Alloying of Surface Layers of the Fuel Claddings from Sponge Based E110 Alloy to Increase High Temperature Oxidation Resistance

Abstract

The results of experiments of parts of cladding tubes from sponge based zirconium E110 alloy near-surface layers doping by means of ion-plasma technologies are presented in this paper. Alloying of material by method of pre-deposited Fe, Y, Mo, Al, Mg, Cr films ion mixing is performed on installation ILUR-03 by means of radial Ar + ion beam 3-4 keV average energy. State of modified material layer and oxides, grown on the modified samples in argon-water steam mixture at 1200 ∘ C studied by scanning electron and ion microscopy methods, X-ray analysis and secondary ion mass spectroscopy. It is shown that treating modes defined contribute to the barrier for oxygen penetration and material oxidation formation near ion-doped surface.
