The invention relates to the technical field of anti-corrosion coatings, and discloses a centrifugal pump flow passage component with a composite anti-corrosion coating and a preparation method and application of the centrifugal pump flow passage component. The centrifugal pump flow passage component comprises a centrifugal pump flow passage component body. The zirconia ceramic membrane layer is arranged on the surface of the centrifugal pump flow passage component; the silane coating is arranged on the zirconia ceramic film layer; and an electrophoretic coating layer disposed on the silane coating layer. The flow passage component is subjected to three main procedures of zirconium treatment, silane treatment and cathode electrophoretic coating, and the surface of the flow passage component is coated with a composite anti-corrosion coating composed of a zirconium oxide ceramic film layer, a silane coating and an electrophoretic coating through proper zirconium liquid, silane treatment liquid and electrophoret
