Abstract

The invention discloses an electroetching solution used for electroetching of an amorphous alloy member and an etching method. The electroetching solution contains 5 to 15 wt% of a polishing agent, 5 to 15 wt% of an etchant and 0.7 to 7 wt% of a corrosion inhibitor. The etching method comprises the following steps: arranging a mask on the surface of the amorphous alloy member; carrying out chemical etching on the amorphous alloy member provided with the mask on its surface by using a chemical etching solution; carrying out electroetching on the amorphous alloy member having undergone chemical etching by using the electroetching solution; and removing the mask on the surface of the amorphous alloy member after electroetching so as to obtain the amorphous alloy member with an etched pattern. With the etching method for the amorphous alloy member in the invention, etching precision and dimension can be effectively controlled, an etched region is allowed to have smooth shading and high glossiness, and surface decorative performance of the amorphous alloy member is improved.

Description

technical field [0001] The present invention relates to an etching solution and an etching method, more specifically, the present invention relates to an electroetching solution and an etching method for electroetching an amorphous alloy material piece. Background technique [0002] Currently, a metal surface decoration method has been disclosed on the market, wherein the method includes forming a pattern on the surface of the metal substrate by silk screen printing, followed by chemical etching, electrochemical polishing and depositing a metal layer in sequence. Among them, the electrochemical polishing step is used to moderately polish the etched metal plate, so that the glossiness of the etched part of the decorated metal plate is increased from below 20GU in the prior art to above 70GU, and the glossiness of the non-etched part is 600GU As mentioned above, the decorated metal plate can obtain the effect of bright and semi-brightness, thereby improving the appearance and ...
