ABSTRACT:
An apparatus for measuring the diffusion of hydrogen atoms from a second surface to a first surface of a ferrous metal body in order to monitor the magnitude of corrosion occurring at the second surface. The apparatus comprises a chamber-defining member which can be sealed to the first surface of the body so as to define with the first surface a sealed chamber. The chamber-defining member is constructed of material sufficiently flexible that upon evacuation of the sealed chamber the chamber-defining member deflects toward the first surface to reduce the chamber volume. The apparatus provides a connection for attaching an evacuating pump which is used to evacuate substantially all of the contents of the chamber. A valve is provided to isolate the evacuated chamber from the evacuation pump so that hydrogen atoms, generated as a result of corrosion of the second surface, migrate through the body and exit the first surface within the chamber and combine to form hydrogen molecules which collect in the chamber. A vacuum gauge is provided to monitoring the decay of the vacuum in the chamber over time.
