“…Lv et al investigated the wetting characteristics of Al droplets on SiC surfaces and found a strong correlation between the contact angle of molten Al droplets and the interfacial energy. 17 Lv et al investigated the aggregation and wetting mechanisms of aluminum molten droplets on different carbonaceous substrates and showed that different properties of the carbon substrate affect the contact angle. 18 From the above studies, it is found that the studies on the effect of surface morphology on the wetting characteristics of droplets mainly focus on water droplets at room temperature, while the main studies on the wetting characteristics of molten aluminum droplets at high temperatures mostly focus on smooth substrates.…”

To solve the adhesion problem between molten aluminum and vacuum ladle liner during the electrolytic aluminum production process, the wetting state and adhesion properties of molten aluminum droplets on substrate surfaces with different nanopillars are investigated based on molecular dynamics. The results show that the adhesion strength of molten aluminum droplets in different wetting states has the pattern Young state > Wenzel state > Cassie state. Effects of increasing nanopillar height or interval are poles apart in the wetting state and adhesion characteristics of aluminum molten droplets. The critical height and critical interval of the nanopillar where the wetting state transition occurs are obtained. The increase of the nanopillar width can induce the wetting state transition from the Cassie state to the Wenzel state. In addition, the phantom wall method is applied to study the variation of the separation force. It is found that a peak in the separation force curve occurs when the molten droplet separates from the bottom of the nanopillar interval or the top of the nanopillar. The separation force curves of the droplets in the Young state and the Cassie state have single peaks, while the droplets in the Wenzel state have double peaks.

“…1, mostly because of the various SiC substrate types used in these studies. In the case of SiC single crystal, [12][13][14][15][16] Shen et al 15 have demonstrated that the wettability of SiC was inuenced by its surface polarity. The contact angle on the C-terminated surface is smaller than that on the Si-terminated surface of the (0001) crystal plane.…”
