The invention discloses an iron-based amorphous welding material for twin-wire arc cladding. The iron-based amorphous welding material comprises Fe–Cr–Mo–C–B–Y–Ni, with the atomic formula: FeaCrbMocCdBeYfNig, where a = 100 − b − c − d − e − f − g, 11 ≤ b ≤ 14.5, 9 ≤ c ≤ 14, 9 ≤ d ≤ 18, 5 ≤ e ≤ 8, 1.5 ≤ f ≤ 2.5, 5 ≤ g ≤ 7. The material of the invention is characterized by using 304 L stainless steel (main component elements: Fe: 70.1%, Cr: 19.3%, Ni: 10.6%) as the cladding material to wrap the core materials Mo powder, C powder, FeB powder, and rare earth Y powder. The twin-wire arc cladding process can produce a cladding layer with a thickness of millimeters, nearly 100% amorphous state, and excellent corrosion and wear resistance.

The iron-based amorphous welding material comprises Fe–Cr–Mo–C–B–Y–Ni, with the atomic formula: FeaCrbMocCdBeYfNig, where a = 100 − b − c − d − e − f − g, 11 ≤ b ≤ 14.5, 9 ≤ c ≤ 14, 9 ≤ d ≤ 18, 5 ≤ e ≤ 8, 1.5 ≤ f ≤ 2.5, 5 ≤ g ≤ 7. The material of the invention is characterized by using 304 L stainless steel (main component elements: Fe: 70.1%, Cr: 19.3%, Ni: 10.6%) as the cladding material to wrap the core materials Mo powder, C powder, FeB powder, and rare earth Y powder. The twin-wire arc cladding process can produce a cladding layer with a thickness of millimeters, nearly 100% amorphous state, and excellent corrosion and wear resistance.
