Novel Environment-Assisted Cracking Test for Aerospace Materials and Coatings Characterization

Abstract

The Static Load Environmentally Assisted Cracking (SLEAC [trademark]) system and test method are being developed to characterize the capacity of coatings to protect structural alloys from environment assisted cracking (EAC) or stress corrosion cracking (SCC). Previous research by Luna Labs demonstrated that an instrumented load frame could be used to continuously measure cracking in situ during atmospheric corrosion tests. The purpose of this project was to advance the technology, refine the test method, and deliver a low rate initial production SLEAC system for evaluation at NAWCAD.
