Investigation on pre-oxidation of steels in light water reactor circuits Original Research Article

The state of the art of procedures for the generation of high grade corrosion-protective layers is presented. Quality criteria are discussed. The draft concerning the investigation of pre-oxidation of steels by hot water containing dissolved oxidizing agents is pointed out and substantiated. The evaluation of oxide layers generated in that way is difficult and can be carried out only by using several methods in combination. The validity of gravimetric and surface analytical methods is discussed. Preliminary results of experiments on pre-oxidation by hot water containing oxygen are presented and evaluated.
