| titleOfInvention | A hexavalent iron ion solution production method, a magnesium alloy chemical conversion treatment agent and treatment method, and a resin surface etching method. |
| abstract | The present invention relates to a chemical conversion treatment method using a hexavalent iron ion solution with a low environmental load, and a chemical conversion treatment method using a hexavalent iron ion solution having a low environmental load instead of a chemical conversion treatment agent such as harmful chromic acid, which has been used to improve corrosion resistance of members such as magnesium alloys. A chemical conversion treatment agent is provided from a valent iron ion solution. An electrolytic membrane partitioned by an cation-exchange membrane or a bipolar membrane is filled with a predetermined alkaline aqueous solution on the anode side of the electrolytic cell and a predetermined alkaline aqueous solution on the cathode side, and an anode made of iron is installed, A stable hexavalent iron ion solution is obtained by installing a cathode composed of an arbitrary conductive cathode and then supplying a predetermined power from a DC power source and eluting the anode composed of iron into the aqueous solution as hexavalent ions. Can do. Moreover, the chemical conversion treatment member 11 which has the chemical conversion treatment film excellent in corrosion resistance equivalent to chromium oxidation treatment is obtained by performing chemical conversion treatment on the magnesium alloy member 10 using the liquid agent containing the stable hexavalent iron ions. be able to.
