摘 要:The isothermal and cyclic oxidation behaviors of bulk pure nickel and its Ni-0.5Ymicrocrystal coating sputtered by magnetron at 1 000 ℃in air were *** scanning electronic microscopy(SEM)and transmission electronic microscopy(TEM)were used to examine the structures of the coating and the NiO oxide *** laser Raman spectrum was also used to measure the stress level in NiO films formed on bulk nickel and the *** is found that the Ni-0.5Y microcrystal coating has lower oxidation rate,and the grain size of NiO formed on Ni-0.5Ycoating is also relatively smaller than that formed on bulk ***,the compressive stress level of oxide film formed on Ni-0.5Ycoating was lower than that formed on bulk nickel,and the high temperature plasticity of oxide film was much improved in coating *** improvements of anti-oxidation properties of the sputtered Ni-0.5Ycoating are due to the microcrystal structure and yttrium.
