Abstract

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°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 1W50wt% (especially, 10W40wt%) 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.
