Abstract
A kind of oil injector body of the application has Aluminum Coating on the oil injector body surface.The Aluminum Coating is to be sprayed at what oil injector body surface was formed by the way that the zinc-aluminium thin slice after fragmentation is placed in diluent, and wearing layer can also be further added by oil injector body surface.Oil injector body is protected through the above way, is got rusty easily after solving the problems, such as oil injector body long-time use.
Description
Technical field
The application is in relation to a kind of oil injector body and fuel injector, especially in relation to a kind of preferable fuel injector of surface rust-proof effect
Body and its fuel injector.
Background technology
In fuel combustion vehicle field, fuel injector is the important component that the fuel oil after pressurization is sprayed into combustion chamber.In fuel injector,
Oil injector body is made as its critical piece of alloy steel products.In long-term use, oil injector body and the nut on top by
It is outer in being exposed to, it inevitably contacts water or other impurity, surface gets rusty easily, influence the aesthetics on surface and partial
Energy.Cause main engine plants and the serious complaint of terminal user.
Oil injector body surface oxidisation in order to prevent, there are many surface treatment modes in the prior art.A kind of traditional processing
Mode is phosphatization, and phosphatization (phosphating) is the process that a kind of chemistry forms phosphate chemical conversion film with electrochemical reaction,
The phosphate conversion film formed is referred to as phosphating coat.Protection can be provided to parent metal, prevent metal to a certain extent
It is corroded；For preceding bottoming of painting, the adhesive force and anti-corrosion capability of paint film layer are improved；Antifriction is played in metal cold machining process
The effect of lubrication.
Another way is silanization, and silanization treatment has the advantages that following multiple compared with conventional phosphatizing：Without harmful weight
Metal ion, it is not phosphorous.Silane treatment process does not generate sediment, processing time is short, control simplicity.Processing step is few, can save
Table tune process, tank liquor are reusable.It can a variety of base materials such as collineation processing iron plate, galvanized sheet, aluminium sheet.
Above two processing mode needs some the component of antirust can generate positive effect in a short time.However, it
Equally exist some insurmountable problems, the anticorrosion time is short.And for fuel injector, it needs to be chronically exposed to sky
In gas, usage time is long, and use environment is typically in outdoor, and the possibility for contacting water and vapor is also relatively large.In addition,
To oil injector body, the intensity of this high voltage parts has extreme influence for pickling in the electroplating technologies such as phosphatization, can increase product fatigue
The risk of cracking.Therefore, it is necessary to antirust treatment is carried out by the way of special to oil injector body.
Utility model content
The application's is designed to provide a kind of oil injector body and fuel injector that can prevent from getting rusty for a long time.
The application provides a kind of oil injector body, has Aluminum Coating on the oil injector body surface.
Preferably, the Aluminum Coating is sprayed at oil injector body by the zinc thin slice and aluminum slice being mixed in chemical dilution agent
Surface is formed.
Preferably, the chemical dilution agent adds the mixed liquor of hydrogen light fraction and n-butanol for oil.
Preferably, the thickness of the Aluminum Coating is 6-16 μm.
Preferably, there is roughened layer between the Aluminum Coating and the spray apparatus surface.
Preferably, the roughening layer thickness is less than 1 μm.
Preferably, there is wearing layer outside the Aluminum Coating.
Preferably, the wear-resisting layer thickness is 1-5 μm.
The application also provides a kind of fuel injector, and the fuel injector includes oil injector body as described above.
Preferably, the fuel injector further includes nut, and the nut surface has Aluminum Coating.
Oil injector body used herein effectively can prevent oil injector body from giving birth to for a long time using Aluminum Coating technique
Rust.The Fatigue Strength Effect that similar plating pickling is avoided to bring simultaneously.
Description of the drawings
The exemplary embodiment of the application is described in detail below with reference to the accompanying drawings, it should be understood that described below
Embodiment is only used for explaining the application, and without being restricted to scope of the present application, appended attached drawing is wherein：
Fig. 1 is the structure chart of the application oil injector body one embodiment.
Fig. 2 is the structure diagram of the surface spraying layer of the application oil injector body one embodiment.
Specific embodiment
In different drawings, the same or similar component is presented with like reference characters.
It should be appreciated that attached drawing is only used for illustrating the application, the wherein size of component, proportionate relationship and component
Number is not as the limitation to the application.
Please refer to Fig.1 and Fig. 2 shown in, the structure diagram of the utility model one embodiment.Oil injector body 10 is generally
Approximate cylindrical, but have multiple steps above.It is generally made in oil injector body 10 of steel alloy, in the utility model,
The surface of oil injector body 10 forms a roughened layer 12 for being less than 1 μm by roughening treatment.The effect of roughened layer is increase oil spout
The roughness on 10 surface of body so as to increase the adhesive force of coating thereon, while can also make the surface color of roughened layer
It is beautiful again.In other embodiments, roughened layer 12 can be omitted.On roughened layer 12, there is Aluminum Coating 11, which applies
Layer 11 is usually used mixes minimum zinc-aluminium thin slice in chemical dilution agent, is then sprayed at fuel injector using the method for injection
10 surface of body is formed.In the present embodiment, the ingredient of chemical dilution agent adds the mixed liquor of hydrogen light fraction and n-butanol for oil,
After spraying, zinc metal sheet and the molding of aluminium flake interval are dispersed throughout 10 surface of oil injector body, form that multilayer zinc metal sheet interlocks with aluminium flake one every
Tomography prevents oxygen or water from being contacted with oil injector body 10, thus steel do not allow it is oxidizable.In addition, the because chemical property of zinc-aluminium
It enlivens than iron, even if fraction of air contacts, is also reacted first with zinc-aluminium, without being reacted with iron.Moreover, even if in zinc-aluminium
The surface of coating, which generates, to be scraped, and the zinc at scratch after contacting with the air, forms zinc oxide, and zinc oxide can be covered at former scratch,
There is self-regeneration.Usually, the thickness of Aluminum Coating is at 6-16 μm.
In order to protect Aluminum Coating 11, outside Aluminum Coating 11, one layer of wearing layer 13, the wearing layer 13 can be further added by
It is formed by spraying, to increase surface abrasion resistance and corrosion resistance.Usually, the thickness of the wearing layer 13 is 1-5um, is acted on
It is to prevent from wearing and hit, improves its case hardness, one layer of protection is further added by for Aluminum Coating 11.Certainly, other real
It applies in example, the wearing layer 13 can be omitted.
The utility model further includes a kind of fuel injector with above-mentioned oil injector body 10, and one is provided with above oil injector body
Coupling nut, the nut can also equally be handled using aforesaid way, also can effectively prevent the risk of getting rusty of nut in this way.
The application is described only in conjunction with the most practical preferred embodiment being presently considered above, it is to be understood that
Above description is not the limitation to the application, and the application is also not limited to the example above, the ordinary skill people of the art
The variations, modifications, additions or substitutions that member is made in the essential scope of the application should also belong to the protection domain of the application.
