METHOD OF CALCULATING SEA SALT-EQUIVALENT DEPOSITION AMOUNT USING ACM-TYPE CORROSION SENSOR

摘要

PROBLEM TO BE SOLVED: To provide a method of enhancing accuracy in measurement of sea salt-equivalent deposition amount on an electrode surface of an ACM-type corrosion sensor by producing a calibration curve from the amount of salt spontaneously deposited on a surface of the ACM-type corrosion sensor and corrosion current output of the sensor with consideration for environmental factors.;SOLUTION: A calibration curve for calculating a sea salt-equivalent deposition amount in the atmosphere is produced from a relationship between humidity and electric current output of an ACM-type corrosion sensor that has been exposed to a measurement environment for a period of 10 to 40 days and the amount of spontaneously deposited sodium chloride per unit area of a sensor surface.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
