Compared with the patent CN2022104597001, the porous electrode in this embodiment is characterized in that the middle of the porous electrode in this embodiment further has a plurality of injection holes to change the flow direction of the local electrolyte in the inner cavity of the annular workpiece, so that the electrolyte can enter the groove structure on the inner wall of the annular workpiece to flush the groove structure, thereby taking away the heat and bubbles generated by the thermal electrochemical oxidation reaction in the groove, and improving the film forming quality.
Example 1
As shown in figure 1, the porous electrode for processing the cylinder of the internal combustion engine with a groove structure is characterized in that the inner cavity wall of a cylinder 2 of the internal combustion engine is provided with two symmetrical grooves, the porous electrode 1 is a hollow electrode, the lower end of the porous electrode is provided with an insulating plug 4, the middle part of the porous electrode is provided with two symmetrical jet holes 101, and the two symmetrical jet holes correspond to the two grooves on the inner cavity wall of the cylinder 2 of the internal combustion engine respectively. The ejection direction of the ejection holes 101 is perpendicular to the porous electrode 1.
When the inner wall of the internal combustion engine cylinder 2 is subjected to the thermoelectric chemical oxidation treatment, electrolyte flows in from the upper end of the porous electrode 1, enters the internal combustion engine cylinder 2 through the water outlet hole 3, then flows out from an electrolyte outlet on a clamp on the upper part of the internal combustion engine cylinder 2, meanwhile, a part of electrolyte is sprayed out of the spray hole 101 to enter the groove structure, so that the groove is flushed, heat and bubbles generated by the thermoelectric oxidation reaction in the groove are taken away, and the film forming quality in the groove is improved.

As shown in FIG. 2, a porous electrode for processing a bearing outer ring having a ring-groove structure is different from that of embodiment 1 in that the inner wall of the bearing outer ring 2' has a ring-groove, and the porous electrode 1 has 8 injection holes 101 arranged in a ring shape in the middle, and the intervals between the injection holes 101 are the same.
When carrying out the thermoelectric chemical oxidation treatment to bearing inner race 2' inner wall, electrolyte flows in from the upper end of porous electrode 1, gets into bearing inner race 2' through apopore 3, flows out from bearing inner race 2' upper portion again, and meanwhile, partly electrolyte from the blowout of jet orifice 101, gets into the annular groove in, erodees the annular groove surface, takes away the heat and the bubble that the annular groove produced in thermoelectric chemical oxidation reaction, improves the film forming quality of annular groove part.
