METHOD FOR DIRECTLY DETECTING CORROSION ON CONDUCTIVE CONTAINERS

摘要

METHOD FOR DIRECTLY DETECTING CORROSION ON CONDUCTIVE CONTAINERS There is disclosed a method for directly detecting corrosion on the walls of conductive containers wherein a transmitting antenna induces a current into a portion of the container wall and the decay of the induced current is detected by a receiving antenna, with a record of the decay of the induced current being created. The record is interpreted to determine the presence or absence of a corrosion component, with the corrosion component being caused by the presence of corrosion products having superparamagnetic properties.
