How many people know what galvanic corrosion means?
- Avshalom 3y agoevery one who has ever owned an aluminum boat, or generally worked with aluminum that's anywhere near electricity. https://en.wikipedia.org/wiki/Galvanic_anode https://en.wikipedia.org/wiki/Galvanic_anode It's not an obscure thing; field specific maybe, but it's very much sub-table-stakes.
- andyjohnson0 3y agoMost people who've done secondary school chemistry would know what that is. Uses technicals terms != is engineer.
- quickthrowman 3y agoEvery single electrician I know is familiar with galvanic corrosion as well as how to mitigate it with insulation, dielectric grease, sacrificial anodes, etc. Steel and aluminum are the two most common metals that we use to make things. Galvanized steel has a zinc coating that acts as a sacrificial anode, almost any steel that is installed outside that isn’t stainless is galvanized.
- armadsen 3y agoI am an engineer, though not at all involved in materials science/engineering, and I've known what galvanic corrosion is since I was a teenager. It's not exactly an obscure phenomenon.
- meepmorp 3y agoWe covered that in high school chemistry, along with an in-class demo and a section in the book on sacrificial anodes and how they're used to prevent corrosion in things like oil pipelines. It was a US public school.
