Method for electroplating diamond roller coating with introduction of pulsed power supply

The invention discloses a method for electroplating a diamond roller coating with introduction of a pulsed power supply and belongs to the technical field of electroplating of diamond roller coatings. The electroplating method comprises the following steps: putting a sanded female die into a plating solution; regulating the power supply to a direct current output state, and regulating the current output quantity, wherein the output current density is set to be 0.65-1 ampere per square centimeter; connecting the power supply, wherein the electroplating time is 1-2 weeks; cutting power supply of the direct current power supply until the electroplating operation is ended, wherein the thickness of the coating is 0.3-0.6mm; regulating the current to a pulse output state, and regulating the current output quantity, wherein the output current density is set to be 1-2.5 amperes per square centimeter, the pulse frequency is set to be 1000Hz, and the duty ratio is set to be 25-50 percent; connecting the power supply, wherein the electroplating time is 3-4 weeks; cutting power supply of the pulsed power supply until the electroplating operation is ended, wherein the thickness of the coating is 1.5-2.5mm; taking the female die electroplated with the coating out of the plating solution.
