Embodiment 1
[0037] like Figure 1 to 5 As shown, embodiments of the present invention provide a method of preparing a metal matrix amorphous coating, including steps S101 to S103:
[0038] S101: Chemical plating of amorphous powders, forming a layer of metal layer after chemically plating, producing an amorphous metal composite powder, the electrical conductivity of the metal layer is 9.93 * 10 6 ~ 6.3 * 10 7 S / m.
[0039] Among them, the amorphous powder can be a different series of amorphous powders, the shape is not limited, and the particle size is 10 to 100 μm.
[0040] The metal layer can take iron, cobalt, chromium, and the like, and the electrical resistivity corresponding to 1.65 * 10 -8 ~ 9.78 * 10 -8 (Ω · m), for high conductivity material.
[0041] The amorphous powder is chemically plated such that the amorphous powder surface forms a layer of metal layer, and the non-alcoholic metal composite powder is prepared, and the electrical conductivity range of the metal layer is 9.93 *...
Embodiment 2
[0066] FE-CO-CR-MO-C-B-Y is prepared at 304 stainless steel surface, and the obtained amorphous powder component is FE-Co-Cr-Mo-C-B-Y, the particle size is 50 μm, which is a spherical powder, and the plating solution is a copper sulfate solution.
[0067] First, 300 to 400 destination FE-based non-crystalline powders were placed in the NaOH solution and then removed, and then poured into the FE-based amorphous powder of the formulated sensitization into the oil, stirred for 30 min, to be powder After completely settlement, filtered, dried, and the FE-based amorphous powder was obtained.
[0068] The formulated activated liquid is poured into the sensitized Fe group, stirred for 10 min, and filtered after the powder is completely settled. After filtering with distilled water, it is activated to activate the FE-based amorphous powder, activating liquid Choose 2g / L AGNO3 solution.
[0069] The activated FE-based amorphous powder was poured into a copper sulfate solution, and the co...
