<P>PROBLEM TO BE SOLVED: To provide a method for further readily determining a state of passivation film, without requiring configuration of an electrochemical equivalent circuit of a metal corrosion system. <P>SOLUTION: In a step S101, gas is supplied from one side of a metal structure. For example, the metal structure is a steel plate and the supplied gas is hydrogen. In a successive step S102, an amount of the gas passing through the metal structure is measured. For example, an amount of the supplied gas passing through the steel plate is measured. The measurement of the passing gas is performed, for example, by bringing a surface on the other side of the metal structure into contact with an electrolyte and detecting a current amount flowing between an electrode disposed in the electrolyte and the surface of the metal structure in contact with the electrolyte. <P>COPYRIGHT: (C)2012,JPO&INPIT |
