Zusammenfassung:	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. L'invention concerne une méthodologie d'application en revêtement et de finition de surface qui fournit un produit en aluminium d'apparence supérieure ayant une performance contre la corrosion acceptable pour une utilisation extérieure. Selon un mode de réalisation, un revêtement d'aluminium haute pureté est appliqué en premier sur un article ou produit d'aluminium via une pulvérisation à froid ou thermique, et la modification de surface mécanique (par exemple polissage, tamponnage, brossage, etc.) est effectuée en deuxième. Le produit résultant a le poids léger souhaitable et des propriétés mécaniques de l'aluminium souhaitables, avec l'apparence et la performance choisies du revêtement d'aluminium haute pureté. Le produit d'aluminium devant être recouvert peut être obtenu par exclusion, forgeage, coulée ou laminage.
