On the surface of zirconium alloy, the TiN coatings with and without Cr interlayer were prepared in the N 2 /Ar mixed gas atmosphere by physical vapor deposition technology. The coatings morphology, micro-composition of surface particles, surface roughness, phase constituent and high-temperature oxidation resistance were characterized by scanning electron microscope (SEM), energy dispersive spectrometer (EDS), roughness measuring instrument, x-ray diffractometer (XRD) and chamber electric furnace, respectively. The results show that, in compari...
