AIR CORROSION ENVIRONMENT MEASURING DEVICE AND AIR CORROSION ENVIRONMENT MEASURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide an air corrosion environment measuring device and an air corrosion environment measuring method capable of measuring the corrosion severity of air circumstance without changing measuring device depending on a range of the severity.;SOLUTION: An air corrosion environment measuring device 100 includes: a metal base plate 2 having a principal plane 3; and a metal film 1 of a metal which is in contact with the principal plane 3 the ionization tendency of which is larger than the ionization tendency of the metal of the metal substrate 2. The film thickness of the metal film 1 in a vertical direction with respect to the principal plane 3 changes smoothly in one or more directions parallel to the principal plane 3.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
