Abstract
The invention relates to an aluminum alloy anticorrosive treatment method. The method comprises the steps of first injecting non-crystalline substance into the surface of aluminum alloy in a mode of ion implantation to form an insoluble co-complexation layer; and then forming a metal oxide layer on the surface of the aluminum alloy, wherein the non-crystalline substance comprises an organic compound or an inorganic oxide.
Description
Technical field
The invention belongs to field of new, refer to a kind of Anti-corrosive treatment method for aluminum alloy especially.
Background technology
Metallic corrosion, throughout national economy and national defense construction every field, endangers very serious.First, corrosion can cause great direct or indirect financial loss.According to the statistics of the country of industry prosperity, account for the 1.5%-4.2% of national economy total output value then because corroding the financial loss caused.Secondly, metallic corrosion, particularly stress corrosion and corrosion fatigue, often cause calamitous Serious Accident, jeopardize personnel safety.Moreover, corrode a large amount of metal of not only loss, and waste mass energy, every year because the metal of loss 10%-20% is wanted in corrosion.In addition, in the industrial production such as oil, chemical industry, agricultural chemicals, because corroding the equipment run, drip, leak caused, not only causing financial loss, also may make hazardous material situations, causing environmental pollution, jeopardizing people ' s health.Meanwhile, corrosion also may become the obstacle of production development and scientific-technical progress.
The corrosion that aluminium alloy occurs under various environmental activity, throughout each department of national economy, brings about great losses.In order to prevent the generation of corroding, the existing generation having had multiple technologies to be used for preventing from corroding.Wherein main aseptic technic adopts oxide film technology, antifouling paste technology and inhibiter technology.
In the guard technology of various metallic corrosion, inhibiter technology because technique is simple, suitability is strong and become one of effective and the most the most frequently used method.But inhibiter technology has obvious limitation, in the liquid phase medium that inhibiter is most widely used, inhibiter must have certain solubleness, and must reach certain concentration.Traditional inhibiter is comparatively large due to toxicity, causes pollution to environment; Meanwhile, because inhibiter consumption is less, extraneous small change will cause larger impact to system, and this brings very large difficulty also to the research of inhibition mechanism, and these factors limit further developing of inhibiter.
Summary of the invention
The object of this invention is to provide a kind of new technical scheme, can make to improve anticorrosion ability while not increasing metal thickness by this technical scheme.
The present invention is achieved by the following technical solutions:
A kind of Anti-corrosive treatment method for aluminum alloy, its step first adopts ion implantation mode to inject amorphous substance in aluminum alloy surface to form insoluble network layers altogether; Secondly metal oxide layer is formed in aluminum alloy surface; Wherein ion implantation include first time ion implantation and second time ion implantation.
Described amorphous substance includes organic compound or inorganic oxide.
Described amorphous substance includes the combination of one or both materials such as zirconium phosphate, chromic acid chromium, monocycle, condensed ring, conjugation heterocyclic compound, silicon-dioxide and Sodium Silicofluoride.
Described first time, ion implantation energy was 60-80KeV magnitude; The ion implantation energy of described second time is 40-42KeV magnitude.
Described network layers thickness is altogether 10-40nm.
Described injection rate is 25mg/cm
2-40mg/cm
2.
The present invention's beneficial effect is compared with the existing technology:
By adopting ion implantation technique, amorphous substance is injected in metallic object, forms insoluble anti-corrosion layer, and this one deck is structure as a whole with metal, there will not be the problem that comes off in existing aseptic technic, in the amount of the outmost amount of metal lower than inside time ion implantation, do not affect the application of generation as oxide film and other aseptic technic, improve the corrosion resistance nature of aluminium alloy.
Embodiment
The following specifically describes embodiments of the present invention.
First aluminum alloy plate materials is got, also the aluminum alloy materials of other model or shape can be chosen as required, aluminum alloy materials is carried out removing surface, and choose for ion implantation amorphous substance, described amorphous substance includes organic compound or inorganic oxide.Described amorphous substance includes zirconium phosphate, chromic acid chromium, monocycle, condensed ring, combination containing one or both materials such as sulfenyl heterocyclic compound, silicon-dioxide and Sodium Silicofluorides.The amorphous substance selected in embodiments of the invention 1-6 has only selected the amorphous substance of one-component, but does not usually select because of the toxic of chromic acid chromium.
First time of the present invention, ion implantation energy was 60-80KeV magnitude; The ion implantation energy of second time is 40-42KeV magnitude.Selecting of concrete Implantation Energy is selected according to the purposes of material or the injection thickness determined, the thickness injecting amorphous substance is in the present invention 10-40nm, select the thickness that injects low when the environment of materials'use is severe or calling hierarchy is not high, the energy therefore injected is corresponding reduction also; When the bad environments of materials'use, the thickness of injection is thick, and the energy therefore injected is corresponding raising also.But the minimum data required by this patent is master data, if lower than minimum data, Corrosion Protection cannot reach best.
Above specific embodiment only can as reference of the present invention instead of limitation of the present invention.
Owing to the present invention relates to anti-corrosion layer, therefore by implementing salt mist experiment below, and after a fixed length time, determining found corrosion area width, to make erosion resistance evaluation substantially.
1), salt mist experiment
Spray chamber, concentration is the NaCL solution of about 5%, and pressure is the pressurized air of 60-180 kPa, temperature can be remained on the temperature regulator of 35 DEG C ± 1 DEG C, be 95%-98% in relative humidity, temperature is under the condition of 35 DEG C ± 1 DEG C, sprays salt solution for a long time specific to each sample.
2), sample
Prepare each block sample in the following manner, measure one block of aluminium alloy being of a size of 30mm × 100mm × 3mm and carry out ion implantation and carry out oxide film process, and go out vestige with graduating with cutter thereon.Comparative example is that the Al alloy block of the same size only carrying out oxide film and paint also goes out vestige with graduating with cutter thereon.
3), evaluate, adopt visual type inspection.
