Surface‐sensitive x‐ray scattering techniques with atomic scale resolution are employed to investigate the microscopic structure of the surface of three classes of liquid binary alloys: (i) Surface segregation in partly miscible binary alloys as predicted by the Gibbs adsorption rule is investigated for Ga‐In. The first layer consists of a supercooled In monolayer and the bulk composition is reached after about two atomic diameters. (ii) The Ga‐Bi system displays a wetting transition at a characteristic temperature Tw ≈︁ 220°C. The transition from a Bi monolayer on Ga below Tw to a thick Bi‐rich wetting film above Tw is studied. (iii) The effect of attractive interactions between the two components of a binary alloy on the surface structure is investigated for two Hg‐Au alloys.
