	1	Rare earth effects on high temperature oxidation of pure nickel at 1000 ℃显示文摘Isothermal and cyclic oxidation behaviors of pure and yttrium-implanted nickel were studied at 1000℃ in air. SEM andTEM were used to examine the oxide scales formed on nickel substrate. It was found that Y-implantation greatly improved the anti-oxidation ability of nickel both in isothermal and cyclic oxidizing experiments. Acoustic emission (AE) technique was used to study the size and number distribution of defects at the oxide/metal interface. Laser Raman microscopy was also used to study the stress status of oxide scales formed on nickel with and without yttrium. The main reason for the improvement in anti-oxidation and adhesion of oxide scale was that Y-implantation greatly reduced the grain size of NiO and lowered the compressive stress within the scale. In the meantime, Y-implantation inhibited ion diffusion rate in the oxide scale and reduced the size and number of interracial defects, hence remarkably enhanced the adhesion of protective NiO oxide scale formed on nickel substrate.

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