ABSTRACT:
The present invention relates to a composite ductile metal foil having an optically black surface comprising a metal foil substrate having a thickness effective for shaping and reshaping; a black chromium surface applied to at least one side of said substrate by electrodeposition; said surface having a solar absorptivity of at least about 0.95; an emissivity in the range of about 0.4 to about 0.8; and an adhesion strength effective to resist spalling when a two inch by two inch sample of said composite foil is subjected to repeated deformation around a one mil diameter mandrel. In a preferred embodiment of the present invention, the substrate is molybdenum.
