Abstract
The characteristics of oxide films formed within a short time of pouring were investigated using samples prepared via the oxide–metal–oxide sandwich (OMO) technique. Surfaces of the OMO sandwiches were studied using scanning electron microscopy. The thickness of the folds of oxide films was examined and compared with previously obtained values for Al–7Si–0··4Mg and Al–5Mg alloys. Results showed that the thicknesses of oxide films formed in pure aluminium and Al-7Si- 0.4Mg alloy are very close and in the range 100-500 nm.
