I am a mechanical design engineer conducting a thorough investigation of whether NavAir trivalent chromate pre-treatment/post-treatment meets the requirements for a military application. I have found a bunch of great test data, but nothing that tells me that the treatment meets the requirements after exposure to extremely cold temperature (-125 F). They tested this treatment on aircraft, and aircraft see similar temperatures, but I can't find anything that confirms that low temperature exposure isn't a problem. I imagine that its fine, but guessing is not an option, and at this point in the design process I can't do all of the testing that would be required. Is there any resource, ie. literature, that will help me understand from a materials engineering point of view that I should not have a concern for this?
