Embodiment 1

[0026] The workpiece 3 is aviation aluminum, and the specific shape is as follows figure 1 shown.

[0027] Workpiece 3 is processed as figure 1 As shown, a hole with a diameter of 6 mm is punched in the upper left corner of the workpiece 3 for connecting with the positive lead of the double pulse power supply 1 .

[0028] The treatment process of workpiece 3 is to grind it with 240#, 400#, and 800# sandpaper in sequence, then put it into acetone solution for two 10-min ultrasonic cleaning, and then use an ordinary hair dryer to dry it and pack it into a bag for later use.

[0029] The parameters of the double pulse power supply 1 are set by the main control computer 2 through the RS485 protocol.

[0030] The surface morphology was observed with a TESCAN VEGA-XMU scanning electron microscope to observe the surface microscopic morphology of the ceramic film.

[0031] The thickness of the film layer is measured with an eddy current thickness gauge, and 8 points are taken for...

Abstract

The invention discloses a laser-assisted atomization micro-arc oxidation device which comprises a dual-pulse power supply, a main control computer, a workpiece, a circulation pump, an electrolytic cell, an atomization device, a cathode module and a numerical control machine tool moving spindle. For the device, by performing laser-assisted atomization, the concentration of an electrolyte jetted byan atomization head under the circulation effect of the atomization device and distribution of conductive ions in a solution are uniform, the problem of solution fluctuation brought by a stirring device is solved so as to solve the problem that potential is lacked self in the existing micro-arc oxidation method, a generated electric field environment is uniformly distributed, and the uniformity ofprocessing the surface of the workpiece is improved. Meanwhile, laser light of a pulse laser in a cathode sleeve illuminates the workpiece laterally, metal ions on the surface of the workpiece acquires energy, an auxiliary electrode activates the metal activity of the surface of the workpiece, and the cathode module exerts the auxiliary heating effect to the workpiece, so that the limitation of the workpiece in a large size to a power of a power supply is solved.

Description

technical field [0001] The invention relates to the field of micro-arc oxidation, in particular to the processing of laser-assisted spray micro-arc oxidation technology for complex workpieces or large-area workpieces, in particular to a laser-assisted spray micro-arc oxidation device. Background technique [0002] At present, most domestic micro-arc oxidation processing on the surface of workpieces directly immerses the workpiece in the electrolyte as the anode, and connects the electrolytic cell to the cathode of the power supply as the cathode. The cathode area is relatively large, and there is no relative movement between the cathode and anode. Finally, the simultaneous processing of the workpiece surface is realized. This processing method is highly dependent on the power of the power supply, so the requirements for the power of the power supply are very strict, and the arcing area is uncontrollable. Due to the non-uniformity of conduction and heating, there will be tip...
