The interaction between thin films and solid surfaces underpins the performance of a number of value-adding industrial processes, most notably metallurgical coating operations. Typically, these operations are performed at speeds well beyond the range of existing models, thereby limiting their value when changes in operation occur or when there are problems with product quality. Existing models are also limited by their inability to account for the presence of surfactants commonly used throughout industry. This study will produce a capability for predicting how velocity and local changes in molecular composition affect the wetting/dewetting of coated surfaces.

薄膜和固体表面之间的相互作用支撑着许多增值工业过程的性能，最显著的是冶金涂层操作。通常，这些操作的速度远远超出现有模型的范围，从而在操作发生变化或产品质量出现问题时限制了它们的价值。现有的模型也受到限制，因为它们无法解释整个行业中常用的表面活性剂的存在。这项研究将产生一个预测速度和分子组成的局部变化如何影响涂层表面的润湿/去湿的能力。
