We explore the equilibrium wetting behavior and precursor film growth in pure and alloy metallicsystems. The systems exhibit equilibrium "pseudopartial" wetting, that is, a thin film in equilibrium witha nonzero contact angle in both liquid and solid states. The film spreading kinetics clearly indicates adiffusive transport mechanism. The alloying has only a small impact on the equilibrium wetting propertiesbut strongly affects the transport during the growth of the precursor film.
