等离子喷涂涂层是由大量熔融熔滴连续沉积而成，形成层状结构。因此，了解熔滴与基体之间的相互作用是非常重要的。western是控制相互作用的因素之一。本文研究了熔融金属液滴对基体的润湿性对溅射平面化程度的影响。使用液滴的自由下落装置，金属Sn、Pb、Cu和Fe用于实验。将金属平衡接触角引入熔滴撞击能量平衡中，在某些区域，理论与实验结果基本吻合。
Plasma sprayed coatings are formed by a continuous deposition of numerous and molten droplets, which lead to a lamella structure. So it is very crucial to understand the interaction between molten droplets and substrates. Wettability is one of the factors governing the interaction. This report presents the influence of wettability of substrates by molten metal droplets on the flattening degree of splats. Using a free-fall apparatus of droplets, the metals, Sn, Pb, Cu and Fe are used for the experiments. Taking an equilibrium contact angle of metals into the energy balance for impingement of molten droplets, the relationship between the theoretical and experimental results shows approximately a good agreement in some Reand Weregions.
