity. Bipolar galvanic vestibular stimulation was applied to subjects who were standi...

Galvanic Corrosion and Composites. “Galvanic corrosion is an electrochemical process in which one metal corrodes preferentially when it is in contact with a different type of metal and both metals are in an electrolyte [1].” Thus, corrosion of this type is always a concern when two different materials are to be in mutual contact. In the aerospace industry for instance, galvanic corrosion could ...

The general and galvanic corrosion of high strength steel (980), high strength steel (907) and high strength steel (921A) in seawater at elevated temperatures has been analyzed using electrochemical measurements and a zero-resistance ammeter (ZRA). After the tests, the surface morphologies of the samples have been detected by SEM. Results show galvanic corrosion behavior of 980/907/921A fulfill...

Introduction Human multimodal vestibular cortical regions are bilaterally anterior insulae and posterior opercula, where characteristic vestibular-related cortical potentials were previously reported under acoustic otolith stimulation. Galvanic vestibular stimulation likely influences semicircular canals preferentially. Galvanic stimulation was compared to previously established data under acou...
