Combining the Ohmic Drop and Critical Crevice Solution Approaches to Rationalize Intermediate Attack in Crevice Corrosion
Crevice corrosion material loss is often most severe at intermediate distances into the crevice. This intermediate attack can be rationalized using the ohmic drop model of Pickering if and only if the material in question exhibits active/passive behavior in the crevice environment. Conventional theories that ascribe control of crevice corrosion to chemical changes exclusively cannot rationalize...
متن کاملCombining Rigorously Controlled Crevice Geometry and Computational Modeling for Study of Crevice Corrosion Scaling Factors
Microfabrication methods have been used to construct crevice formers of rigorously controlled gap and length. These have been used to study the IR-controlled crevice corrosion of Ni200 in 0.5 M H2SO4 to determine the effect of crevice gap ~G! on the position of the accelerated attack (xcrit) within the crevice. The experimental results were then compared to the results of computational studies....
متن کاملMapping the concentration changes during the dynamic processes of crevice corrosion by digital holographic reconstruction
The dynamic process of crevice corrosion during anodic dissolution of a crevice electrode in a 5.0 mmol dm-3 NaCl solution has been studied by digital holographic reconstruction. Digital holographic reconstruction has been proved to be an effective and in situ technique to detect the changes in the solution concentration because useful and direct information can be obtained from the three-dimen...

Crevice Structures in Hemoprotein Reactions.
The hemoproteins are such versatile oxidation-reduction catalysts and such remarkable oxygen-binding pigments that there has always been a lively interest in the structural factors that determine the reactivity of the heme iron atom. The high specificity which characterizes many of their reactions, which is shown in only a rudimentary manner by heme itself, would appear to rule out structures w...
