The results of investigations into the influence of the ion-plasma treatment (IPT), including the ion implantation and ion-plasma coating deposition, on the mechanical properties and corrosion resistance of nuclear fuel cladding tubes made of zirconium alloy (Zr1%Nb) are presented. The tests of cladding samples have been performed at two temperatures between 20 and 350 °С. It is shown that the deposition of TiN, Ti+TiN, TiAlN, TiAlSiN, TiAlYN coatings improves mechanical properties of the sample surface, as well as, leads to the hardening of Zr1%Nb fuel cladding as a whole. The efficiency of hardening by implantation with (Zr, Mo) and gaseous (N₂, O₂) ions depends on the kind of ions and their energy. The nanostructure TiAlSiN and TiAlYN coatings improve the corrosion resistance of zirconium alloy. The results of experiments on hardening of fuel cladding tubes are explained by the state of the coating-surface interface.
