Argon arc cladding material for preparing authigene ceramic phase reinforced iron based wear-resisting layer

The invention discloses an argon arc cladding material for preparing authigene ceramic phase reinforced iron based wear-resisting layer, belonging to the technical field of material surfaces. The argon arc cladding material is characterized by being composed of the following raw materials by mass percent: 60-85% of iron-based self-fluxing alloy powder, 0-5% of titanium powder, 3-8% of zirconium powder, 3-10% of niobium powder, 5-25% of vanadium powder, 2-8% of graphite and 1-3% of rare earth alloy. The cladding material can be prepared into the following two forms: (1) the cladding material is precoated on a work piece surface and is planished, wherein the coating thickness is 0.8-1.5mm; (2) the cladding material is pressed to form a sheet, wherein the sheet is 0.8-1.5mm thick, 6-10mm wide and 50-100mm long, the sheet is dried by airing for more than 10 hours at room temperature, then, is baked for 2 hours at 120-160 DEG C. The argon arc cladding material has low melting point, can be shaped well, and can be
