Abstract
The invention relates to an anti-corrosion treatment method for neodymium iron boron ferrite. The anti-corrosion treatment method comprises the following steps: pretreatment: removing oil from the neodymium iron boron ferrite, and performing bright dipping, bleaching, activating, re-bleaching and the like in order to keep the outer surface of the neodymium iron boron ferrite clean and smooth; injecting tin and an anti-corrosion material into the surface of the neodymium iron boron ferrite by an iron injection way; forming a metal oxide layer or a clad layer or an anti-corrosion layer on the surface of the neodymium iron boron ferrite.
Description
Technical field
The invention belongs to the technical field of surface of magnetic material, particularly relates 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 affects 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 high harm of intractability of this kind of waste water is big.Using power consumption during 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 antiseptic new method of new neodymium iron boron ferrite, the method was being produced
Produce without substantial amounts of sewage in journey, and power consumption is little compared with plating.
The present invention is achieved by the following technical solutions：
Neodymium iron boron ferrite corrosion-resistant processing method, it is pre-treatment that its step is first, and neodymium iron boron ferrite is removed
Oil, goes out light, rinsing, activation, then rinses etc. and to process, to ensure that the outer surface of neodymium iron boron ferrite is cleaned and smooth.
Next to that first injecting tin using ion implanting mode on neodymium iron boron ferrite surface and then reinjecting anti-corrosion material；So
Form metal oxide layer or coating or anticorrosive coat on neodymium iron boron ferrite surface afterwards.
Described anti-corrosion material is metallic nickel.
The ion implanting energy is 42-45KeV magnitudes；
The network layers thickness altogether is 15-40nm.
The injection rate of the tin is 10mg/cm2-20mg/cm2, the injection rate of nickel be 25mg/cm2-40mg/cm2。
Technical solution of the present invention beneficial effect compared with the existing technology is：
By present treatment technique, by portion in the surface body that anticorrosive is directly penetrated into neodymium iron boron ferrite, anti-corrosion
Layer will not fall off, and add other anticorrosion modes, hence it is evident that improves the decay resistance of neodymium iron boron ferrite, and was producing
Journey environmental pollution is little, 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, to the base substrate of neodymium iron boron ferrite pre-treatment is carried out, and neodymium iron boron ferrite is carried out into oil removing, goes out light, is rinsed, is activated,
Rinse again etc. and to process, to ensure that the outer surface of neodymium iron boron ferrite is cleaned and smooth.
Next to that first injecting tin using ion implanting mode on neodymium iron boron ferrite surface and then reinjecting anti-corrosion material；So
Form metal oxide layer or coating or anticorrosive coat on neodymium iron boron ferrite surface afterwards.
Described anti-corrosion material is metallic nickel.
The ion implanting energy is 42-45KeV magnitudes..
The network layers thickness altogether is 15-40nm.
The injection rate of the tin is 10mg/cm2-20mg/cm2, the injection rate of nickel be 25mg/cm2-40mg/cm2。
The ion implanting energy of the present invention is 42-45KeV magnitudes；The selection of concrete Implantation Energy is according to material
Purposes or determination injection thickness selecting, the thickness that amorphous substance is injected in the present invention is 15-40nm, works 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 for injecting also accordingly is 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.
