Hi Blair, I suggest you take a good and the cloudy unit and EDX to see if there are any corrosive elements such as Chlorine, Sulphur etc.

Subject: [TN] Chromate coatings
Hi Technetters! Getting ready for the long weekend (at least here in the US)?
I'm looking for some advice on chromate coatings. We produce a phone for mining applications, which uses a battery held in by a bracket. The bracket is chromate coated.
The most recent batch of brackets sent out to the coating house came back with a cloudy appearance to the coating. Apparently something hiccupped in their process. The process can't be repeated, so we either scrap the parts and make new ones, or use them as is. Problem is, I don't know if the cloudy appearance will affect the corrosion protection properties. Any chromate experts out there that can offer any advice on this?
Thanks,
Blair
