Abstract
A metal-ceramic composite includes a ceramic matrix defining a multiplicity of pores, and a metal electrodeposited in the multiplicity of pores. A ceramic slurry includes ceramic microstructures or nanostructures, silica nanopowder, a dispersant, and a binder. Repairing a void in a metal-ceramic composite, wherein the void is defined by at least a first metal surface and a second metal surface of the metal-ceramic composite, includes introducing a solution including metal ions into the void, and electrodepositing the metal ions on the first metal surface and the second surface to yield a metal phase, thereby filling the void.
