摘要： A predicted corrosion amount of a painted or unpainted atmospheric corrosion resistant steel is calculated by using extrinsic corrosion information including weather observation data, an amount of airborne salt, and an amount of sulfur oxide in a planned location for use where the atmospheric corrosion resistant steel is to be used, and intrinsic corrosion information on components of the atmospheric corrosion resistant steel. The weather observation data on this occasion preferably includes the annual wetness time, annual mean wind speed, and annual mean temperature. Moreover, it is preferable to calculate a corrosivity index, estimate a first-year corrosion amount of the atmospheric corrosion resistant steel and a rust stabilization index from the corrosivity index, and calculate a corrosion amount accumulated over time.

摘要： A corrosion detecting probe is to be used in combination with a known electrochemical measuring apparatus for inspecting corrosion state of a steel material buried in a concrete structure. The probe comprises a container made of an electrically insulating material and having an open end adapted to be placed in close contact with a surface of the concrete structure, a cover closing the open end and made of a porous and liquid permeable material, an electrolyte liquid solution filling the container so that the cover is sufficiently impregnated with the solution, and an electrode assembly mounted within the container so as to be immersed at least partially in the electrolyte solution. The electrode assembly includes an elongated reference electrode having a free end portion at least partially immersed in the electrolyte solution, a counter electrode having an electrode plate of a symmetrical configuration with respect to the free end portion of the reference electrode and distanced therefrom, and a current flow line control electrode having an electrode plate of a symmetrical configuration with respect to the free end portion of the reference electrode and disposed in a same plane as the electrode plate of the counter electrode at a distance therefrom.

摘要： A method of detecting the rate of corrosion of an existing steel structure installed in a corrosive environment is disclosed. The method includes treating a measurement surface of the member so that an AC impedance of the measurement surface, when electrochemically measured at a predetermined high frequency range of potential variation applied to the measured surface, takes a first valve within a predetermined range; and second value of the impedance is then electrochemically measured at a low frequency range of potential variation applied thereto. The difference between the first and second values is calculated to detect the corrosion-reaction resistance of the surface and the rate of corrosion is determined on the basis of the detected corrosion-reaction resistance and according to a pre-calculated relation between the rate of corrosion and the corrosion-reaction resistance.

摘要： A sensor for electrochemical measurement is disclosed which includes a chamber made of an electrically insulative material and having an open end portion, a super absorbent polymer material filled in the chamber and absorbing at a selected rate a liquid electrolyte, an electrode disposed in the chamber, and a screen which covers the open end portion of the chamber and which prevents the super absorbent polymer material from dropping out from the chamber but permits the liquid electrolyte to transmit through the screen. A method is also disclosed which uses the sensor to measure the degree of degradation of a coating film on metal or the corrosion protective properties of a rust film created on the surface of steel.
