Combining 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 کاملCombining 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 کاملEvidence of the Potential Shift Mechanism in Crevice Corrosion (RESEARCH NOTES)
Previous research has indicated a qualitative resemblance between the current distribution along actively corroding crevice walls and currents measured in corresponding anodic polarization plots. Using detailed measurements of the potential gradient along the crevice, a semi-quantitative current distribution was calculated for the crevice wall using a double numerical differentiation method. Th...
متن کاملCrevice 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...
متن کاملCrevice Selection by Octomys Mimax
The viscacha rat (Octomys mimax; Rodentia, Octodontidae) belongs to a monotypic genus endemic to western Argentina and inhabits lowland deserts with abundant rocks and ravines. Our objectives were 1) to determine the attributes of crevices (depth, height, width, entrance orientation, and rock color) that infl uence selection by the viscacha rat; 2) to compare the range and variance of temperatu...
