A Study of Transport Processes and Initiation of Corrosion Under Paint Films.

Abstract

Combating corrosion of airplane structure is a large and increasing cost to the Air Force. Fundamental knowledge of how protective coatings function is required in order to develop improved coating systems. This research was directed to obtain quantitative knowledge of mass transport and kinetic mechanisms that result in initiation of corrosion under paint films. Mathematical modeling of transport processes and electrochemical tests on paint films were conducted concurrently. Coating systems of current use in the Air Force, polyurethane and epoxy, were examined. Experiments were conducted with detached films and with films on aircraft alloy aluminum and iron substrates.
