Plattiertes Element und Verfahren zum Herstellen desselben

摘要

According to the present invention, in order to suppress whisker formation on a plated member having a plated layer comprising a lead-free material, the orientation index of the plane (321) in a plated layer for a plated member 3 having a plated layer 2 comprising a lead-free material on the surface of a base material 1 is 2.5 to 4.0. In another embodiment, the value (220)/(321) derived from the ratio of the orientation index of the plane (220) to that of the plane (321) for the plated layer is 0.5 to 1.5. An undercoat layer 4 having the orientation plane (220) may be formed between the base material 1 and the plated layer 2.
