Titanium etching solution and application thereof

The invention discloses a titanium etching solution and application thereof.The titanium etching solution is prepared from, by mass, 88.75-96.25 parts of water, 2.5-7.5 parts of ferric salt and 1.25-3.75 parts of ammonium bifluoride, the mixing ratio of the ammonium bifluoride to the ferric salt is kept to be 1: 2, the ferric salt and the ammonium bifluoride can be directly used after being mixed in an aqueous solution according to the ratio, and compared with a traditional preparation mode, the titanium etching solution is safer, and the application range of the titanium etching solution is widened. The hydrofluoric acid is not directly used, and the hydrofluoric acid is not generated in the preparation process and the use process, so that harmful toxic smoke is not generated, and the method is good for the human body and the environment. 本发明公开了一种钛蚀刻液及其应用，包括下列质量浓度的各组分：水88.75-96.25份、铁盐2.5-7.5份，以及氟化氢铵1.25-3.75份，氟化氢铵与铁盐的混合比例保持1:2，本发明的同时铁盐与氟化氢铵按比例在水溶液混合后可以直接使用，相对传统的配制方式更加安全，由于不直接使用氢氟酸，并且在配制过程和使用过程也不会产生氢氟酸，也就不会产生
