ALUMINUM TITANIUM NITRIDE COATING AND METHOD OF MAKING SAME

摘要

Hard coatings and methods of making the hard coatings comprising aluminum titanium nitride which are usable on cutting tools are disclosed. The coatings include at least one aluminum titanium nitride layer having between about 0 and about 15 weight percent hexagonal phase and a composition of (AlxTi1-x)N, where x is in the range of about 0.53 to about 0.58 moles.
