Electrochemical techniques have potential for use in conservation, both to evaluate the
protectiveness of existing coatings on metal artefacts and to evaluate potential new conservation
coatings. Three electrochemical methods have been examined in this study for
their applicability to conservation problems. Corrosion Potential Measurement is simple
but provides only minimal information on the corrosion processes occurring in an electrochemical
system. Electrochemical Impedance Spectroscopy provides both mechanistic
and predictive information on coating performance, but the data are complex to interpret
and measurements require equipment that is at present too bulky for effective on-site use
and beyond the budget of most conservation laboratories. Electrochemical Noise Measurement
can be performed using cheap, portable instrumentation and theoretically requires
relatively simple statistical processing and interpretation, making it attractive for
conservation applications. This project looks at the development of a simple, low cost
electrochemical noise measurement system for conservation needs, and uses it to compare
Electrochemical Noise Measurement with the other two techniques.
