In the process, International Minerals in 1988 and chemical company for the first time using natural zeolite as corrosion-inhibiting coating filler (US4738720) into
Row exploitation use, 2001 tight Yushan et al. for the first time aluminum alloy surface growth in situ MFI zeolite coating and to its antiseptic property into
Row characterization (ELECTROCHEM SOLID ST.2001,4, B23-26), Dong Yanjuan in 2014 et al. are in situ after gel by first applying
The secondary synthesis technology of growth grows MFI zeolite coating (CN103818089 A) in 1060 aluminum alloy surfaces, the results showed that, aluminium
The high silicon MFI-type molecular screen membrane of alloy surface has good antiseptic property.However direct in-situ is grown at present or two is secondary
Long anti-corrosion MFI zeolite coating is not fine and close, and there is zeolite intergranular gaps, this is not to manage very much for anti-corrosion effect
Think.Anodizing technology is industrial more mature valve metal process for treating surface, and the technical matters is simple, can close in aluminium
Gold surface obtains the alumina layer of one layer of nano aperture.The alumina layer is coarse, surface can larger, good hydrophilic property, be used for
The growth substrate of zeolite membrane is easier to induce and promote the nucleation of zeolite crystal, and then is conducive to aluminum alloy surface densification anti-corrosion zeolite
The formation of film.
