Apparatus and method for blue laser-enhanced abrasive flow composite electrochemical polishing of Inconel 718 alloy

Abstract

The application discloses a device and a method for blue laser enhanced abrasive grain flow composite electrochemical polishing of Inconel 718 alloy, and is characterized in that the device comprises a blue laser, a direct-current electrolysis power supply, a cathode clamp, an anode clamp, an electrolyte tank, a reaction tank, a workpiece support table and a two-dimensional fast motion sliding table; the device adopts blue laser lateral assistance, adds abrasive grains in the electrolyte, accelerates the efficiency of the jet electrochemical polishing, simultaneously irradiates through the lateral synchronous assistance of the laser, and simultaneously realizes the two-dimensional sliding table fast motion, so that the lap mark problem existing in the traditional jet polishing is solved, the effect of selective polishing is realized through the jet, the polishing efficiency of the Inconel 718 alloy is effectively improved, the selective and efficient mirror surface polishing effect is realized, the roughness is obviously reduced, the device is safe and feasible, and can be applied to the polishing of high-temperature alloys in future industries.
