摘要： [Object]
To provide a surface treated steel foil that is for a current collector and that has hydrogen barrier properties suitable for a battery using a hydrogen occluding alloy.
[Solving Means]
The surface treated steel foil for a current collector has a first surface on which a hydrogen occluding alloy is disposed and a second surface located on a side opposite to the first surface. The surface treated steel foil for a current collector is characterized by having an iron-nickel alloy layer that is laminated on at least one surface side of the first surface side and the second surface side on the side opposite to the first surface side of a metallic base material composed of steel foil and that restrains permeation or diffusion of hydrogen in the surface treated steel foil for a current collector, and is characterized in that at least one layer included in the iron-nickel alloy layer has a thickness of not less than 0.5 um.-

摘要： The present application relates to a sterilizing and environment-friendly composite plating layer, a preparation method thereof and a sterilizing and environment-friendly product. The sterilizing and environment-friendly composite plating layer includes: a semi-bright nickel layer, a high-sulfur nickel layer and an environment-friendly white chromium composite sterilizing layer; the semi-bright nickel layer is adapted to be positioned on a substrate having a sterilizing requirement; the high-sulfur nickel layer is disposed on the surface of a side of the semi-bright nickel layer away from the substrate; the environment-friendly white chromium composite sterilizing layer is disposed on the surface of a side of the high-sulfur nickel layer away from the substrate; the environment-friendly white chromium composite sterilizing layer has a nano-needle structure and is formed by a composite raw material containing sterilizing ammonium salt, and the concentration of the sterilizing ammonium salt in the composite raw material is 50-100 g/L. The sterilizing and environment-friendly composite plating layer and the sterilizing and environment-friendly product of the present application can be prepared directly by an electroplating method, and can have good broad-spectrum sterilizing effect without spraying antibacterial materials containing nano Ag + , Cu 2+ , and the sterilizing effect can be directly displayed.

摘要： Providing an anti-corrosion terminal material having high corrosion resistance effect and good adhesiveness of a film.
A first film is formed on at least a part of a base material in which at least a surface is made of copper or copper alloy; in the first film, a zinc layer made of zinc or zinc alloy is formed on a mixed layer in which a copper-tin alloy region made of copper tin alloy and a tin region made of tin or tin alloy other than copper tin alloy are mixed; the zinc layer is in contact with both the copper-tin alloy region and the tin region of the mixed layer; a ratio R1/R2 is 0.05 or more and 2.5 or less where a length in contact with the copper-tin alloy region in a cross section along a thickness direction is R1 (µm) and a length in contact with the tin layer is R2 (µm).-
