Abstract
In one aspect, methods of making coated articles are described herein. A method, in some embodiments, comprises providing a substrate, and depositing a coating by chemical vapor deposition (CVD) and/or physical vapor deposition (PVD) over a surface of the substrate, the coating comprising at least one polycrystalline layer, wherein one or more CVD and/or PVD conditions are selected to induce one or more properties of the polycrystalline layer. The presence of the one or more properties in the polycrystalline layer is quantified by two-dimensional (2D) X-ray diffraction analysis.
Claims17
A coated article comprising:
- a substrate;
- and
- a coating comprising a layer of alumina adhered to the substrate, wherein less than 50 volume percent of grains in the alumina layer have random orientation as quantified by 2D X-ray diffraction analysis.
