The invention provides a method for preparing a Ni-Cu corrosion-resistant alloy coating through jet electrodeposition and laser quenching, and belongs to the technical field of metal corrosion protection. Firstly, a nickel plating solution and a copper plating solution are prepared; secondly, a workpiece is placed in the solution, the electroplating carrier is immersed in the plating solution, spraying electro-deposition equipment is used, the electroplating carrier serves as a cathode, a nozzle serves as an anode, the plating solution is sprayed to the electroplating carrier in an electro-deposition mode in sequence, and a Ni-Cu-Ni sandwich structure composite plating layer is formed; and after cleaning and air drying, the plating layer is subjected to laser surface quenching treatment, and the Ni-Cu corrosion-resistant alloy plating layer is obtained. According to the method, the alloy coating with the uniform surface, few pores and good quality can be prepared under the condition that the anti-corrosion pe
