Description
The influence of a preliminary pulsed plasma treatment on the corrosion resistance of fuel claddings of EP823 (16Cr12MoWSiNbVB)ferritic-martensitic steel in liquid lead in conditions of static and dynamic tests has been investigated. It has been obtained that modifying the structure-phase state of the surface layers by pulsed plasma decreases the corrosion layer thickness (i.e., the oxide film thickness) more than twice. The post graduation annealing of samples before the corrosion tests results in an additional decrease of the oxide film thickness and and an increase of the corrosion resistance more than three times, at that the averaged corrosion velocity of modified samples in liquid lead at temperature 650 degree C for 1000 h decreases up to 4.5 compared to ∼14 nm/h for standard fuel tubes
