Abstract Nickel-based superalloy used in spark plugs was prepared by casting-electroslag remelting-forging-drawing processes. The effects of the processing on the microstructure and oxidation resistance of the Nickel-based superalloys, especially the phase composition and morphology of the formed oxide layers were studied. The results show that, the grain size of casting alloy is large and pores and impurities were found. Electroslag remelting process can improve the purity of the alloy, while reducing the shrinkage of the material. The forging and drawing process can make the grain of the alloy refinement. The oxide layer on the surface of the casting alloy is incomplete and easy to peel off. Weight gain of the casting alloy after oxidation at 900 ℃ for 100 h is 1.74 mg/cm². With the process of electroslag remelting, forging and drawing, the oxide layer becomes complete and compact. Nodular oxides appear on the surface of forging alloy and drawing alloy, and their antioxidant properties are gradually improved. Weight gain of electroslag remelting, forging and drawing alloys after oxidation are reduced to 1.17, 0.71 and 0.51 mg/cm², respectively. Casting, electroslag remelting and forging alloys form a double-layer oxide layers, the outer oxide layer is mainly composed of NiO and NiFe₂O₄, while the inner oxide layer is an enriched area of Cr. After the double-layer oxide layer is formed on the surface of the drawing alloy, a similar double-layer oxide layer is formed inside the alloy, and finally a four-layer oxide layer is formed in drawing alloy.
