METHOD FOR MEASURING PLATING THICKNESS OF PLATING MATERIAL, METHOD FOR MEASURING AMOUNT OF CORROSION OF PLATING MATERIAL, AND CORROSION SENSOR OF PLATING MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a method for measuring the plating thickness of a plating material in which a conductive plating layer is formed on a conductive base material precisely nondestructively.;SOLUTION: A method for measuring the plating thickness of a plating material includes the steps of: measuring impedance of a plating material having a base material and a plating layer using an AC power supply of a frequency within the range of a frequency greater than the frequency at which a skin effect appears in the base material and a frequency less than the frequency at which a skin effect appears in the plating layer, and calculating the plating thickness of the plating material based on the resistance of the impedance.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2017,JPO&INPIT
