摘要：

The temperature and concentration dependencies of the surface tension of high-purity tin and its alloys with lead were investigated in an ultrahigh vacuum by the large-drop method. It was shown that the tin surface-tension polytherm obeyed the equation sigma(T) = 570.0-0.08(T - T-m). Lead was found to possess high surface activity in the range of its low concentrations in tin. Estimate was made for the limiting lead surface activity in tin-based alloys. Our conclusions about lead surface activity in alloys with tin are consistent with the literature data obtained by the modern electron-spectrometric methods for the surface compositions of the alloys studied.
