The invention provides a ZrO2 ceramic surface electric conduction method. The ZrO2 ceramic surface electric conduction method comprises the steps: (1) processing a plurality of grooves in the surface of a ZrO2 ceramic finished product; (2) ball-milling glaze powder, electrically conductive ceramic powder and gloss oil to obtain electric conductive slurry, wherein the glaze powder comprises Al2O3 and SiO2 and further comprises at least one of Na2O, K2O, CaO, MgO, B2O3 and ZnO; (3) carrying out silk-screen printing on the electric conductive slurry at the grooves of the ZrO2 ceramic finished product, and drying to obtain a zirconium oxide blank; and (4) carrying out sintering treatment on the zirconium oxide blank at the sintering temperature of 600 DEG C-1200 DEG C, and then carrying out polishing treatment to prepare the zirconium oxide ceramic with the electrically conductive surface. According to the method, the surface electrically conductive zirconium oxide ceramic is obtained at a relatively low sintering temperature and is resistant to acid and alkali corrosion; and moreover, good electrical conductivity is achieved, a metalized layer is firmly combined with a zirconia ceramic matrix, is not easy to crack and fall off, has a mirror surface effect and does not have macroscopic pores.
