In order to measure the potentials associated with metal
structures and piping systems, an analytical model producing
robust numerical algorithms will be developed for evaluating an
impressed current cathodic protection system. The algorithms will
use boundary measurements of potentials to provide solutions to
the inverse problem of determining the conductivity of a bounded
region. The algorithms will be incorporated into a software
package for determinating the effectiveness of cathodic protection
and for quantifying the difference between corrosion-accelerating
potentials and normal non-harmful potentials. The algorithms could
be used to construct diagnostic capabilities to specify which sys-
tems and structures are using different (or no) protection
schemes, which are attached to protected systems, and which must
be isolated to prevent accelerated deterioration of either system.
The application of the software will also result in identifying
alternate protection systems.
Potential Commercial Application:
Potential Commercial Applications: This method can be used for
measuring the effectiveness of the corrosion protection on
underground metal structures and piping. Potential users include
NASA, the oil industry, and municipalities.
