Methods and Setups for Corrosion Testing in Moving Media and under Heat Exchange Conditions: 4. Crevice Corrosion

摘要

The possibilities offered by various setups for the investigation of crevice corrosion are considered. It is pointed out that the setups with rotating electrodes, despite their ability to create controlled hydrodynamic and heat exchange conditions, are not suited for studying crevice corrosion because of the forced removal of a medium from the crevice under the action of centrifugal forces. The design of a setup free of this disadvantage is proposed, which employs a combination of rotating and immobile disks.
