Abstract
An article includes a substrate with a coating having asperities such that an average spacing between the asperities is between about 0.01 and about 1.5 micron. An average surface roughness of the coating is up to about 2 microns, and an average porosity of the coating is in the range from about 35% to about 70%. A material to reduce surface energy is disposed on the coating. A method for making such an article and a method for decreasing fluid drag across such an article are also provided.
