Abstract The problem of insulation voltage selection in potential-difference detection method performance electrical insulating metal pair flowing seawater is discussed. In seawater, 921A-B10 was taken as the research object to design corrosion test material. natural test, galvanic and simulated material were carried out respectively. shows that larger analog resistance series is, smaller curre...

The localized corrosion behavior of a galvanic aluminum copper couple was investigated by in situ fluorescence imaging with a fiber-optic imaging sensor. Three different, but complementary methods were used for visualizing remote corrosion sites, mapping the topography of the metal surface, and measuring local chemical concentrations of H+, OH-, and Al3+. The first method is based on a pH-sensi...

Abstract In a quest for better understanding of the mechanism and contribution(s) fresh (“un-degraded”) degraded CFRP surfaces to galvanic corrosion coupled metals in multi-material assemblies electrochemical behaviour quiescent 50 mM NaCl was studied using techniques. Tests ferricyanide/ferrocyanide redox couple revealed quasi-reversible behaviour. Under cathodic polarization, is active electr...

The successful development of scanning probe techniques to characterize corrosion in situ using multifunctional probes is intrinsically tied to surface topography signal decoupling from the measured electrochemical fluxes. One viable strategy is the shear force controlled scanning microcapillary method. Using this method, pulled quartz micropipettes with an aperture of 500 nm diameter were used...

• Hybrid sputtering/ gas agglomeration system produces bimetallic Zn-Fe NPs as oxygen scavengers. The atomic arrangements of the allow to control oxidation mechanism. Galvanic couple between Zn –Fe accelerates process. Molecular dynamic simulations show effect galvanic for Bimetallic nanoparticles (NP) have demonstrated outstanding multifunctional characteristics, which depend on their size, di...

INTRODUCTION: Cannulated screws, along with guide wires, are commonly used for a variety of orthopedic indications. Typically they are used for fractures in cancellous regions. Breakage or bending deformation of the guide wire is a clinical concern. Therefore it would be advantageous to use Co-Cr alloys such as MP35N and L605 in these applications as the occurrence of breakages and bendings wou...
