Embodiment Construction

[0030] The invention discloses a treatment process for realizing a colorful effect on the surface of an aluminum alloy part, which includes the following steps:

[0031] (1) Pearl chrome is electroplated on the surface of the aluminum alloy part 10 .

[0032] (2) Pre-cleaning the aluminum alloy part 10 after electroplating with pearl chrome. Specifically, pre-cleaning includes the following steps:

[0033] 1) Ultrasonic degreasing: use metal degreasing powder, the concentration is 8-10%, the temperature is controlled at 80-90°C, and the time is 2-3 minutes;

[0034] 2) The first water washing: use clean water, the pH is 7.5, the temperature is controlled at 20-40°C, and the time is 3-4 minutes;

[0035] 3) Ultrasonic wax removal: use metal wax remover, the concentration is 8-10%, the temperature is controlled at 80-90°C, and the time is 2-3 minutes;

[0036] 4) The second water washing: use clean water, the pH is 7.5, the temperature is controlled at 20-40°C, and the time i...

Abstract

The invention discloses a treatment technology for realizing a colorful effect on the surface of an aluminum alloy part. The treatment technology comprises the following steps: (1) carrying out waterelectroplating on the surface of the aluminum alloy part through pearl chrome; (2) carrying out pre-washing on the aluminum alloy part subjected to the water electroplating of the pearl chrome; (3) carrying out surface film plating on the surface of the pearl chrome: selecting a zirconium target and a titanium target as target materials and controlling the furnace temperature to 90 to 100 DEG C, wherein step (3) comprises the following steps: 1) carrying out glow washing; 2) carrying out current bombardment; 3) plating; 4) depositing. According to the treatment technology disclosed by the invention, the pearl chrome is attached on the surface of the aluminum alloy part through the water electroplating; then the specific vacuum film plating is carried out after the pre-washing is carried out, so that a colorful film plating effect is directly realized on the surface of the aluminum alloy part and the coloring effect is good; a product has a more beautiful appearance and the requirementson utilization are met.

Description

technical field [0001] The invention relates to the technology in the field of hardware processing, in particular to a processing technology for realizing colorful effects on the surface of aluminum alloy parts. Background technique [0002] At present, the coloring of aluminum alloy products on the market is separately separated from vacuum plating coloring and spraying, painting or room temperature immersion coloring. The color effects of different coloring methods are not well combined. The appearance of aluminum alloy products is relatively simple, and the coloring effect is average, especially the colorful effect cannot be achieved, which also makes the application of aluminum alloy products have certain limitations. Therefore, it is necessary to make further improvements. Contents of the invention [0003] In view of this, the present invention aims at the deficiencies in the prior art, and its main purpose is to provide a treatment process for achieving a colorful ...
