Abstract:
The isothermal and cyclic oxidation behaviors of bulk pure nickel and its magnetically sputtered Ni-0.5Y micro-crystal coating were studied at 1 000 ℃ in air. Scanning electronic microscopy(SEM)and transmission electronic microscopy(TEM)were used to examine structures of the coating and the NiO oxide films. Laser Raman spectrum was also used to measure the stress level in NiO films formed on bulk nickel and the coating. It was found that Ni-0.5Y micro-crystal coating had lower oxidation rate, and the grain-size of NiO formed on Ni-0.5Y coating was 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 oxide film’s high temperature plasticity was improved in the coating case. The improvements of anti-oxidation properties of the sputtered Ni-0.5Y coating were due to the micro-crystal structure and the rare earth element Y.
研究了纯镍及其表面磁控溅射Ni-0.5Y微晶涂层在1 000 ℃空气中的恒温氧化和循环氧化行为.通过扫描电镜(SEM)和透射电镜(TEM)对涂层以及表面NiO氧化膜的形貌和结构进行了研究.此外, 用激光拉曼(Raman)谱对2种样品表面NiO氧化膜内应力大小进行了测量, 结果表明:Ni-0.5Y微晶涂层与基体镍相比有更低的氧化增重速率, 表面NiO氧化膜的晶粒尺寸明显减小, 膜的高温塑性得以改善.同时, 氧化膜内的压应力水平也有所降低, 因而改善了NiO氧化膜的粘附性和保护性.磁控溅射涂层的微晶结构以及稀
