Embodiment 1

[0031] Example 1 Surface Treatment of Amorphous Alloys

[0032] After cleaning the mold with dry ice, put it into amorphous alloy, then spray electrostatic powder coating (Akesu medium powder), cover the surface of the high temperature mold with a layer of medium powder evenly, and then pass high temperature die casting (temperature 180 degrees Celsius, time 2min) to make the thickness The powder coating of about 50 microns is transferred to the surface of the amorphous alloy material, thereby eliminating the holes caused by insufficient fluidity, and then the flash burrs are removed by local polishing.

[0033] Spray nano UV coating (coating from Shanghai Feiteng New Material Technology, model UVA021) to the sealed and partially polished amorphous alloy material to make the surface have a high-gloss mirror appearance or anodized matte appearance, infrared baking at 70 degrees Celsius for 6 minutes Rear UV500-3000mj / cm 2 After curing, the solidified amorphous alloy is subject...

[0039] Example 2 Performance testing of amorphous alloy after surface treatment

[0040] The performance test of the treated amorphous alloy obtained in Example 1 is as follows:

[0041] 1) The copper ion accelerated salt spray test is carried out according to the ASTM-B368-97 standard, and the salt spray resistance time of the sample is 16H.

[0042] 2) The acid salt spray test is carried out according to the ASTM-B368-7 standard, and the acid salt spray resistance time of the sample is 96H.

[0043] 3) The cold and heat cycle test is carried out according to the A112.18.1-2005 standard. The results show that after 20 consecutive temperature cycles (-40°C-25°C-75°C-25°C), the sample does not have any morphology change.

[0044] 4) Wipe resistance test, carried out according to ASTM-2486-06 standard, the test result is 1500 times, the film layer does not penetrate the bottom, indicating that the film layer has good abrasion resistance.

[0045] 5) The binding force test is c...

Abstract

The invention relates to an amorphous alloy surface treatment method. The amorphous alloy surface treatment method comprises hole sealing, curing and film plating; and an amorphous alloy has an air hole in the surface. The amorphous alloy surface treatment method is simple and efficient, and can enable the prepared amorphous alloy to have the advantage of delicate appearance; and the amorphous alloy treated by the method is high in corrosion resistance, compact in combination of a plating film and an amorphous alloy matrix and excellent in wear resistance.

Description

technical field [0001] The invention relates to a surface treatment technology, in particular to a surface treatment method of an amorphous alloy. Background technique [0002] Amorphous alloys have atomic arrangements that are completely different from crystalline alloys, which makes amorphous alloys have higher strength, hardness, corrosion resistance, better magnetic properties, superplastic forming and micro-nano forming than crystalline alloys. In the prior art, the forming technology of amorphous alloys mostly adopts the pressure casting forming process for near-final forming, which has the advantages of high production efficiency and is easy to produce high-precision and complex product parts. However, due to the poor surface compactness of the amorphous alloy castings prepared by the casting process and the high strength and hardness of the amorphous alloys, it is difficult to cut the amorphous alloy castings once they are formed. , surface polishing and other treat...
