| Abstract: | The coating of nano‐Cr2O3 was successfully fabricated via aqueous electrophoretic deposition (EPD). The deposition behavior aqueous nano‐Cr2O3 suspension was affected by the added amount of nitric acid. The morphology of electrophoretic Cr2O3 coating was significantly influenced by the deposition voltage. For a suitable EPD, stable aqueous nano‐Cr2O3 suspension could be obtained by the addition of 0.0025 M nitric acid, and the suitable deposition voltage was 5 V. For the purpose of increasing deposition rate which was limited by lower deposition voltage, it was suggested to employ higher suspension concentration of Cr2O3. |
