Is matching metals to avoid galvanic corrosion a lost cause?

I just use a little corrosion inhibitor here.
What do you use?
It sounds counter-intuitive, but I think contact lubricants might be a good idea.
I did some research into this a few years ago while working for an avionics company. The US Air Force had continual reliability problems with fighter jet electronics wiring, and commissioned a lot of internal and university research, with some surprising results. Although some materials are unsuitable, they found that good contact lubricants made a dramatic improvement in contact impedance degradation over time, largely because they kept oxygen and water away from the contact surfaces. There were also improvements in assembly and reducing fretting. You can't use any old lubricant as it needs to be chemically inert. IIRC silicone greases were effective. There was one particular product that came to the fore. There was a Mil-STD for it, and it became the go-to solution for everything, and was also a very good corrosion inhibitor. I'll try to find the name. I believe modern cars use contact lubricants for switches and connectors as a matter of course now.

Edit: It was called Super CORR A.

I have always used silicone lube on vacuum tube pins to great effect. You get people who claim it degrades the connections, but you also get people who claim the earth is flat.

It doesn’t interfere with the contact points in the connection. If it does, then it's a poorly designed connector and should be replaced right away!

When used in electrical connections, the grease will be displaced at the contact points, effectively serving as an insulator and moisture barrier.

Indeed. Also makes them 100x easier to remove and replace.
 
What?
