High-intensity low energy chromium ions implantation was used for surface modification of zirconium Zr-1Nb alloy. The Cr ions were extracted from cathodic arc plasma and focused ballistically using a negatively biased hemispherical grid electrode immersed in plasma. The microstructure, phase composition and elemental distribution of Cr-implanted alloy were studied by scanning electron microscopy (SEM), X-ray diffraction (XRD) and energy dispersive X-ray spectroscopy (EDX), respectively. The results revealed the formation of ZrCr2 Laves phase of C15 polytype after Cr ions implantation. The content of Laves phase increases with implantation temperature up to 22 vol% (at 900 °C). The Laves phase precipitations are nucleated and grew alternately inside the α-Zr solid solution matrix. The high-temperature (HT) oxidation resistance of Cr-implanted samples was analyzed during HT oxidation test in steam at 1000 and 1200 °C for 10 min.
