Cutting fluids used during the machining process are expensive,can be toxic, and produce a significant waste stream. NanoMech,Inc., developed a patented, innovative nanostructured coating for cutting tools based on the principles of biomimicry. The TuffTek® coating contains the hard phase deposited in a nodular structure similar to a lotus leaf’s surface, and the soft phases in the micro-reservoirs surrounded by the nodules, keeping the contact surface refreshed with lubricants.  The TuffTek® coating can improve tool life by 300 percent or more in certain applications. The technology was called “coating’s holy grail” by Cutting Tool Engineering (October 2008). NanoMech has successfully marketed TuffTek® coatings to cutting tool manufacturers and users in the automotive and other manufacturing industries, but its coating technology has applications in numerous markets, including manufacturing, biomedical, electronics, and military. The company has received several awards for its innovative products and processes, including Frost & Sullivan’s 2005 Award for Excellence in Technology in the field of Advanced Coatings, Surface Technologies, and Spray Coatings; the R&D Magazine Micro/Nano 25 Technologies of Tomorrow Award naming NanoMech’s cBN coatings among the 25 best micro- and nanotechnologies of 2006; and a Recognition of Excellence in Innovation Award from the U.S. Under Secretary of Commerce for Technology in 2007.
