As a result of monitoring the published scientific and operational data on damage heat-exchange of steam-generating it is established, that a major factor which causes damage is electrochemical corrosion process. Are investigated corrosion properties chromium, the titan and coverings on their basis in environments which in a different measure model possible variants corrosion electrochemical process in ПГВ-1000. The analysis of anodi polarizing curves has shown, that for formation of covers on a basis хрома it is necessary to use chromium cleanliness of 99,98 %. The titan (ВТ-1) and vacuum-arc coverings on his basis have high positive values of potential of a pitting and low values of density of a current of a passive condition that allows to recommend them for use in shielding a surface heat-exchange tubes. The carried out researches show an opportunity of transition to the following stage of works on realization protection THAT from electrochemical destruction, namely, statement of the protected pieces of pipes on long-term tests in operating conditions of a steam and gas generator.
