Electrochemical deburring of laser treated nickel sheets



"Deburring and Edge Finishing" by Laroux K Gillespie

(affil link)

Hi, we currently have the problem of electropolishing/deburring nickel sheets that have been engraved by means of a laser. Typical engraving depth is around 50 microns. After lasering of the sample the engraved area is covered with nickel-oxide.

The main problem is that the burrs created during the laser etching cannot be fully removed with the electrolyte we've tried so far (Combinations of sulfuric Acid, Phosphoric Acid and Hydrochloric Acid) with Current Densities up to 20 Amps/dm2. After treatment there are still some edges of the engraving that are higher than the surface plane.

Could you please give me advice on optimized (electro) chemical deburring techniques for nickel and the experience you had with them?

Best regards,
