Problems solved by technology

However, corrosion inhibitor technology has obvious limitations. In the liquid medium where corrosion inhibitors are most widely used, corrosion inhibitors must have a certain solubility and must reach a certain concentration.
Traditional corrosion inhibitors have polluted the environment due to their high toxicity; at the same time, due to the small amount of corrosion inhibitors used, small changes in the outside world will have a greater impact on the system, which also brings new challenges to the study of corrosion inhibition mechanisms. These factors have limited the further development of corrosion inhibitors

Embodiment Construction

[0015] Embodiments of the present invention are specifically described below.

[0016] Firstly, take the metal aluminum plate, and you can also choose other types or shapes of aluminum materials according to the needs, clean the surface of the aluminum materials, and select amorphous substances for ion implantation, the amorphous substances include organic compounds, or Inorganic oxides. The amorphous substance includes one or a combination of zirconium phosphate, chromium chromate, monocyclic, condensed ring, sulfur-containing heterocyclic compounds, silicon dioxide and sodium fluorosilicate. The amorphous substances selected in Examples 1-6 of the present invention are only single-component amorphous substances, see Table 1 for details. However, due to the toxicity of chromium chromate, it is usually not used.

[0017] The ion implantation energy of the present invention is on the order of 45-80KeV; the specific implantation energy is selected according to the purpose of t...

Abstract

The present invention relates to an aluminum surface anti-corrosion treatment method, which comprises the following steps: injecting an amorphous material on the aluminum metal surface by using an ion injection manner to form an insoluble co-complex layer, then forming a metal oxidation layer on the metal surface, and coating a prime coat on the metal oxidation layer, wherein the amorphous material comprises an organic compound or an inorganic oxide.

Description

technical field [0001] The invention belongs to the field of new materials, in particular to a method for anticorrosion treatment of metal aluminum surfaces. Background technique [0002] Metal corrosion pervades all fields of national economy and national defense construction, and the harm is very serious. First, corrosion can cause significant direct or indirect economic losses. According to the statistics of industrially developed countries, the economic loss caused by corrosion accounts for about 1.5%-4.2% of the national economic output value of the year. Secondly, metal corrosion, especially stress corrosion and corrosion fatigue, often cause catastrophic major accidents and endanger personal safety. Furthermore, corrosion not only consumes a large amount of metal, but also wastes a large amount of energy, and 10%-20% of metal is lost due to corrosion every year. In addition, in the industrial production of petroleum, chemical industry, and pesticides, equipment run...
