| Abstract: | The methods for the research on the electrochemical behaviors within stress corrosion cracks are reviewed,which consisted of pratical and modeled measurements and theoretical alalysis.Three important but unclear problems are also presented,these are processes of electrochemical kinetics at cracktips,the distributions of current and inpedence within cracks and the influence of polarization on the electrochemistry of crack tips. |
