1. A coated substrate comprising:

  • a substrate; and

    a coating for enhanced scratch resistance, the coating comprising at least one high refractive index transparent hard material layer, wherein the hard material layer includes crystalline aluminum nitride and wherein the aluminum nitride has a hexagonal crystal structure exhibiting a predominant (001) preferred orientation of at least one of the following;


    x(001)=I(001)/(I(001)+I(100)), and
    y(001)=I(001)/(I(001)+I(101)),as determined by an XRD measurement of the coating, that is greater than 0.5.
