摘要：
A Ni-20Cr nanocrystalline coating was obtained by means of magnetron sputtering. The oxide composition of the Ni-20Cr alloy and its nanocrystalline coating after treatment in air at 1000degreesC was analysed. The results indicated that the oxide scale formed on Ni-20Cr alloy is composed of two layers. The external layer consists of NiO containing some Cr2O3 particles and the internal layer is continuous Cr2O3 with a little NiCr2O4, whereas the scale formed on the sputtered Ni-20Cr nanocrystalline coating consists mainly of Cr2O3 with a little NiCr2O4. The mechanism for the effect of nanocrystallisation on the oxidation of the Ni-20Cr alloy is discussed.
