Abstract

This article presents experimental program, focused on extending lifetime and operation reliability of dissimilar welded joints of austenitic and perlite steel in conditions of secondary circuit media of water–water power reactor (VVER) unit. The main purpose of this experimental program is to bring new possibilities of corrosion protection of dissimilar welded joints, which are threatened by corrosion and degradation processes. These degradation processes significantly affect their service life. Suitability and corrosion behavior of thermal-sprayed coatings were tested.
