cbn coatings on cutting tools

CBN coatings on Cutting Tools

cubic boron nitride films (> 1 µm), the development of a cBN coating on non-silicon substrate materials remains a scientific challenge. Though, only the use of substrate materials other than silicon leads to an application of cBN based coatings on cutting tools. Our approach to obtain thicker cBN films leads to an

What is the World’s Strongest Adhesive?

Polyurethane adhesives, however, generally do not have as high “lap shear strength” as epoxies. This lap shear strength is a measure of an adhesive’s ability to endure the force applied to bonded substrates that get pulled in opposite directions.
