1. A process for building a high-performance liquid flow-through plate, the process comprising:
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 bake whereby material of the braze foil diffuses into the metallized surface, the process further comprising:
forming a trench in the substrate, wherein the metallizing of the surface of the substrate comprises metallizing surfaces of the trench;
placing a conductor in the trench; and
interposing a fin between the braze foil and the conductor.
