Part of a core foundation

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.

great article. Gave me lots of material to think about. Very clear with nice example.

Thanks. Really enjoyed reading.

 

Totally brought me back to chem101 or 102, who remembers now !!!

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.

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 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.

Good article -- and surprising, Dave. The chemistry here is counter intuitive. there are some things that take knowledge, not just instinct.

Welcome, Dave, as Design News' newest guest blogger. For readers who enjoyed this -- as did I -- we'll have another blog from Dave in a few weeks. As you can tell, he's a serious materials expert.

Seems like a subject that ought to covered in more depth.  Easy for a bridge designer for instance to build a time bomb into a bridge without intending to.  Important for field engineers to make clear to maintainers why certain hardware is used to eliminate entirely avoidable failures.  Really glad he brought the subject up.

Interesting article. I would also like to see a basic tutorial of how to prevent galvanic corrosion actively with electric current. What are the rules of thumb for current flow or voltage, magnitude/polarity, critical control parameters, reliable connection, etc?  I know such devices exist but not much about them. This information might be useful for protection of metallic pipes in the ground, marine fixed and floating structures, expensive industrial and residential plumbing systems, and any metal structure with dissimilar metals and/or ground/electrolyte contact.  Would this method be any better than the common "sacrificial anode" method in saltwater?

Thanks a lot for this great article on understandind galvanic corrosion. This is a very important topic in the ever increasing "mechatronics" design and development enviornment. These types of articles are worth their value in gold. This is a must read article.

As additive manufacturing (including 3D printing) becomes increasingly popular among businesses as a quick and easy solution to creating and evaluating prototypes and end-use products, the debate about whether to outsource production or to purchase equipment for in-house use is at the forefront of industry discussions.
With increasing terrorist threats overseas, organizations are thinking about how best to defend themselves here and abroad. Engineering can play a role, especially when it comes to putting a barrier between yourself and the bad guys.
Time to market is everything, but at the same time, you cant sacrifice quality for speed. Thats where additive manufacturing comes into play.
In the last few years, use of CFD in building design has increased manifolds. Computational fluid dynamics is effective in analyzing the flow and thermal properties of air within spaces. It can be used in buildings to find the best measures for comfortable temperature at low energy use.
Feature-advantage-benefit could help engineers in how we approach design problems, how we sell our ideas to management, and how we market ourselves when it comes to jobs.
