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.
Using a 3D printer, CNC router, and existing powertrain components, a team of engineers is building an electric car from scratch on the floor of the International Manufacturing Technology Show in Chicago this week.
In November, a European space probe will try to land on the surface of a comet moving at about 84,000 mph and rotating with a period of 12.7 hours. Many factors make positioning the probe for the landing an engineering challenge.
NinjaFlex flexible 3D printing filament made from thermoplastic elastomers is available in a growing assortment of colors, most recently gold and silver. It's flexible and harder than you'd expect: around 85A (Shore A).
