Abstract:
Metal sheets and plates having friction-reducing textured surfaces and methods of manufacturing these metal sheets and plates are disclosed herein. In an embodiment, there is provided a transportation vessel that includes at least one metal product having at least one surface that is substantially grooved, wherein the substantially grooved surface forms a riblet topography, the riblet topography including a multiplicity of adjacent permanently rolled longitudinal riblets running along at least a part of the surface, and wherein the riblet topography is coated with at least one coating sufficiently designed and applied to preserve the riblet topography. In an embodiment, the multiplicity of adjacent permanently rolled longitudinal riblets results in a friction-reducing textured surface. In an embodiment, metal product is used in fabricating at least a portion of an aircraft. In an embodiment, metal product is used in fabricating at least a portion of a rotor blade.

Abstract:
A surface finishing and coating methodology that provides a superior looking aluminum product with acceptable corrosion performance for outdoor use. In one embodiment, a coating of high purity aluminum is applied first to an aluminum article or product via cold or thermal spray and the mechanical surface modification (e.g., polishing, buffing, brushing, etc.) is done second. The resulting product has the desirable light weight and mechanical properties of aluminum with the chosen look and performance of the high purity aluminum coating. The aluminum product to be coated may be obtained by extrusion, forging, casting, or rolling.

Abstract:
Una nave de transporte caracterizada por que: - al menos un producto metálico que tiene al menos una superficie que es básicamente ranurada, en donde la superficie básicamente ranurada forma una topografía de microsurcos, incluyendo la topografía de microsurcos una multiplicidad de microsurcos longitudinales laminados de forma permanente adyacentes (200, 220, 240, 260, 800, 850) que corren a lo largo de al menos una parte de la superficie, y en donde la topografía de microsurcos está revestida con al menos dos capas que comprenden una capa base y una capa de acabado y en donde estas capas están diseñadas y son aplicadas suficientemente para conservar la topografía de microsurcos, en donde la multiplicidad de microsurcos longitudinales laminados de forma permanente adyacentes (200, 220, 240, 260, 800, 850) resulta en una superficie con textura que reduce la fricción.
