Abstract: A process for physical vapor deposition of a refractory coating such as titanium nitride on a nonconductive substrate such as a ceramic substrate and the coated substrate produced thereby. The nonconductive substrate is coated by cleaning the nonconductive substrate surfaces and then depositing a first layer of a refractory metal such as titanium metal on the nonconductive substrate by physical vapor deposition. A second layer of a refractory compound such as titanium nitride is then deposited on the first layer by physical vapor deposition to produce a coated nonconductive substrate having enhanced coating adhesion.

Abstract: A cutting tool is provided composed of a hard substrate having a PVD coating thereon having three layers. The innermost of first layer (1) is composed of a group IVB (titanium, hafnium or zirconium) metal alloy. The middle or second layer (2 and 3) is composed of a group IVB carbonitride. The outermost or third layer (4) is also composed of a group IVB metal nitride. The PVD coating is characterized by high hardness and high residual compressive stresses.
