Diamond coated cutting tools have been around for some time. But the coating is known as polycrystalline, and it is composed of small diamond crystals fused to a cutting tool surface.
A new technology that uses CVD (chemical vapor deposition) to develop a homogeneous diamond layer on cutting tools has been announced by Norton Company, 1 New Bond St., Worcester, MA 01606. They are working in conjunction with Sandvik Coromant of Fairlawn, New Jersey, to coat a variety of cutting tools and indexable inserts.
The CVD process uses a plasma of hydrogen in methane gas under carefully controlled conditions to generate a diamond deposition. Norton ...
