The invention provides a method for manufacturing a plated diamond needle, which takes nickel-titanium alloy as a substrate of the needle, and comprises the following steps: firstly, the nickel-titanium alloy substrate of the needle is processed; secondly, the nickel-titanium alloy substrate of the needle and diamond particles are subjected to electroplating pre-treatment; thirdly, a composite diamond clad layer is coated on the head of the needle by means of direct-current electroplating; and fourthly, the diamond needle prepared is subjected to vacuum heat-treatment after electroplating. The method has the advantages that: firstly, the nickel-titanium alloy substrate of the needle has strong impact resistance, and the fracture probability of the substrate of the needle under the actuation of impulsive load is reduced, so that the fracture accident of the substrate of the needle can be effectively prevented; and secondly, due to adoption of the nickel-titanium alloy substrate of the needle and the heat-treatment technology after electroplating, a diffused layer is formed on an interface between the nickel-titanium alloy substrate of the needle and a metallic nickel clad layer, and metallic nickel in the clad layer and titanium in the nickel-titanium alloy substrate of the needle form intermetallic compounds, so that the bonding force of the clad layer is greatly reinforced, and the service life of the diamond needle is further improved.
