| 摘要 |
The invention concerns a bath composition for electropolishing of a non-alloyed titanium metal surface, characterised in that it comprises: sulphuric acid (95 to 98 % solution): 20 to 40 % in volume; hydrofluoric acid (40 to 48 % solution): 10 to 18 % in volume; acetic acid ( 90 to 100 % solution): 42 to 62 % in volume, capable of modifying the electrochemical balances at the solution-metal interface, the acetic acid enabling a better control of oxidation and dissolution of the titanium surface and to automatically limit the chemical dissolution of the metal surface. |
