  • Infrared absorbent shield
    Patent number: 5196106
    Abstract: A process for forming an infrared absorbing cold shield which comprises anodizing an aluminum mandrel for the cold shield to provide a porous layer of aluminum oxide over the surface of the mandrel. The anodized mandrel is then immersed in an electroforming solution and metal is electrolytically deposited into and over the aluminum oxide layer. The aluminum mandrel is then selectively dissolved, leaving a metal body of the electroformed metal with a layer of infrared absorbing aluminum oxide mechanically anchored to the interior surface of the metal body.
