摘要

The surface tension of several aluminium alloys and the strength of the oxide film formed on them have been measured by the sessile drop technique and a modified-Wilhelmy plate method respectively. This paper describes the methods and equipment employed and the results obtained, with particular emphasis on the effect of alloy composition on these two characteristics. The results are applied to the development of an hypothesis for the formation of as-cast surfaces on vertical direct chill (VDC) cast product.
