Abstract
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.
