NICKEL ELUTION SUPPRESSION METHOD AND DEVICE FOR WATER SUPPLY WITH NICKEL ELUTION SUPPRESSED
PROBLEM TO BE SOLVED: To provide a method for suppressing elution of nickel into water, especially elution of nickel into tap water and a device for water supply with reduced and suppressed bleeding of nickel.SOLUTION: There is a method for suppressing bleeding of nickel into water contacting with a member, where the member contacting with water is a device for water supply, for example, a cock metal fitting. The surface of the member is provided with plating consisting of an alloy of at least one selected from cobalt, tin, iron and phosphorus and nickel. One of the nickel alloy plating is nickel cobalt alloy plating. By placing the member in an environment contacting with water, it is possible to suppress bleeding of nickel into water contacting with the member.SELECTED DRAWING: None
【課題】水へのニッケル溶出、とりわけ水道水へのニッケルの溶出を抑制する方法およびニッケルの浸出が低減・抑制された水道用器具の提供。【解決手段】水と接触する部材の表面、例えば水道用器具である水栓金具において、コバルト、スズ、鉄およびリンから選択される少なくとも一つと、ニッケルとの合金からなるめっきを設け、そのニッケル合金めっきの一つが、ニッケルコバルト合金めっきであり、部材を水と接触する環境に置くことにより、部材と接触する水へのニッケルの浸出を抑制する方法。【選択図】なし
