An Investigation of Stress-Corrosion Failures in Titanium Compressor Components


The cracking of J93 jet engine components manufactured from Ti-7Al-4Mo and Ti-5Al-2.5Sn was shown to result from silver chloride stress corrosion. Laboratory testing was conducted to demonstrate the effect of intimate contact between titanium alloys and silver and silver chloride. An investigation of the mechanism of attack suggested that the deleterious effects noted were the result of silver's unique ability to react with, and thereby concentrate minute amounts of chlorine such as might prevail in a test environment. Because of this behavior, silver plate was removed from all areas in the J93 engine where it came in intimate contact with titanium components.
