Abstract (en)
[origin: US4632734A] Niobium is electrochemically or chemically coated by subjecting work pieces made of niobium to a blast treatment with aluminium oxide, a treatment with an alkaline cyanide bath, a preliminary nickel deposition treatment using an acidic nickel chloride bath, another treatment with an alkaline cyanide bath, and thereafter to an electrochemical or chemical coating treatment with the desired metal in a per se known manner. To properties of the coatings, more specifically, satisfy the requirements as set for supra-conductive materials.
