Abstract
Purpose
This study aims to provide a model to predict the service life of a thick organic coating.
Design/methodology/approach
A series of thin coating films are rapidly tested under the same exposure condition as the thick coating in its service condition by means of electrochemical impedance spectroscopy, scanning electron microscopy, energy dispersive spectroscopy and X-ray diffraction.
Findings
The validity of the model is successfully verified. The long-term protectiveness or service life of a thick organic coating can be rapidly predicted.
Originality/value
The prediction model does not require long-term experiments or any test that may alter the degradation mechanism of the thick coating.
