Thanks Ken, I have seen tables like this before, and this one is nice by virtue of its publishing date. I wonder where they obtained their information, is it possible that in the past it was considered "common knowledge"? Most tables like this I've seen tend to only cover elemental metals. Personally, I find that correlating two different alloyed metals to a list like this is very hard.
In the end, I suppose what I really want is a way to understand the potential for corrosion between any two metals and ultimately what is the likelihood of a product operating correctly for its entire life. This is probably the reason we still do salt fog testing in the real world. -Doug Douglas E Powell Laporte, Colorado USA doug...@gmail.com http://www.linkedin.com/in/dougp01 On Mon, Feb 8, 2021 at 9:21 AM Ken Javor <ken.ja...@emccompliance.com> wrote: > From the Reference Handbook for Radio Engineers, 2nd edition, 1946: > > > > > > Ken Javor > Phone: (256) 650-5261 > > > From: John Barnes <jrbar...@iglou.com> > > Reply-To: John Barnes <jrbar...@iglou.com> > > Date: Mon, 8 Feb 2021 10:43:29 -0500 > > To: <EMC-PSTC@LISTSERV.IEEE.ORG> > > Subject: Re: [PSES] AW: [PSES] Friday Question - table of > electrochemical > > potentials > > > > Dürrer, > > The table in the Wikipedia article > > https://en.wikipedia.org/wiki/Galvanic_corrosion#Anodic_index > > has more entries, is more descriptive, and doesn't totally agree with > > Table 7-1 on page 156 of Gershon J.
