Abstract
PURPOSE: To obtain a cathode for electroysis specified by low hydrogen overvoltage and high durability and corrosion resistance by forming the 2nd coating layer of Ni contg. A or having porous surfaces via the alkali resistant 1st coating layer on a base material consisting essentilally of iron.
CONSTITUTION: The 1st coating layer which consists of metals such as Ni, Co, Mo, W or the like or their alloys, has good adhesiveness to a base material and has alkali resistance and electric conductivity is formed on a base material consisting of iron or an alloy contg. iron as an essential component, by electroplating or the like, and further several μWseveral hundreds μ ruggedness is provided by blasting on the surface thereof. It is also possible to form the 1st coating layer having ruggedness by a melt-spraying method. Thence, Ni plating contg. S is applied on the 1st coating layer or Ni alloy plating is applied thereon by using an Ni plating bath contg. sacrificing metal such as Zn, thence the sacrificing metal is removed with an alkali bath to make the plated surface porous, whereby the 2nd coating layer is formed.
