Claim 0:
1. A method of preparing a substrate having a wetting surface, comprising:
a) confirming the presence of an open, interconnected pore network in a ceramic substrate to be wetted with a first metal;
b) filling the open, interconnected pore network with a second metal;
c) heating the substrate to exude second metal from the interconnected pore network to coat the surface of the substrate; and
d) wetting the substrate with the first metal;
wherein upon cooling the substrate after step c), the second metal withdraws back into the interconnected pore network;
wherein after step b), the second metal is completely disposed in the interconnected pore network;
wherein the ceramic substrate is not decomposed by the first metal; and
wherein the ceramic substrate is not decomposed by the second metal.
