Porous Anodized Aluminum Surfaces Sealed with Diamond-Like Carbon Coatings

Abstract: 

A component comprising an anodized aluminum surface comprising a diamond-like carbon sealant. In a preferred embodiment, the diamond-like carbon sealant substantially fills pores in the anodized aluminum surface, and the pores are substantially free of gas. The anodized aluminum surface and sealant form an interface which preferably is substantially free of imperfections attributable to water molecules remaining adsorbed to the surface during application of said sealant.
