The accumulation of ice presents significant challenges to operators, e.g., in marine environment and energy industries. Removing the accumulated ice consumes valuable resources in terms of time, energy and labor. Avoidance of these costs is possible by developing passive icephobic coating methods. One approach to exploit the passive methods in producing ice repellent surfaces is to use slippery surfaces that combine a porous solid material with a lubricating component. This study presents a novel method in creating functional slippery liquid infused porous surfaces (SLIPS) by utilizing thermal spraying. Functionality and icephobic behavior of these thermally sprayed SLIPS were investigated with cyclic ice adhesion tests along with wettability measurements. The ice adhesion results confirmed the potentiality of thermally sprayed SLIPS as ice repellent surfaces with an order of magnitude lower ice adhesion strength than in mirror polished aluminum.
