    Abstract: The present invention provides a coated article comprising a substrate that can be non-crystalline or crystalline such as a polycrystalline engineering material, having advantageous mechanical properties and a superlattice-type protective composite coating on the substrate. The composite coating comprises a plurality of vapor deposited, ion bombarded, polycrystalline layers of different adjacent compositions formed one atop the other in lamellar manner. The polycrystalline layers have sufficiently thin individual layer thicknesses (e.g. not exceeding about 150 nanometers) and sufficiently distinct and different compositions proximate their interfaces despite being ion bombarded as to constitute superlattice layers that exhibit a collective hardness exceeding the hardness of any individual layer material in homogenous or bulk form. The composite coating is ion bombarded to an extent that the individual layers are substantially free of intragranular voids without adversely affecting the compositional modulation of the superlattice layers. Moreover, the composite coating can have planar or non-planar interlayer interfaces and still exhibit substantially improved hardness.

    Abstract: The coating system comprises: at least one layer of type A, a layer of type A substantially consisting of (AlyCr1-y)X, wherein X depicts one of the group consisting of N, CN, BN, NO, CNO, CBN, BNO and CNBO, y describing the stoichiometric composition of the metallic phase fraction; and at least one layer of type B, a layer of type B substantially consisting of (AluCr1-u-v-wSivMew)X, wherein X depicts one of the group consisting of N, CN, BN, NO, CNO, CBN, BNO or CNBO, and wherein Me depicts one of the group consisting of W, Nb, Mo and Ta or a mixture of two or more of the constituents of that group, u, v and w describing the stoichiometric composition of the metallic phase fraction. A thickness ratio of said layer of type A to said layer of type B is higher than 1. The workpiece comprises such a coating system. Through this, an excellent wear-protection is provided, and the coating system and workpieces can be used for a broad range of different applications. The coating system can be deposited very efficiently in a PVD process using two types of targets, wherein targets of one type are active during depositing a layer of type A and during depositing a layer of type B.

    Abstract: The disclosure is for a film coating which yields increased life for optical media molds and the method and apparatus for making such a film. The film is a carbon nitride layer of 0.5 to 5.0 microns thickness with 2% to 45% nitrogen coated on an underlayer. One method of making the carbon nitride film is by the use of a pulsed carbon arc to generate a carbon plasma while injecting nitrogen into the vacuum chamber in which the arc is created. Another method is to generate a radio frequency plasma in a vacuum chamber into which acetylene and nitrogen gas are injected. The carbon nitride is formed by the combination of nitrogen with the carbon from the acetylene.
