Performance of boron nitride coated tools and dies
Boron Nitride (BN) coating technology is developed to supply this need [2]. Boron nitride is mostly found in two polymorphs in the coatings; hexagonal boron nitride (h-BN) and cubic boron nitride (c-BN). Hexagonal boron nitride is well-known as a soft material with low friction coefficient used for lubricating at both low and high temperatures.
