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 کاملFailure Of Prestressing Steel Induced By Crevice Corrosion In Prestressed Concrete Structures
The application of prestressed concrete technology in civil structures is relatively recent. Therefore, the existing prestressed concrete members in such structure are still relatively young, and the corrosion and the concrete deterioration problems associated with this type of concrete members have became clearly evident only in the early 1980s. Damage during service, frequently appearing afte...
متن کاملEffect of Alloying Elements on Crevice Corrosion Inhibition of Nickel- Chromium-Molybdenum-Tungsten Alloys under Aggressive Conditions: An Electrochemical Study
The effects of Cr, Mo and W on the crevice corrosion of a number of commercial Ni-Cr-Mo (W) alloys in 1.0 mol/L NaCl were studied using the potentiodynamic-galvanostaticpotentiodynamic technique to measure film breakdown and repassivation potentials as well as protection temperatures. As expected, Cr is the key element determining resistance to crevice initiation but a substantial Mo alloy cont...
