Embodiment 1

[0044] Embodiment 1 is used for illustrating the polishing method of the amorphous alloy workpiece of the present invention and the polishing liquid that adopts thereof;

[0045] Step 1, pre-treatment: 1) mechanical polishing: the size is 150 × 50 mm 2 The amorphous alloy workpiece is mechanically polished, first with a coarse cloth wheel for rough polishing, then with a wind wheel for semi-fine polishing, and finally with a white cloth wheel for fine polishing, so that the surface roughness of the amorphous alloy workpiece is 0.08-0.15 microns; 2 ) Ultrasonic degreasing: 20g / L Na 2 CO 3 with 25g / L Na 3 (PO 3 ) 2 1000mL of the mixed solution was heated to 40°C; the amorphous alloy workpiece was ultrasonically cleaned in the above solution for 5 minutes, taken out, and cooled to room temperature; 3) Washing: soak the amorphous alloy workpiece in pure water for 1 minute;

[0046] Step 2, plasma polishing:

[0047] 1) Preparation of polishing liquid: prepare 1L of polishing...

Embodiment 2

[0055] The difference between embodiment 2 and embodiment 1 is that the content and polishing conditions of each component in the polishing solution in the plasma polishing step are different: wherein,

[0056] 1) In the polishing liquid, the content of each component is:

[0057] Sodium sulfate: 12g / L Ammonium sulfate: 15g / L Ammonium bifluoride: 1g / L

[0058] Cerium sulfate: 30ppm Organic phosphonic acid: 2g / L Benzotriazole: 1g / L Sodium citrate: 20g / L

[0059] Sodium sulfosuccinate: 1mL / L Sodium ethylhexylsulfonate: 3ml / L

[0060] 2) The conditions for plasma polishing are: set the pulse working voltage to 340V, pulse frequency to 12KHz, duty cycle to 10%, operating temperature to 80°C, and polish for 4 minutes;

[0061] Amorphous alloy piece A2 was obtained after plasma polishing.

Embodiment 3

[0063] The difference between Example 3 and Example 1 is that the content of cerium sulfate in the polishing liquid is 15 ppm, and the amorphous alloy piece A3 is obtained after plasma polishing.

Abstract

The invention provides a polishing solution used for an amorphous alloy and a polishing method of an amorphous alloy. The polishing solution comprises: a sodium salt, an ammonium salt and a brightener, i.e. ceric sulfate. The polishing method includes plasma polishing to an amorphous alloy. And the plasma polishing method consists of: connecting the amorphous alloy to a positive electrode, and immersing the amorphous alloy into an electrolytic cell containing the polishing solution, and taking the electrolytic cell body as a negative electrode for plasma polishing. The amorphous alloy prepared with the polishing solution provided in the invention and by the plasma polishing method of the invention has a smooth surface and high surface reflectivity.

Description

Technical field [0001] The invention involves the surface treatment field of amorphous alloys. Specifically, it involves a polishing method for polishing fluid for amorphous alloy and a polishing method of an amorphous alloy. Background technique [0002] At present, the appearance requirements of metal parts are getting higher and higher, especially the metal parts used in electronic products. The comprehensive requirements of the surface roughness and surface reflectance parameters are becoming stricter.The surface treatment of general metal parts includes polishing, anode oxidation, micro -oxidation, and electroplating.Among them, polishing can be used as a preferred process for the surface treatment of metal parts to effectively improve the surface performance of the metal parts. It can also be used as a preliminary process of various (including special functions) surface modification technology to provide convenience for subsequent processing. [0003] A amorphous alloys are...
