چکیده انگلیسی
Nanocrystalline nickel coatings with grain size of 50ânm were annealed in vacuum at 200â°C and 400â°C for 10âmin. Their microstructures were investigated by transmission electron microscopy (TEM). And their corrosion behaviors were studied by means of polarization and electrochemical impedance spectroscopy (EIS). The results showed that their grain size grew up to about 60ânm (200â°C) and 500ânm (400â°C), respectively. The specimen annealed at 200â°C possessed higher density of twins in compared with the counterparts of as-deposited and annealed at 400â°C. The normal grain size effect on the corrosion behavior was not observed. However, it was found that the corrosion resistance of the coating linearly changed with the density of twins.
