Abstract
The invention relates to an engine surface anti-corrosion treatment method. The method comprises the following steps: 1) adopting ion implantation to implant an amorphous substance on the aluminum alloy surface of an engine and form an insoluble co-complexation layer; and 2) forming a metal oxide layer on the aluminum alloy surface of the engine, wherein the amorphous substance contains an organic compound or inorganic oxide.
Description
Technical field
The invention belongs to technical field of surface, refer to especially a kind of aluminium alloy engine surface anticorrosive treatment process.
Background technology
Metallic corrosion spreads all over national economy and national defense construction every field, endangers very serious.At first, corrosion can cause great direct or indirect financial loss.According to the statistics of the flourishing country of industry, the financial loss that causes because of corrosion accounts for the 1.5%-4.2% of then national economy total output value.Secondly, metallic corrosion, particularly stress corrosion and corrosion fatigue tend to cause calamitous Serious Accident, jeopardize personnel safety.Moreover, corrode a large amount of metals of not only loss, and wasted mass energy, the annual metal of wanting loss 10%-20% because of corrosion.In addition, in the industrial production such as oil, chemical industry, agricultural chemicals, because of the equipment run, drip, leak that corrosion causes, not only economic loss also may make toxic substance leak, and causes environmental pollution, jeopardizes people ' s health.Simultaneously, corrosion also may become the obstacle of production development and scientific-technical progress.
Existing automobile or ship engine are basically take aluminium alloy as main, and the corrosion that aluminium alloy occurs under various environmental activities can affect the performance of engine.For the generation that prevents from corroding, existing had multiple technologies to be used for preventing the generation of corroding.Wherein main aseptic technic is to adopt oxide film technology, antifouling paste technology and inhibiter technology.
In the guard technology of various metallic corrosion, the inhibiter technology is simple owing to technique, suitability becomes by force one of effective and the most the most frequently used method.But the inhibiter technology has obvious limitation, and in the liquid phase medium that inhibiter is most widely used, inhibiter must have certain solubleness, and must reach certain concentration.Traditional inhibiter has caused pollution because toxicity is larger to environment; Simultaneously, because the inhibiter consumption is less, extraneous small variation will cause larger impact to system, and this has brought very large difficulty also for the research of inhibition mechanism, these effects limit further developing of inhibiter.
Summary of the invention
The purpose of this invention is to provide a kind of new technical scheme, can be so that when not increasing metal thickness, improve the anticorrosion ability of engine by this technical scheme.
The present invention is achieved by the following technical solutions:
A kind of engine anti-corrosive treatment method, its step are at first to adopt ion implantation mode to inject amorphous substance to form insoluble altogether network layer on the engine aluminum alloy surface; Then the aluminum alloy surface at engine forms metal oxide layer.
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, condensed ring, conjugation heterocyclic compound, silicon-dioxide and Sodium Silicofluoride.
Described ion implantation be the 42-45KeV magnitude with energy;
Described altogether network layer thickness is 25-45nm.
Described injection rate is 45-50mg/cm
2
The beneficial effect that the present invention compares with prior art is:
By adopting ion implantation technique, amorphous substance injected form insoluble anti-corrosion layer in the metallic object, and this one deck is structure as a whole with metal, the problem that comes off in the existing aseptic technic can not appear, outmost amount at metal when ion implantation is lower than inner amount, do not affect such as the generation of oxide film and the application of other aseptic technic, improve the corrosion resistance nature of engine aluminum alloy.
Embodiment
The following specifically describes embodiments of the present invention.
The blank by each parts of prior art processing engine at first carries out removing surface with the aluminum alloy materials of each parts, chooses the amorphous substance for ion implantation usefulness, and described amorphous substance includes organic compound or inorganic oxide.Described amorphous substance includes zirconium phosphate, chromic acid chromium, condensed ring, contains the combination of one or both materials such as sulfenyl heterocyclic compound, silicon-dioxide and Sodium Silicofluoride.The amorphous substance of selecting in embodiments of the invention 1-6 has only been selected the amorphous substance of one-component, specifically sees Table 1.But usually do not do because of the toxic of chromic acid chromium and to select.
Of the present invention described ion implantation be the 42-45KeV magnitude with energy; Concrete selecting of Implantation Energy is to select according to the purposes of material or definite injection thickness, the thickness that injects in the present invention amorphous substance is 25-45nm, select the thickness that injects low when abominable or calling hierarchy is not high when the environment of materials'use, the also corresponding reduction of energy of therefore injecting usefulness; Abominable when the environment of materials'use, the thickness of injection is thick, the also corresponding raising of energy of therefore injecting.Described injection rate is 45-50mg/cm
2, employed Implantation Energy, injection thickness and unit consumption all are not quantitatively final in the present invention, just relatively good data can be adjusted according to actual needs, may reach the above magnitude of 120KeV such as Implantation Energy; Inject thickness and also may reach 75nm; Unit injects consumption also may reach 80mg/cm
2But the desired minimum data of this patent is master data, if be lower than minimum data then Corrosion Protection can't reach best.
Above specific embodiment only can be as reference of the present invention rather than limitation of the present invention.
Owing to the present invention relates to anti-corrosion layer, the therefore salt mist experiment below implementing, and determining the corrosion area width found after long-time through certain, to make erosion resistance evaluation substantially.
1), salt mist experiment
The spray chamber, concentration is about 5% NaCL solution, pressure is 60-180 kPa pressurized air, temperature can be remained on 87 ± 1 ℃ temperature regulator, be 95%-98% in relative humidity, temperature is that it is specific long-time to spray salt solution to each sample under 87 ± 1 ℃ the condition.
2), sample
Prepare in the following manner each engine blank sample, in parts such as the body of engine 1/4 ratio cast engine and cylinder caps, and the aluminium alloy outside surface of these parts carried out ion implantation and carry out oxide film and process, and go out vestige with graduating with cutter thereon.Comparative Examples is that the Al alloy block that only carries out the same size of oxide film and japanning also goes out vestige with graduating with cutter thereon.
3), estimate
The employing visual type checks.
Table 1
Show by above experiment, by adopting ion implantation mode amorphous substance is injected into the aluminum alloy surface certain thickness, can effectively stop the generation of corrosion phenomenon.
