| 摘要 |
The invention relates to a tin coating (5) with a substantially equiaxial grain structure, a contact element with such a tin coating (5) and a method for applying such a tin coating (5). According to the invention, the tin coating (5) comprises at least two sequentially applied layers containing tin (Sn1, Sn2, Sn3), which are separated from each other by an interlayer (ZW1, ZW2), wherein the interlayer (ZW1, ZW2) generates laterally running grain boundaries (10.2) in the adjoining tin-containing layers (Sn1, Sn2, Sn3). |
