Problems solved by technology

[0002] The electroplating nickel process for superconducting materials is currently a difficult problem that the international electroplating industry is overcoming. Because most superconducting materials are extremely thin in diameter, they cannot withstand the tension of the equipment during the continuous electroplating process (minimal tension may cause deformation or fracture of the material. ), in addition, the electroplating of superconducting materials has very high requirements on the thickness and uniformity of the coating surface, and the existing electroplating process cannot meet the electroplating needs of superconducting materials

Abstract

The invention relates to a nickel plating process for superconducting materials, which comprises three steps of surface treatment before nickel plating, nickel plating and post treatment. In the nickel plating step, superconducting lines which are washed with water to be neutral in the surface treatment before nickel plating are placed into a pre-plating groove filled with 200 to 240g / L NiCl2 and 60 to 100ml / L HCl, pre-plated with nickel under 30 to 40 EDG C for 30 to 60 seconds, and then washed with water; the washed superconducting lines are placed in a nickel groove filled with 8 to 12g / L NiCl2, 45 to 55g / L boric acid, 500 to 600ml / L bodying agents, 1.0 to 2.0ml / L wetting agents and 1.5 to 2.5ml / L additives and then plated with nickel in the nickel groove under 55 to 65 DEG C for 30 to 60 seconds; and then the post treatment is carried out. The superconducting lines plated by the process has the advantages that the thickness and evenness of the surface of plating layers can meet all index requirements, the conductivity of materials is stable, and the assembling performance is stable.
