  • PLUG-IN CONNECTOR
    Publication number: 20180269603
    Abstract: A plug-in connector has a press-in body which is coated with a first Ni-containing layer and a second Ni-containing layer. The first and/or the second Ni-containing layer is a nanocrystalline or amorphous layer. The first Ni-containing layer and the second Ni-containing layer have grain sizes of different orders of magnitude. In particular, one of the layers can be microcrystalline and the other can be nanocrystalline or amorphous.
