Abstract
Official abstract text for this publication.
Refractory coatings for cutting tool applications and methods of making the same are described herein which, in some embodiments, permit incorporation of increased levels of aluminum into nitride coatings while reducing or maintaining levels of hexagonal phase in such coatings. Coatings and methods described herein, for example, employ cubic phase forming compositions for limiting hexagonal phase in nitride coatings of high aluminum content.
First claim
Opening claim text (preview).
That which is claimed is: 1. A coated cutting tool comprising: a substrate; and a coating adhered to the substrate, the coating including a refractory layer deposited by physical vapor deposition and comprising a plurality of sublayer groups, a sublayer group comprising a cubic phase forming nanolayer and an adjacent nanolayer of M 1-x Al x N wherein x≧0.5 and M is titanium or chromium, the refractory layer having 0.5 to 15 weight percent hexagonal phase. 2…
