The invention discloses a preparation method of Ni-W-Cu/nanoceramic multilayer alloy. The method comprises the following steps that (1) Ni-W-Cu electrolyte is prepared; (2) nanoceramic particles are pretreated; (3) the nanoceramic particles obtained in the second step are dispersed in the Ni-W-Cu electrolyte prepared in the first step to obtain Ni-W-Cu/nanoceramic electrolyte; (4) a plating element is put into the Ni-W-Cu/nanoceramic electrolyte prepared in the third step; a double current cycle step method is used for electrodeposition; after the electrodeposition is completed, the plating element is taken out and is cleanly flushed; natural drying is performed. The preparation method of the Ni-W-Cu/nanoceramic multilayer alloy provided by the invention has the advantages that an obtained plating layer has good corrosion resistant performance and good abrasion performance; the nanoparticles are uniformly dispersed; the alloy crystalline grain is fine; the plating layer is of a multilayer composite structure, so that potential application prospects are realized.
