Abstract

Abstract

For systematic review of the high-temperature oxidation resistance of Cr-coated Zirconium alloy fabricated by multi-arc ion plating, the oxidation behavior during the steam oxidation of Cr coating at 800-1400°C was studied. The oxidation weight gains were obtained by simultaneous thermal analyzer. The X-ray diffractometer was used to analyze the phase structure, the scanning electron microscope was used to analyze the surface morphology and thickness of each film in cross section, and the energy dispersive spectrometer was used to analyze the element distribution. The dense Cr₂O₃ scales were formed on Cr coating after the steam oxidation at 1200℃, and the good interfacial bonding quality were observed between coating and substrate, as well as the residual Cr coating on Zr substrate were remained, and the residual Cr coating on Zr substrate were remained. The Cr coating could protect substrate for a short time at 1300℃ steam, but quickly lost its protection at 1400℃ steam. The Cr-coated Zirconium alloy has excellent high temperature oxidation resistance, and it still has good protection on substrate after the steam oxidation at 1200℃.
