摘要：
The influence of ion-plasma nitriding time of Zr–1Nb alloy fuel cladding tubes on their resistance to oxidation in water vapor at 600–1200°C was studied. The hardness of the samples along the wall thickness increases from 2 to 3 GPa, and on the surface up to 12 GPa depending on the processing time. The nitrided tubes oxidize much more under cracking and delamination of the oxide layer compared to the initial state.
