Abstract
[Problem] To prepare a thin plate having excellent corrosion resistance, conductivity, and formability at low cost. [Solution] A thin plate is prepared by an ultraquenching transition control injector with a mixture of a metal powder having corrosion resistance to form a matrix and a powder having conductivity, as a raw material. An obtained thin plate has a conductive material component that exists, without dissolving, in a metal matrix exhibiting corrosion resistance by passivation, thereby having aforementioned characteristics.
Claims12
A method for manufacturing a thin composite plate, the thin composite plate comprising a conductive material component that exists, without dissolving, in an amorphous metal matrix exhibiting corrosion resistance by passivation, the method comprising:
- providing an injection gun having a plurality of powder ejection ports arranged at equal intervals in a widthwise direction, a plurality of flame vents arranged outside of the powder ejection ports, and a plurality of mist ejection ports arranged further outside of the flame vents for cooling,
- injecting metal used for the metal matrix and the conductive material from the powder ejecting ports of the injection gun with flame ejected from the flame vents toward a substrate so that the metal is melted, and
- then cooling the metal and the conductive material with refrigerant mists ejected from the mist ejection ports before the flame reaches the substrate so as to provide a composite plate with a coating laminated on the substrate.
