Etching solution and application thereof

The present disclosure relates to the technical field of etching. More specifically, the present disclosure relates to an etching solution and an application thereof. A preparation raw material of the etching solution includes at least one oxidant, at least one stabilizer, and deionized water. Through the combined action of hydrogen peroxide and stabilizer, the etching solution of the present disclosure has the good stability, the longer service life, the faster etching rate and the better stability of the etching rate, and the etching solution of the present disclosure has a good etching effect on a titanium-series metal.
