STABLE ICEPHOBIC TEFLON-LIKE COATINGS DEPOSITED ON AN ANODIZED ALUMINIUM SURFACE
In order to reduce ice accumulation on the surface of aluminium alloys, an icephobic and superhydrophobic coating was prepared by sputtering Teflon on an anodized aluminium surface. The superhydrophobic film showed an ice adhesion strength reduction of 3.5 times. However, these coatings showed a weak stability after several icing/de-icing cycles. In order to improve the cohesive strength of the Teflonlike coating, the input power of the discharge was increased during the sputtering process. XPS and contact angle analyses showed that an increase in input power renders the Teflon-like coating more stable. Low variations in ice adhesion strength were observed after as many as 9 icing/de-icing cycles.
