Abstract

The advantage of using MultiPotential Test, MPT, method together with, for example, double U-bend specimens is that in a single exposure a wide variety of corrosion phenomena can be screened in any environment. The MPT method has been applied in several tests both in simulated environments and in real process conditions. The measurement of threshold potential for stress-corrosion cracking of cold deformed and sensitized stainless steels in simulated boiling water reactor environment (BWR) is an example of successful applications of the MPT method. The MPT method applies a current source combined with potentiostat and resistors to polarize different specimens to desired potentials. The electrochemical potential range, which can be obtained, depends on the electrical instrumentation and also on the conductivity of the electrolyte.
