Galvanic corrosion testing standard!
Galvanic corrosion testing standard!
(OP)
Hi,
I would like to know if there are any mil standards for testing galvanic corrosion between dissimilar metals. I was going to try salt spray and thought if I could validate the testing to mil spec it would be good.
Thanks,
V.

There is no spec that I am aware of that deals with a galvanic couple or dissimilar metal crevice corrosion.

I did find Mil-std-889B but not very useful.

1. Humid Stage—50 °C and 100% humidity, 6 h in duration,
2. Salt Application Stage—15 min duration conducted at ambient conditions
3. Dry Stage—60 °C and 50% RH, 17 h and 45 min in duration
This sequence is then repeated for a number of cycles, typically between 60 and 80, to simulate years of automotive exposure.
