| Abstract: |
Superhydrophobic coatings have displayed significant potential for mitigating icing problems in aerospace applications. Commercially available superhydrophobic sprays are typically polymer-based that have poor durability and thus are rarely used for anti-icing purposes. In this work, suspension plasma sprayed (SPS) superhydrophobic coatings with submicron and nano-structures are developed. These coatings show contact angles higher than 150° and sliding angles lower than 10° which is very desirable for anti-icing applications. The surface morphology and composition of these coatings are characterized using X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy (SEM). The durability of these coatings is tested through water erosion tests. Furthermore, the icing performance of the coatings is investigated by exposing them to icing conditions in a wind tunnel. The results are compared to other superhydrophobic coatings and conventional surface finishes.
