example 1

[0055]A commercially available 2mm thick A5052 aluminum alloy plate was purchased, and the aluminum alloy was uniformly cut into 20mm×10mm aluminum sheets by wire cutting. Select iron sandpaper of models 360#, 600#, and 800# in order for grinding. When grinding, the sample must be rotated 900 every time the sandpaper is changed to ensure that all the scratches left by the previous process are removed, so that the thickness of the sample reaches about 5um, and then use ethanol solution to clean in ultrasonic for 10 minutes to remove Surface oil stains were cleaned with deionized water and dried in a drying oven at 120°C.

[0056] Prepare 100ml of NaOH solution with a mass concentration of 2% with ion-exchanged water, heat it to 40°C in a water bath, dip the aforementioned aluminum alloy sheet in this solution for 2 minutes in a hanging manner, and then wash the aluminum alloy sheet with deionized water clean.

[0060] A commercially available 2 mm thick A6063 aluminum alloy plate was purchased, and the aluminum alloy was uniformly cut into aluminum sheets of 20 mm×10 mm by wire cutting. A small hole is opened on each aluminum alloy sheet, and the surface is polished with iron sandpaper of models 360#, 600#, and 800# in sequence. When grinding, every time a sandpaper is changed, the sample is rotated 900 to ensure that all the scratches left by the previous process are removed, so that the thickness of the surface of the sample is removed to a level of about 5um, and then the ethanol solution is used to clean it in ultrasonic waves for 10 minutes. Remove the surface oil, then rinse it with deionized water, and dry it in a drying oven at 120°C

[0061] Prepare 100ml of NaOH solution with a mass concentration of 2% with ion-exchanged water, heat it to 40°C in a water bath, dip the aforementioned aluminum alloy sheet in this solution for 2 minutes in a hanging manner, and then clean the ...

[0065] Commercially available aluminum foil was purchased and cut into thin slices of 20mm×10mm. A small hole is opened on each sheet, and the surface is directly polished with 800# iron sandpaper, and then cleaned with ethanol solution in ultrasonic for 10 minutes to remove surface oil, then cleaned with deionized water, and placed in a 120°C drying oven dry

[0066] Prepare 100ml of NaOH solution with a mass concentration of 1.5% in ion-exchanged water, heat it in a water bath to 40°C, immerse the aforementioned aluminum foil in the solution for 2 minutes in a hanging manner, and then clean the aluminum foil with deionized water.

[0067] Next, prepare 100ml of HNO3 solution with a mass concentration of 1% in ion-exchanged water, heat it to 40°C in a water bath, and immerse the above-mentioned alkali-washed aluminum foil in this solution for 1 minute in a hanging manner. Then the aluminum foil was cleaned with deionized water.

[0068] Then use the aluminum foil as the ano...

Abstract

A micro-nano processing method of an aluminum or aluminum alloy surface includes a step of placing aluminum or an aluminum alloy as an anode in an electrolyte containing hydrochloric acid, sulfuric acid, phosphoric acid, and an etching inhibitor for DC electrochemical etching, where the concentration of hydrochloric acid is 1.5 to 3 mol / L, the concentration of sulfuric acid is 0.9 to 1.2 mol / L, and the concentration of phosphoric acid is 0.6 to 1 mol / L. A method for integrating aluminum or an aluminum alloy and a plastic includes the following steps: forming a micro-nano porous structure on an aluminum or aluminum alloy surface by using the micro-nano processing method; and closely combining a plastic and the aluminum or aluminum alloy surface by means of the micro-nano porous structure. An aluminum or aluminum alloy structure has a micro-nano porous structure formed on the surface of the aluminum or aluminum alloy structure by using the micro-nano processing method. By using this method, the micro-nano hole processing efficiency is high, the quality is high, and the method is environmental friendly.

Description

technical field [0001] The invention relates to the technical field of aluminum or aluminum alloy surface processing, in particular to a micro-nano processing method for the surface of aluminum alloy, an integration method of aluminum or aluminum alloy and plastic, and an aluminum or aluminum alloy structure. Background technique [0002] Nano-molding technology is to use chemical or electrochemical means to erode the surface of the metal to form nano-holes. By selecting a special etching solution, the metal surface has a micro-nano porous structure similar to coral reefs. Then put the treated metal parts into the mold for in-mold injection molding, directly inject the plastic components onto the metal surface and solidify, and combine the plastic and the metal surface tightly through the mechanical locking effect of the micro-nano porous structure. Together. Finally, the injection molded part taken out of the mold can be subjected to all finishing processes on the metal su...
