Abstract

We study the composition of surface films and deposits in corrosion cracks that appear in the stud holes of the flanges of collectors of steam generators of nuclear power stations. The corrosion cracking susceptibility of 08Kh18N10T austenitic steel is found under conditions of cyclically varying temperature under the attack of water, chloride, alkaline, and boric acid solutions, etc. Data of electrochemical investigations are presented. We also determine local concentrations of residual hydrogen and the type of structural transformations. It is shown that fracture of collector materials is caused by alkaline cracking activated by the local depassivating action of chloride ions.
