描述了一种将无气体（元素）混合物中的燃烧与熔融金属强制（离心驱动）渗透到燃烧产物中相结合的过程。讨论了该过程的一般机制，并检验了其在生产具有受控微观结构的金属陶瓷材料中的适用性。提供了 Ti + C/NiO + Ni + Al 和 Ti + B + Cr/Cu2O + Cu + Al 双层系统的详细数据。结果表明，NiO+Ni+Al和Cu2O+Cu+Al混合物中的液体燃烧产物渗入Ti+C和Ti+B+Cr层孔隙的速率可以通过1-1000g离心来控制。
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 Cu2O + Cu + Al mixtures into pores of Ti + C and Ti + B + Cr layers can be controlled by centrifugation at 1–1000g.
