TuffTek® is a nano-engineered surface technology product platform with combinatorial chemistry. It includes nanocomposite coatings (cubic boron nitride-based), nanostructured multiple-layered coatings, and a family of unique thin coatings.

The nanocomposite and nanostructured multiple-layered coatings are typically deposited at relatively high temperatures and mainly applied to carbide and certain ceramic substrates. The uniquely configured thin coatings are typically deposited at a relatively low temperature and can be deposited on a variety of substrates or components, including carbides and most steels.

TuffTek® surface engineering offers high hardness and toughness, thermal resistance, and a low coefficient of friction, depending on the application. It has been widely used for machining materials, from steels, irons, and heat-resistant alloys to woods. TuffTek® helps extend tool or component service life, reduce machine downtime, and improve productivity.
