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: Procédé concernant la déposition en phase gazeuse par procédé physique d'un revêtement réfractaire comme du nitrure de titane sur un substrat non-conducteur comme un substrat en céramique, et le substrat recouvert ainsi obtenu. Pour appliquer le revêtement sur le substrat non-conducteur, on nettoie tout d'abord les surfaces dudit substrat, puis on procède à la déposition en phase gazeuse par procédé physique d'une première couche d'un métal réfractaire, comme du métal au titane, sur le substrat non-conducteur. On dépose ensuite sur la première couche une seconde couche d'un composé réfractaire, comme du nitrure de titane, en suivant la méthode de déposition en phase gazeuse par procédé physique, afin de produire un substrat non-conducteur ayant une meilleure adhérence du revêtement.
