  • Publication number: 20210010926
    Abstract: The method for a corrosion resistance test of a coated metal material is an electrochemical method simulating corrosion proceeded by damaged portions in the surface treatment film 4. Two artificially damaged portions 5 spaced from each other in a coated metal material 1 that is obtained by providing a surface treatment film 4 on a metal base 2 are electrically connected to each other by an external circuit 11 via an aqueous electrolyte material 6, and corrosion proceeds by supplying current using one of the artificially damaged portions 5 as an anode site and the other as a cathode site.

  • Publication number: 20200386667
    Abstract: A physical property evaluation method is the method for evaluating physical properties of a film-shaped measurement target object by means of an electrochemical method, the method including the step of causing an electrolytic solution to contact a front surface of the measurement target object. The speed of penetration of the electrolytic solution into the measurement target object is adjusted in such a manner that the levels of the front-side temperature and the back-side temperature of the measurement target object and a difference between the front-side temperature and the back-side temperature of the measurement target object are adjusted.

  • Publication number: 20200182824
    Abstract: Disclosed herein is a method of testing a corrosion resistance of a coated metal material including a surface treatment film on a metal substrate. The method includes: treatment of interposing a water-containing electrolyte material containing water, a supporting electrolyte, and a water penetration enhancer, between a surface of the surface treatment film of the coated metal material and an electrode; holding of the water-containing electrolyte material on the surface of the surface treatment film for one minute to one day; and electrical conduction from the electrode through the water-containing electrolyte material to the coated metal material.

  • Publication number: 20190353581
    Abstract: Disclosed is a humidity sensor for evaluating the degree of corrosiveness of an environment under a coating. The humidity sensor includes a sensor body including a first conductive material and a second conductive material which are alternately stacked with an insulating material interposed therebetween. The sensor body has an outcrop in which layers of the first and second conductive materials are alternately exposed with a layer of the insulating material interposed therebetween, the outcrop serving as a sensor surface. A voltage is applied between the first and second conductive materials, so that humidity is detected based on a current which flows when a short circuit is caused between the first and second conductive materials by humidity on the sensor surface.

  • Publication number: 20190353580
    Abstract: A humidity sensor for evaluating the degree of corrosiveness of an environment under a coating has a sensor body including a first metal material and a second metal material which have different standard electrode potentials and which are alternately stacked with an insulating material interposed therebetween. The sensor body has an outcrop in which layers of the first and second metal materials are alternately exposed with a layer of the insulating material interposed therebetween, the outcrop serving as a sensor surface. Humidity is detected based on a corrosion current which flows when a short circuit is caused between the first and second metal materials by humidity on the sensor surface.
