Trivalent Chromate Treatment
Trivalent Chromate Treatment
(OP)
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?





RE: Trivalent Chromate Treatment
The purpose of the application (corrosion protection, base for paint etc.) is not explained.
The process operating conditions and the thickness of the coating are not clarified.
The requirements after exposure to cold temperature are not established.
It seems that more information would be helpful.
