Shadow corrosion or crevice corrosion?

Journal of Nuclear Materials, 2001
Local corrosion phenomena in proximity to other components may have different reasons. In narrow gaps, crevice corrosion can be formed under BWR and to a lesser degree under PWR conditions independent of the counter material. At positions, where dissimilar metals are close to Zry under oxidizing conditions, shadow corrosion, driven by large potential ...

A Crevice Corrosion Cell Configuration

Journal of Dental Research, 1979
An occluded corrosion cell configuration and polarization program were developed in order to measure the crevice corrosion resistance of implant alloys. 316 L stainless steel was used in establishing that the crevice cell configuration was convenient, reproducible, free of unwanted crevices, and suitable for laboratory measurements requiring ...

Modelling Crevice Corrosion

CORROSION 1992, 1992
Abstract An improved mathematical technique has been developed for the numerical simulation of the incubation period of crevice corrosion. The model utilizes an iterative fully-implicit finite difference method coupled with a modified fractional- step decoupling technique to solve the mass transport section of the model. This produces an

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.
