摘要： An article comprising a non-conductive substrate having a sub-micron thickness of an oxidizable conductive first metal coating thereon, and a second (promoter) metal which is galvanically effective to promote the corrosion of the first metal, discontinuously coated on the first metal coating. Optionally, the second metal-doped, first metal-coated substrate may be further coated with a salt, to accelerate the galvanic corrosion reaction by which the conductive first metal coating is oxidized. Also disclosed is a related method of forming such articles, comprising chemical vapor depositing the first metal on the substrate and chemical vapor depositing the second metal on the applied first metal coating, and of optionally applying a salt by salt solution contacting of the second metal-doped, first metal-coated substrate. When utilized in a form comprising fine-diameter substrate elements such as glass or ceramic filaments, the resulting product may be usefully employed as an evanescent chaff. In the presence of atmospheric moisture, such evanescent chaff undergoes oxidation of the first metal coating so that the radar signature of the chaff transiently decays.
