Improving Metal Cutting With Organic Monolayers

How can you improve the cutting of “gummy” metals? Purdue University engineers have found that a one molecule layer of the right materials is enough to make a machinist's job easier.

The researchers previously showed that the application of a permanent marker or Sharpie, glue or adhesive film made it easier to cut metals such as aluminum, stainless steels, nickel, copper and tantalum for industrial applications. Now they've learned that using an organic monolayer of these materials causes metals to be locally embrittled resulting in improved machining.
