Abstract
Methods of treating superconducting composites to enhance their wettability in solder, and composites having enhanced wettability. It has been found that wettability can be substantially enhanced by stripping a thin layer off the surface of the composite before incorporating it into a laminated component. This layer can be stripped, for example, by chemically etching the composite, for example in a solution of nitric acid and ammonium bifluoride.
