摘要： PURPOSE:To provide the titled electrode material having an extremely high electrochemical catalytic activity together with a high corrosion resistance, which consists of the amorphous alloy containing P and/or Si Ir and/or Ru in predetermined ratios, the balance consisting of at least one element selected from the group consisting of Pd, Rh and Pt. CONSTITUTION:The titled electrode material consists of the alloy containing 10-40at.% of P and/or Si and 20-80at.% of Ir and/or Ru, the balance substantially consisting of not less than 10at.% of at least one element selected from the group consisting of Pd, Rh and Pt. To produce the above-mentioned electrode material, a raw material 4 having the above composition is fed through a feeding inlet 1 together with an inert gas for preventing the oxidation of the material, and is introduced into a heating furnace 5 through a nozzle 3 of a quartz pipe 2, where it is melted by heating. The molten material is then injected by a compressed inert gas onto the outside peripheral surface of a roll 7 which is rotating at a high speed of 1,000-10,000r.p.m., thereby obtaining the objective electrode material in the form of an elongaged thin plate. Said amorphous alloy has excellent mechanical properties such as a Vickers hardness of about 400-600, a tensile strength of about 120-200kg/mm. , and the like.

摘要： PURPOSE:To activate remarkably an amorphous metal surface, by diffusing and infiltrating zinc into the amorphous metal surface, and leaching selectively the infiltrated zinc with an alkaline solution or acid solution. CONSTITUTION:Zinc dust and an amorphous metal including one or more metals selected from metals of Group IVa, Va, VII andIb of the Periodic Table of the Elements are heated at a temperature range between 200 deg.C and the crystallization temperature of the amorphous metal so that the zinc is infiltrated into the surface of the amorphous metal. Then the amorphous metal is immersed in a 1-50wt% (especially, 10-40wt%) strength alkaline solution or acid solution to leach selectively the infiltrated zinc so that the surface of the amorphous metal is activated. As an alkali use is made of sodium hydroxide, potassium hydroxide and lithium hydroxide, and as an acid use is made of inorganic acid such as sulfuric acid and hydrochloric acid, and organic acids such as formic acid and acetic acid.
