  • Publication number: 20150137404
    Abstract: The invention relates to a novel process for commercial production of bulk functionally graded materials (FGM) with a per-determined axial, radial, and spherical gradient profiles. The process is based on the reiterated deformation of the layers of variable cross-section thicknesses made of different materials. That allows significant savings of time, energy and materials. Metals, ceramics, glasses and polymers in different combinations can be brought together with a continuous or stepwise gradual change from one material to another. The invention can be applied to industrial production of functionally graded materials with different types of gradient profiles, which cannot be produced by the existing technologies and which are sought by many key industries. The mechanical, thermal and optical responses of materials produced by the proposed methods are of considerable interest in optics, optoelectronics, tribology, biomechanics, nanotechnology and high temperature technology.

    Abstract: A gradient optical film and an optical construction including the gradient optical film are described. The gradient optical film includes a binder, a plurality of particles, and a plurality of interconnected voids having a local volume fraction. The local volume fraction of the plurality of interconnected voids varies along a thickness direction of the gradient optical film. The refractive index of the gradient optical film can also varies along a thickness direction of the gradient optical film, as the refractive index can also depend upon the local volume fraction of the plurality of interconnected voids.

  • Publication number: 20120177908
    Abstract: This invention relates to thermal spray coatings on a metal or non-metal substrate. The thermal spray coating comprises a ceramic coating having a functionally graded porosity across the ceramic coating thickness. The ceramic coating includes an inner layer and an outer layer. The inner layer has a porosity at or near the interface of the inner layer and the metal or non-metal substrate sufficient to provide a compliant ceramic coating capable of straining under thermal expansion mismatch between the ceramic coating and the metal or non-metal substrate at elevated temperature. The outer layer has a decreasing porosity extending from the surface of the inner layer to the surface of the ceramic coating sufficient to provide corrosion resistance and/or plasma erosion resistance to said ceramic coating. This invention also relates to methods of protecting metal and non-metal substrates by applying the thermal spray coatings.
