dc.description.abstractSurface chemistry and morphology play a significant role in affecting the wettability of engineering surfaces. To create functional surfaces that are hydrophobic or superhydrophobic, these properties must be understood and controllable. The purpose of this study is to understand the relationship between surface roughness and contact wettability. For this purpose, samples were prepared by using different steel alloys and etched at different etching durations in a mixed solution. The mixed solution for roughening process was prepared by keeping the molar ratio of nitric acid and hydrogen peroxide constant at 1:1, 1:2 respectively. The steel substrates were then immersed in another mixed solution of stearic acid and N, N'-dicyclohexylcarbodiimide in n-hexane (5 mmol/L) for 24 h to lower the surface energy of steel alloy surfaces after roughening step. The effects of the duration of chemical etching on surface roughness were evaluated by using profilometer and surface contact angles were measured using the sessile drop method. Surfaces were analyzed using scanning electron microscopy. Steel surfaces were changed from hydrophilic to hydrophobic/superhydrophobic. The obtained maximum contact angle was 168.36 degrees for CK40 samples, 161.99 degrees for CK22 samples, and 166.35 degrees for 5t37 steel samples. The results of this study showed that the surface contact angle was very sensitive to the change of surface roughness, and wettability could be controlled by changing the surface roughness. In addition, the surface roughness values of steel substrates that exhibit superhydrophobic behavior varied according to the steel type.en_US
