The invention pertains to the use of an ice-phobic coating layer for de-icing or anti-icing of technical aerospace equipment such as aircraft's carburettor(s), pitot tubes, engines and parts thereof, and the rotor blades and generators and parts thereof of wind turbines, and wherein said coating layer: a) exhibits sessile water drop contact angle of at least 75° and a difference in dynamic water drop contact angle of at most 30° , more preferably at most 25° (i.e. low wetting hysteresis), at ambient air conditions, said contact angles measured according to ASTM D7334-08; b) exhibits micro hardness of at least 200 HV (Vickers units) if exposed to fluid velocities lower than 50 m/s and/or micro hardness of at least 800 HV, preferably at least 1000 HV, if exposed to fluid velocities higher than 100 m/s (representing aircraft wing conditions), said micro hardness measured according to ASTM E384-08, and/or exhibits a micro hardness of Ra less than 0.5 μm; c) exhibits corrosion rate of less than 0.1 μm/year; d) is chemically inert; and e) has a mechanical strength in terms of pull-off force/surface unit of more than 10 MPa, preferably more than 20 MPa, measured according to ASTM D4541-09e1.
