Title:
CYCLIC FLEXING SALT-SPRAY CHAMBER AND METHODS
Document Type and Number:
Japanese Patent JP2019144274
Kind Code:
A
Abstract:
To provide methods and apparatus for determining operational environment-specific performance, lifetime assessment, and failure mode investigation of material systems.SOLUTION: Aspects described herein generally relate to apparatus and methods for determining operational performance of material systems. Apparatus generally comprise a salt fog chamber having a fixture support having material system flexing components to test corrosion of an aircraft material system. In one aspect, a material performance chamber comprises a salt fog chamber and a jaw configured to flex a material system. Methods for determining corrosion include exposing a material system such as a panel to a salt fog, and flexing the material system at a prescribed frequency. In one aspect, a method for determining corrosion includes exposing a material system to a salt fog. The pH of the salt fog is from about 3.0 to about 9.0, and the material system is flexed at a frequency from about 0.1 Hz to about 60 Hz.SELECTED DRAWING: None
