Title: Method of detecting degree of deterioration of coating on coated metal member
Inventor: HIRAYAMA RYUTA
IPC: G01N17/02
Filed: 1990-07-18
Abstract: PURPOSE:To precisely detect a degree of deterioration over a wide range by adding an auxiliary capacitance component in parallel between an electrode making contact with an electrolyte and a painted metal member in a condition in which the electrolyte is made into contact with the outer surface of a coating, and by applying an a.c. voltage having a frequency which is changed, in order to measure a variation in the frequency of an electrochemical impedance. CONSTITUTION:An auxiliary capacitance component 17 is added in parallel between an electrode 5 making contact with an electrolyte 4 and a painted metal member 1 having an outer surface applied thereover with a coating 3 which is made into contact with the electrolyte 4, and an a.c. voltage having a frequency which is changed at predetermined intervals is applied therebetween. By measuring a variation in the frequency of the electrochemical impedance of the member 1 due to the application of the a.c. voltage, the area of a peel-off part of the coating 3 is quantitatively detected by a detecting means 16 in order to detect a degree of deterioration. Since the cross- over frequency can be shifted to the lower side by the auxiliary capacitance component even if the cross-over frequency shows its high value due to progression of the degree of deterioration, it is possible to precisely evaluate the coating 3 in which the degree of deterioration is developed over a wide range.
