Abstract:
A liquid-solid rolling bonding method for heterogeneous metals, comprising:pouring a liquid metal onto the surface of a heterogeneous solid base metal coated with a soldering flux; rolling the liquid metal and the solid metal under pressure; and solidifying the liquid metal to make it bond to the surface of the solid base metal under rapid cooling to realize metallurgical bonding for the two or more metals, wherein the soldering flux is a 6-12% by weight aqueous solution of a composite salt consisting of KF, NaF, KI, Nal and LiI, and the composite salt consists of 15-25% by weight KF, 15-25% by weight NaF, 15-25% by weight KI, 15-25% by weight NaI, and 15-25% by weight LiI.
