The advantages and dis2 advantages in physicaldeposition techniques ofnitride coatingswith multi2constituent andmultilayerwere analyzed. The toolnitride coatingshave developed from singlemetalnitride coatings tobinary constituent alloy coatings andmulti2con2 stituent coatings. The numbers of layers ofthe coatingshasbeen mi proved from single layer tomultilayer, and thenano2 composite coatings are now the development trend. N itride coatingswithmulti2constituent andmultilayerwillbe the re2 search interest oftoolcoatings in the future.
