Detection of structural changes in chromium martensitic steels using electrochemical methods
Original language description
High-alloy martensitic steels are used as construction materials in power generating equipments. The problem of these steels, which are most often alloyed with chromium, molybdenum and tungsten, is a possible increase in structural instability during heat treatment or a long-term heating process. The formation of structural instability causes deterioration of mechanical properties and corrosion resistance and leads to overall shortening of the equipment service life. Chromium and molybdenum are elements, which in alkaline environment can easily pass into a transpassive state, and that can be detected for example on a polarization curve of the material in an appropriate environment. The aim of this work was to confirm the possibilities of using electrochemical polarization as a very simple, non-destructive method of investigation into the formation of structural changes in these materials. Potentiostatic etching was also carried out together with measuring of potentiodynamic curves. Pot
