Accelerated Corrosion Testing

Abstract

Available methods for accelerated testing of corrosion behavior yield results which are not sufficiently accurate or reliable for predicting the service life of aircraft components and materials which degrade or fail due to environmental attack. Research has been conducted in controlled atmospheres on the localized environmental enhancement of crack-growth rates of aerospace alloys in order to provide the basis for development of realistic accelerated corrosion tests. Slow-strain-rate, corrosion-fatigue, and rising-load experiments have been conducted on high-strength 4340 steel and 7075-T6 aluminum alloy using accelerating pollutants such as sulfur dioxide, nitrogen dioxide, surface salt, and ambient to 100%-relative-humidity (RH) air in a specially designed atmospheric chamber.
