Abstract
Official abstract text for this publication.
In a terminal material with a silver coating film including a silver layer on a surface, a terminal and a terminal material having high reliability are easily manufactured with low cost without a heat treatment. A base material formed of copper or a copper alloy; and nickel layer, an intermediate layer, and a silver layer laminated on the base material in this order are included, the nickel layer has a thickness of 0.05 μm to 5.00 μm and is formed of nickel or a nickel alloy, the intermediate layer has a thickness of 0.02 μm to 1.00 μm and is an alloy layer containing silver (Ag) and a substance X, and the substance X includes one or more kinds of tin, bismuth, gallium, indium, and germanium.
First claim
Opening claim text (preview).
The invention claimed is: 1. A terminal material with a silver coating film, comprising: a base material formed of copper or a copper alloy; and a nickel layer, an intermediate layer, and a silver layer laminated on the base material in this order, wherein the nickel layer has a thickness of 0.05 μm to 5.00 μm and is formed of nickel or a nickel alloy, the intermediate layer has a thickness of 0.02 μm to 1.00 μm and is an alloy layer containing silver and a substance X, and the substance X is selected from any one or more of gallium and germanium. 2. The terminal material with a silver coating film according to claim 1 , wherein the intermediate layer has a two-layer structure of a first layer containing the substance X as a main component and a second layer containing silver as a main component. 3. The terminal material with a silver coating film according to claim 1 , wherein the nickel layer contains any one or more of phosphorus, boron, tungsten, sulfur, zinc, and tin in a total content of 1 at % to 40 at %. 4. The terminal material with a silver coating film according to claim 3 , wherein the nickel layer has a structure containing an amorphous material. 5. A terminal with a silver coating film formed of the terminal material with a silver coating film according to claim 1 . 6. The terminal material with a silver coating film according to claim 2 , wherein the nickel layer contains any one or more of phosphorus, boron, tungsten, sulfur, zinc, and tin in a total content of 1 at % to 40 at %. 7. The terminal material with a silver coating film according to claim 6 , wherein the nickel layer has a structure containing an amorphous material. 8. A terminal with a silver coating film formed of the terminal material with a silver coating film according to claim 2 . 9. A terminal with a silver coating film formed of the terminal material with a silver coating film according to claim 3 . 10. A terminal with a silver coating film formed of the terminal material with a silver coating film according to claim 4 . 11. A terminal with a silver coating film formed of the terminal material with a silver coating film according to claim 6 . 12. A terminal with a silver coating film formed of the terminal material with a silver coating film according to claim 7 .
