Re-finishing Chrome Parts

December 23, 2008

We have chrome plated wire fan grills (you see them on PC power supplies). We ran these though a salt fog test, and they failed. We need these to meet MIL-DTL-5541 [on DLA]. Is it straight forward to get these refinished? I'm concerned since they are already plated.

Thanks in Advance.

Hi, Pat. Mil-DTL-5541 refers to chromate conversion coating of aluminum components. "Chrome Plated" would usually refer to that mirror like plating you would see on a classic car bumper.

It should not be a big deal to get the parts recoated, but some alloys will perform very poorly in a salt fog test. Do you know what alloy they are?

Regards,
