REDUCED FLUID DRAG ACROSS A SOLID SURFACE WITH A TEXTURED COATING
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%...

| description | 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 60%. 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 a such an article are also provided.
La présente invention concerne un article comprenant un substrat avec un revêtement présentant des aspérités de sorte qu'un espacement moyen entre les aspérités soit entre environ 0,01 et environ 1,5 micron. Une rugosité superficielle moyenne du revêtement peut aller jusqu'à 2 microns, et une porosité moyenne du revêtement est dans la plage allant d'environ 35 % à environ 60 %. Un matériau pour réduire l'énergie en surface est disposé sur le revêtement. La présente invention concerne également un procédé permettant de fabriquer ledit article et un procédé permettant de diminuer la traînée de fluide à travers ledit article. |
