Abstract
It is used for neodymium iron boron ferrite corrosion-resistant processing method the present invention relates to one kind, its step includes：First it is pre-treatment, neodymium iron boron ferrite is carried out into oil removing, light extraction, rinsing, activation, then the treatment such as rinse, cleaned and smooth with the outer surface for ensureing neodymium iron boron ferrite；Next to that injecting anti-corrosion material using ion implanting mode on neodymium iron boron ferrite surface；Then metal oxide layer or coating or anticorrosive coat are formed on neodymium iron boron ferrite surface.
Description
Technical field
The invention belongs to the technical field of surface of magnetic material, particularly relate to a kind of for neodymium iron boron ferrite anti-corrosion
Processing method.
Background technology
Neodymium iron boron ferrite as rare earth permanent-magnetic material, with excellent magnetic property, good machining characteristics and phase
To cheap price, it is widely used in fields such as automation, computer, household electrical appliances, communications.But neodymium iron boron ferrite material
Poor chemical stability, is easy to oxidation in use environment, and serious chemical attack can occur under wet heat condition, deteriorates magnetic
Performance simultaneously influences the service life of magnet.
The main method for solving neodymium iron boron ferrite etching problem at present is to deposit one layer of corrosion-resistant coating in magnet surface, main
The handling process wanted has the process of surface treatment such as galvanoplastic or chemical plating, but both techniques have obvious defect, be exactly
There is substantial amounts of waste water to produce in production process, and the intractability harm high of this kind of waste water is big.Power consumption during using plating
Greatly, it is unfavorable for energy-conservation, does not meet environmental protection and power conservation requirement.
The content of the invention
It is an object of the invention to provide a kind of new method of new neodymium iron boron ferrite preservative treatment, the method was being produced
There is no substantial amounts of sewage to produce in journey, and power consumption is small compared with plating.
The present invention is achieved by the following technical solutions：
One kind is used for neodymium iron boron ferrite corrosion-resistant processing method, and it is pre-treatment that its step is first, by neodymium iron boron iron oxygen
Body carries out oil removing, light extraction, rinsing, activation, then the treatment such as rinses, and is cleaned and smooth with the outer surface for ensureing neodymium iron boron ferrite.
Next to that injecting anti-corrosion material nickel borides using ion implanting mode on neodymium iron boron ferrite surface；Then in neodymium iron
Boron ferrite surfaces form metal oxide layer or coating or anticorrosive coat.
The ion implanting energy is 45-50KeV magnitudes；
The network layers thickness altogether is 5-40nm.
The injection rate is 20mg/cm2-40mg/cm2。
Technical solution of the present invention beneficial effect compared with the existing technology is：
By present treatment technique, by portion, anti-corrosion in the surface body that anticorrosive is directly penetrated into neodymium iron boron ferrite
Layer will not fall off, and add other anticorrosion modes, hence it is evident that improve the decay resistance of neodymium iron boron ferrite, and produce
Journey environmental pollution is small, meets national energy-saving environmental requirement.
Specific embodiment
The following specifically describes embodiments of the present invention.
The base substrate of neodymium iron boron ferrite is taken first, it is also possible to choose the neodymium iron boron iron oxygen of other models or shape as needed
Body material, the base substrate to neodymium iron boron ferrite carries out pre-treatment, and neodymium iron boron ferrite is carried out into oil removing, and light extraction is rinsed, activated,
The treatment such as rinse again, cleaned and smooth with the outer surface for ensureing neodymium iron boron ferrite.
Next to that injecting anti-corrosion material nickel borides using ion implanting mode on neodymium iron boron ferrite surface；Then in neodymium iron
Boron ferrite surfaces form metal oxide layer or coating or anticorrosive coat.
The ion implanting energy is 45-50KeV magnitudes；
The network layers thickness altogether is 5-40nm.
The injection rate is 20mg/cm2-40mg/cm2。
The ion implanting energy of the invention is 45-50KeV magnitudes；The selection of specific Implantation Energy is according to material
Purposes or the injection thickness of determination select, the thickness that amorphous substance is injected in the present invention is 5-40nm, work as material
The environment for using selects the thickness of injection low when severe or calling hierarchy is not high, therefore the energy of injection is also accordingly reduced；
When the bad environments of materials'use, the thickness of injection is thick, therefore the energy of injection is also accordingly improved.Used in the present invention
Implantation Energy, injection thickness and unit dose be not final quantitative, simply preferably data relatively, according to actual needs may be used
To be adjusted, such as Implantation Energy may reach 100KeV magnitudes even 120KeV magnitudes；Injection thickness is likely to meeting
Reach 75nm；Unit injection consumption is likely to that 80mg/cm can be reached2.But the minimum data required by this patent is master data,
Corrosion Protection is unable to reach most preferably if less than minimum data.
Specific embodiment above is only capable of as of the invention with reference to rather than limitation of the present invention.
