Thanks for a great article on a basic and important subject. I've actually been wondering about galvanic corrosion since I'm coming across the topic here at DN a lot when writing about coatings and adhesives.
I'm with Beth--I've had to learn or re-learn a lot of basic chemistry in this beat, and am astonished that engineers have so little training in it. Aside from basic principles of ME, it's the other main subject I keep running into here.
That's really hard to believe. I would think now with so much (or somewhat, however you want to look at it) of the focus on sustainability and alternative energy, chemistry and the make up of matter would be more important than ever to basic engineering work. Hopefully, we'll start to see a change in engineering curriculum to reflect that.
Thanks, Beth! You're right that this is something that should be part of a basic engineering education. Unfortunately, most mechanical engineering programs only require one semester of chemistry. Most universities which have materials engineering departments offer an upper-level undergraduate course in corrosion as an elective, but it's not usually required.
Great primer, Dave, on a topic that should be top of mind for engineers. I'm actually surprised this kind of material isn't duly covered in the standard engineering curriculum. Seems like materials/chemistry 101, especially for engineers trying to create products that have lasting legs.

In a bid to boost the viability of lithium-based electric car batteries, a team at Lawrence Berkeley National Laboratory has developed a chemistry that could possibly double an EV’s driving range while cutting its battery cost in half.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
