description The present invention discloses a method for preparing a nickel coating on a ceramic surface by using an in-situ reduction method. The method comprises: coating a roughened ceramic surface with PVA sol; preserving heat in a heating furnace under a temperature of 80-100 DEG C; then raising the temperature to 600 DEG C and preserving the heat, so as to completely decompose PVA; then vacuuming the heating furnace; under the condition of argon protection, introducing hydrogen into a heating box to perform in-situ reduction, and meanwhile raising the temperature to 900-1000 DEG C, and preserving the heat. According to the present invention, by a sol-gel method, required raw materials are mixed uniformly in a liquid phase, and compared with particles, the sol has fluidity, film forming property and a property so that the sol can be continuously, uniformly and compactly attached to ceramic matrixes with various complex shapes; a PVA film comprising NiCl2 is prepared on the ceramic surface, then the ceramic surface is coated precisely, continuously and uniformly with the nickel coating by the in-situ reduction method; and by adjusting the mass fraction of nickel salt in the PVA sol, the thickness of the obtained coating is controllable, and the bonding force with the matrix is favorable.
