摘要	A microcrystalline aluminium film with grain size of about 400 nm was prepared by magnetron sputtering technique. Its corrosion behaviour was investigated in NaCl containing acidic solution by means of potentiodynamic polarization curves and electrochemical noise (EN). The polarization results indicated that the corrosion potential of the sample shifted towards more positive direction, while its corrosion current density decreased compared with that of pure coarse-grain AL The EN analysis based on stochastic model demonstrated that there existed two kinds of effect of microcrystallization on the pitting behaviour of pure aluminium: (1)the rate of pit initiation is accelerated, (2)the pit growth process was impeded. This leads to the enhancement of pitting resistance for the microcrystallized aluminium. (C) 2009 Elsevier Ltd. All rights reserved.
