    摘要: The present invention provides a functionally graded glass/ceramic/glass sandwich system for use in damage resistant, ceramic and orthopedic prosthesis. The functionally graded glass/substrate/glass composite structure comprises an outer residual glass layer, a graded glass-ceramic layer, and a dense interior ceramic. The functionally graded glass/substrate/glass composite structure may further comprise a veneer on an exterior surface. The present invention also provides a method for preparing a functionally graded glass/ceramic/glass sandwich system. A powdered glass-ceramic composition is applied to the accessible surfaces of a presintered zirconia substrate to thereby substantially cover the substrate surfaces. The glass of the composition has a CTE similar to that of the substrate material. The glass-ceramic composition is infiltrated into and densifies the substrate by heating the assembly to at least the sintering temperature of the substrate.

    摘要: A method of installing an acoustical system that provides a desired sound attenuation includes attaching an acoustical panel having a first density, a first porosity and a first void volume to the substrate. A first finishing layer is prepared with first particles, a first binder, a first rheological modifier and water which are combined, applied to the substrate and dried. The first finishing layer has a first density. When the first sound attenuation changes to a second sound attenuation a second finishing layer is prepared to include second particles, a second binder, a second rheological modifier and water. The dried second finishing layer has a second density. If the second density is less than the first density, the second sound attenuation is greater than the first sound attenuation. If the second density is greater than the first density, the second sound attenuation is less than the first sound attenuation.
