Abstract

An electrochemical method for the detection and quantification of Laves phase in 12Cr martensitic stainless steel is proposed in the present work. Laves phase dissolution peak can be observed at the lower potential range which can be obtained in anodic polarization curves in a specific solution with specific pH values. The amount of Laves phase was calculated by the integration of anodic current with time according to the polarization curve and also independently measured by using scanning electron spectroscopy. A good correlation of these two methods was obtained.
