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.

薄膜和实心表面之间的相互作用是许多增值工业过程的性能，最著名的是冶金涂层操作。通常，这些操作的速度远远超出了现有型号的范围，从而限制了在操作发生变化或产品质量问题时的价值。现有模型还受到无法说明在整个行业中常用的表面活性剂的存在的限制。这项研究将产生预测分子组成的速度和局部变化如何影响涂层表面的润湿/露水的能力。
