Abstract

The invention provides a novel aluminum metal surface treatment method and an aluminum metal shell. The treatment method adopts the steps of degreasing, alkali etching, ash removal, anodic oxidation and N treatment to treat the aluminum metal surface. In the step, using N1 agent, N2 agent, N3 agent, N4 agent and N5 agent in order to perform N treatment on the surface of the aluminum metal that has been anodized, the aluminum metal shell includes an aluminum base, and is arranged on the aluminum The barrier layer on the surface of the substrate and the oxide film layer arranged on the surface of the barrier layer, the oxide film layer contains nanopores. Compared with the related art, the aluminum metal surface treated by the aluminum metal surface treatment method provided by the present invention has uniform nanopore size, good gloss, high-quality oxide film, and simple process steps.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of metal surface treatment, in particular to an aluminum metal surface treatment method and an aluminum metal shell. [0003] 【Background technique】 [0004] In the fields of automobiles, household electrical appliances, industrial machinery, etc., it is necessary to firmly combine metal and resin. At present, the common technology uses adhesives to function at room temperature or under heating to integrate metal and synthetic resin. . Directly integrating high-strength engineering resins with ferroalloys such as magnesium, aluminum alloys, and stainless steel without adhesives has become a research direction. [0005] Nano Machining Technology (NMT) is the integrated combination technology of metal and plastic. By nano-processing the surface of aluminum metal, plastic can be directly injection-molded on the surface of aluminum metal, so as to obtain metal-plastic integrated molding products. For t...
