<p>A coated substrate product is disclosed which comprises a substrate and a polycrystalline diamond layer having a smooth surface finish, enhanced crystal orientation in comparison to industrial grde diamond powder particularly in the (220) and (400) directions, and excellent electrical and thermal properties. Also disclosed is a method for fabricating such a coated substrate in which the polycrystalline diamond layer is chemically vapor deposited onto the substrate at substrate temperatures in the range of 650° to 825° C.</p> |
