Abstract (en)

[origin: US2012012402A1] A cutting table includes a lattice structure and a catalyst material deposited within voids formed within the lattice. The catalyst material is deposited in the voids during a sintering process that forms the lattice. The catalyst material has a coefficient of thermal expansion that is less than that of cobalt. The catalyst material is any one of chromium, tantalum, ruthenium, an alloy of cobalt, an alloy of a Group VIII metal and at least one non-catalyst metal, an alloy of two or more Group VIII metals, or a eutectic alloy. In certain embodiments, the catalyst material has a thermal conductivity that is greater than that of cobalt. In certain embodiments, the cutting table is bonded to a substrate, which is formed from a substrate material and a binder material. In some embodiments, the binder material and the catalyst material are the same; while in others, they are different.
