Abstract

The invention discloses a magnesium alloy oxidation coloring method and a product thereof. The magnesium alloy oxidation coloring method comprises the steps: (1) degreasing magnesium alloy; (2) carrying out acid pickling on the degreased magnesium alloy; (3) carrying out surface conditioning on the magnesium alloy subjected to acid pickling; (4) baking the magnesium alloy subjected to surface conditioning; (5) feeding the baked magnesium alloy; (6) carrying out electrolytic coloring on the fed magnesium alloy; and (7) baking the magnesium alloy subjected to electrolytic coloring. The product is produced by using the magnesium alloy oxidation coloring method. The magnesium alloy oxidation coloring is combined with formation pretreatment and is simple and convenient in operation process and good in effect, the defect of single color for surface treatment on magnesium alloy is overcome, the range of a requirement for the quality of the surface of a material is relatively wide, the corrosion resistance and wear resistance of the magnesium alloy are greatly improved by the surface appearance of a coloring sample, the coloring process is relatively environment-friendly, a great number of harmful substances cannot be produced in an oxidation reaction process, and therefore, the magnesium alloy oxidation coloring method is suitable for factory quantified production.

Description

Technical field

[0001] The invention relates to an oxidation color development method and a product thereof, in particular to a magnesium alloy oxidation color development method and a product thereof.

Background technique

[0002] Magnesium and magnesium alloys have low density, high specific strength, good chip processing performance and excellent electromagnetic shielding, and are widely used in transportation, aerospace, and 3C fields. However, due to its active chemical properties, the electrode potential is very low and easy to corrode, which limits its application. Magnesium and magnesium alloy surface treatment technology can not only improve the surface corrosion resistance and wear resistance, but also improve the appearance effect, prolong the service life and expand the application range.

[0003] The domestic South China University of Technology once used potassium permanganate as a colorant to produce a yellow ceramic film on the surface of magnesium alloy...
