Abstract
The electrochemical polarization (ECP) method was verified on specimen s of steam turbine rotors after long time service. Proportionality of differences in the minimum current densities of the specimens from hig h temperature turbine parts and these of the control specimens, to dif ferences of transition temperatures (FATT) was found. That agrees with the results obtained by the Japanese authors of the ECP method [2,3].
