Corrosion Protection of Al Alloys for Aircraft by Coatings With Advanced Properties and Enhanced Performance

摘要

The report presents research that addresses research performed at NDSU for environmentally compliant corrosion protection in coatings systems of greatly extended lifetimes for present and future aircraft. For present coatings system, this work included modeling degradation in the bulk of a coating by the Monte Carlo methods developed in this laboratory for coating surface degradation, to test its applicability to the prediction of the lifetime of corrosion protection in coatings. Also work was performed to improve the analysis of the dielectric properties of organic coatings by the use of EIS, focusing on the higher frequency parts of the EIS spectrum dominated by these properties.
