Title: Ni-plated steel sheet, formed part made of same ni-plated steel sheet, and their production
Inventor: SUGIKAWA HIROFUMI
IPC: C25D5/26
Filed: 1990-05-15
Abstract: PURPOSE:To improve corrosion resistance, workability, and mirror-finish characteristics by applying Ni plating to the surface of a steel basis material, forming an Fe-Ni diffusion layer of uniform and prescribed thickness by means of annealing treatment, and then applying Ni plating to the surface of the above layer. CONSTITUTION:Ni plating is applied at least to one surface between the surface and the rear surface of a steel basis material to a small thickness. It is preferable to regulate the coating weight of the above Ni plating to 1.5-9.0g/m<2>. Subsequently, the resulting plated steel sheet is heated to 500-900 deg.C for 0.5min-36hr in a neutral or reducing gas atmosphere of N2, N2+H2, etc., to undergo annealing treatment. By the above procedure, the above Ni plating is completely formed into an Fe-Ni diffusion layer and, as a result, the Fe-Ni diffusion layer having a uniform and prescribed thickness of 1.0-8.0mu is formed on the surface of the steel basis material. Then, Ni plating is applied to the above layer, by which the steel basis material, the Fe-Ni diffusion layer, and the Ni plating layer are laminated via linear interfaces, respectively. By this method, the adhesive strength of the Ni plating layer can be improved by means of the above Fe-Ni diffusion layer, and an Ni-plated steel sheet excellent in corrosion resistance, workability, and mirror-finish characteristics can be obtained.
