Abstract
A process is described that combines combustion in a gas-free (elemental) mixture and forced (centrifugation-driven) infiltration of molten metals into the combustion products. The general mechanism of this process is discussed, and its applicability in producing cermet materials with controlled microstructure is examined. Detailed data are presented for Ti + C/NiO + Ni + Al and Ti + B + Cr/Cu2O + Cu + Al bilayer systems. It is shown that the rate of infiltration of the liquid combustion products in NiO + Ni + Al and Cu2 O + Cu + Al mixtures into pores of Ti + C and Ti + B + Cr layers can be controlled by centrifugation at 1–1000g.
