REFRACTORY METAL INKS AND RELATED SYSTEMS FOR AND METHODS OF MAKING HIGH-MELTING-POINT ARTICLES
20170226362 · 2017-08-10 · ·

Thin films of precious metals such as platinum and gold have the required ability to withstand high temperatures, but in pure form can suffer from grain growth, agglomeration and dewetting at high temperature. Grain boundaries must therefore be pinned by alloying with other metals and/or by inclusion of non-metallic nanoparticles. While such bulk materials are known in the prior art, they have not existed previously as printable inks that can be deposited by additive manufacturing direct-write methods. These materials have been formulated for the first time as alloy and composite inks so that they may be applied by direct-write additive manufacturing techniques directly onto three-dimensional components or on high temperature substrates that can be adhered to complex components.

METHOD FOR METAL VAPOR INFILTRATION OF CMC PARTS AND ARTICLES CONTAINING THE SAME

A method comprises discharging from a metal vaporization device a vapor of a metal or a metal precursor to a chemical vapor infiltration device where the chemical vapor infiltration device is in fluid communication with the metal vaporization device. The chemical vapor infiltration device contains a preform containing ceramic fibers. The preform is infiltrated with a metallic coating or a coating of a metallic precursor along with a ceramic precursor coating. The metallic coating and/or the metallic precursor coating and the ceramic precursor coating are applied sequentially or simultaneously.
