Crevice corrosion cathodic reactions and crevice scaling laws

Electrochimica Acta, 2009
A numerical model that predicts the rates of metal dissolution and electrolyte composition along the length of a metallic crevice was used to simulate the crevice corrosion of AISI 304 stainless steel. The model considers both the forward and reverse electrochemical reactions that might take place during the corrosion process.

Chemistry of Crevice Corrosion

CORROSION 1974, 1974
Crevice corrosion is one of the forms of occluded cell corrosion (OCC) discussed by B. F. Brown.1 Such cells have been reported widely in the literature. Particular attention is invited to review articles by France2 and by Rosenfeld & Marshakov.3 It is widely believed that crevice corrosion cells may be categorized as concentration cells of various

Crevice Corrosion Products of Dental Amalgam

Journal of Dental Research, 1991
The objective of this study was to determine the in vitro corrosion products that resulted from crevice corrosion of low-and high-copper dental amalgams. Specimens were potentiostatically polarized in a chloride-containing electrolyte while set against a PTFE surface to form a crevice.

Crevice corrosion in orthopedic implant metals

Journal of Biomedical Materials Research, 1977
AbstractStudies of orthopedic implant alloys in crevice configuration suggest that cobalt‐chromium alloys such as Haynes‐Stellite 25 are the best choice for multicomponent implants. It is also shown that severe crevice attack may result from use of mixed metals.

Fretting corrosion accelerates crevice corrosion of modular hip tapers

Journal of Applied Biomaterials, 1995
AbstractThe use of multiple‐component systems in orthopedic surgery gives the surgeon increased flexibility in choosing the optimal implant, but introduces the possibility of interfacial corrosion. Such corrosion could limit the longevity of prostheses due either to tissue reactions to corrosion products, or to device failure.

Crevice Corrosion of Titanium

1968
Crevice attack of titanium and its alloys has been observed in high-temperature chloride solutions, chlorine gas, and certain acid environments. In chloride solutions, the attack becomes more severe as concentration and temperature increase. For chlorine gas, water is found to be an effective inhibitor.

Microfabrication of Crevice Corrosion Samples

MRS Proceedings, 2000
ABSTRACTA major challenge in developing computer models for crevice corrosion lies in fabricating appropriate experimental crevice samples. The geometry and dimensions of these samples must be controlled to a high order of precision in order to be amenable for comparison to computational models.

Area Effects in Crevice Corrosion

Corrosion, 1951
Specimens of stainless steel were prepared to provide an experimental approximation of a crevice relatively small with reference to the area outside exposed to the corrosive. Test panels were exposed to running fresh sea water for 87 days. Data secured confirmed the expectations the extent of attack within a crevice was proportional to ...

Crevice corrosion and microthrowing power

Journal of Electroanalytical Chemistry and Interfacial Electrochemistry, 1984
Abstract The two concepts of crevice corrosion and electrolytic microthrowing power seem to have been connected very seldom, in spite of the fact that, on a closer look, microthrowing power would be expected to be a decisive factor in crevice corrosion of stainless steels.
