This study examines the role of short-term changes in the coating-substrate interface as a means to predict the long-term coating performance. A through-coating defect is introduced and interfacial changes are quantified using EIS testing over short times of exposure to aqueous environments. The ability of these short-term measurements to predict long-term performance was examined through a blind comaprison to 300h h salt spray results using 44 coating systems. EIS data acquired after the introduction of the defect was essential and the dominate factor in the prediction of 3000 h salt spray results. The high correlation of short-term to long-term results show the important role of interfacial stability and demonstrate a quantitative method to rapidly predict long-term coating performance for these materials. |
