Abstract

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

摘要

我们研究了纯金属体系和合金金属体系中的平衡润湿行为以及前驱体膜的生长。这些体系呈现出平衡的“伪部分”润湿，即一种在液态和固态下均与非零接触角达到平衡的薄膜。膜的铺展动力学清楚地表明了一种扩散传输机制。合金化对平衡润湿性能的影响很小，但对前驱体膜生长过程中的传输有强烈影响。
