Abstract
A process for building a high-performance liquid flow-through plate is provided and includes providing a substrate formed of metal matrix composite (MMC) material, metallizing a surface of the substrate to reform the surface into a metallized surface, placing a braze foil on the metallized surface and executing a high-temperature and high-pressure bake whereby material of the braze foil diffuses into the metallized surface.

A process for building a liquid flow-through plate, the process comprising:
- providing a substrate formed of metal matrix composite (MMC) material with a surface and a trench recessed into the substrate from the surface;
- metallizing the surface of the substrate to reform the surface into a metallized surface;
- placing a braze foil on the metallized surface and across the trench;
- and
- executing a bake whereby material of the braze foil diffuses into the metallized surface.
A process for building a liquid flow-through plate, the process comprising:
- forming first and second substrates of composite material;
- forming a trench in the first substrate;
- metallizing surfaces of the first and second substrates to reform the surfaces into metallized surfaces;
- placing a conductor in the trench, disposing a fin on the conductor and placing a braze foil on the metallized surface of the first substrate and the fin;
- contacting the braze foil with the metallized surface of the second substrate;
- and
- diffusing material of the braze foil into portions of the metallized surfaces of the first and second substrates whereby the fin forms braze bonds at the trench using the braze foil and the conductor.
A process for building a liquid flow-through plate, the process comprising:
- providing a substrate formed of metal matrix composite (MMC) material with a trench;
- metallizing a surface of the substrate and a surface of the trench to reform the surface of the substrate into a metallized substrate surface and to reform the surface of the trench into a metallized trench surface;
- placing a conductor on the metallized trench surface and a braze foil on the metallized substrate surface and across the trench;
- interposing a fin between the braze foil and the conductor in the trench;
- and
- executing a bake whereby material of the braze foil diffuses into the metallized surface.
