Example Embodiment

[0030] The invention discloses a treatment process for realizing dazzling effects on the surface of aluminum alloy parts, including the following steps:

[0031] (1) Water-plated pearl chromium on the surface of aluminum alloy parts 10.

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

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

[0034] 2) The first washing: Use clean water, pH 7.5, temperature control at 20-40℃, time 3-4 minutes;

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

[0036] 4) The second water wash: use clean water, pH 7.5, temperature control at 20-40 ℃, time 3-4 minutes;

[0037] 5) The third water wash: use clean water, pH 7.5, temp

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.
