Mining Conditions Passivation on Steel Pipe Heaters Steam Generator NPP


Issue of journal:


Electrochemical studies conducted on samples of pipe heaters steam generators made of steel
08Х18Н10Т not of used after washing with acid solutions and complexing with various additives
followed by passivation or without passivation. Found that the best passivation marked processing
samples in solutions containing aluminum nitrate – a stationary potential, while in comparison with
the investigation of shifts to a more positive region, which indicates the high shielding of active
sites on the surface of the metal.
