Super-Hydrophobic Surface Prepared by Lanthanide Oxide Ceramics Deposition Through PS-PVD Process Available to Purchase

In this study, superhydrophobic samaria-doped ceria coatings are produced by plasma spray physical vapor deposition (PS-PVD) followed by fluorination treatment. Samples are sprayed at distances of 300, 400, and 500 mm in order to obtain surfaces with different morphology. SEM examination shows that the surfaces have a hierarchical structure with island-like features consisting of nanoparticles, the size of which is shown to influence sliding behavior. The superhydrophobic coating surfaces also exhibited good stability in repeated adhesive-tape tear tests.
