Abstract
The invention discloses a neodymium-iron-boron magnet. The neodymium-iron-boron magnet comprises a neodymium-iron-boron base body and an alloy plating layer, wherein the alloy plating layer is electroplated on the surface of the neodymium-iron-boron base body; the alloy plating layer comprises a first plating layer and a second plating layer from inside to outside, wherein the first plating layer is an Ni-Cu-Ni layer, and the second plating layer is an Sn layer. The alloy plating layer of the neodymium-iron-boron magnet is low in porosity, and the salt fog resistance, the oxidative resistance, the corrosion resistance and the durability are all improved; the neodymium-iron-boron magnet is also excellent in the welding function; and the surface of the neodymium-iron-boron magnet is smooth without being contaminated by dust, and is non-reflective, so that the overall texture of the neodymium-iron-boron magnet is enhanced.
Description
Technical field
The present invention relates to a kind of magnetic material, particularly a kind of neodymium iron boron magnetic body.
Background technology
Neodymium-iron-boron magnetic material is as a kind of permanent magnetic material of extrahigh energy density, be widely used in every field, as electric motor car, wind power generation, nulcear magnetic resonance (NMR), industrial magneto, electronic equipment, magnetic machinery etc., the application of neodymium-iron-boron magnetic material in recent years achieves the development of advancing by leaps and bounds.
But existing neodymium-iron-boron magnetic material is easy to be corroded by oxygen in air and acid solution, in order to make it durable in use, or surface treatment method must be taked to make it to be improved, just the requirement of practical application can be reached by its chemical composition of adjustment.At present, neodymium-iron-boron magnetic material manufacturing industry generally adopts plated metal, plating adds the methods such as chemical plating metal, electrophoretic coating and phosphorating treatment and carries out surface treatment to it, even if but after these process, the salt fog resistance performance of neodymium-iron-boron magnetic material is not very strong, make it cannot be applied to extreme corrosion operational environment, such as offshore wind farm, deep submersible pump field etc.
The information being disclosed in this background technology part is only intended to increase the understanding to general background of the present invention, and should not be regarded as admitting or imply in any form that this information structure has been prior art that persons skilled in the art are known.
Summary of the invention
An object of the present invention is to provide a kind of neodymium iron boron magnetic body, thus overcomes the shortcoming of neodymium iron boron magnetic body salt fog resistance poor performance of the prior art.
For achieving the above object, the invention provides a kind of neodymium iron boron magnetic body, it comprises: neodymium iron boron matrix, and alloy layer, and its plating is on the surface of neodymium iron boron matrix, and alloy layer comprises from the inside to the outside: the first coating, and it is Ni-Cu-Ni layer; And second coating, it is Sn layer.
Preferably, in technique scheme, the thickness of the first coating is 8 ~ 15 μm, and the thickness of the second coating is 2 ~ 5 μm.
Compared with prior art, the present invention has following beneficial effect:
1. the alloy layer porosity of neodymium iron boron magnetic body of the present invention is little, and resistance to saltfog, oxidative resistance, corrosion resistance and resistance to wear all increase.
2. neodymium iron boron magnetic body of the present invention also has excellent welding function.
3. the surface of neodymium iron boron magnetic body of the present invention have smoothly, not easily covered with dust and opaque feature, therefore its overall texture strengthens.
Accompanying drawing explanation
Fig. 1 is the structural representation according to neodymium iron boron magnetic body of the present invention.
Main Reference Numerals illustrates:
1-neodymium iron boron magnetic body, 11-neodymium iron boron matrix, 12-alloy layer, 121-first coating, 122-second coating.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention not by the restriction of embodiment.
Clearly represent unless otherwise other, otherwise in whole specification and claims, term " comprise " or its conversion as " comprising " or " including " etc. by be understood to include the element of stating or part, and do not get rid of other elements or other parts.
As shown in Figure 1, according to a kind of neodymium iron boron magnetic body 1 of the specific embodiment of the invention, it comprises: neodymium iron boron matrix 11 and alloy layer 12.The surface at neodymium iron boron matrix 11 electroplated by alloy layer 12.Alloy layer comprises from the inside to the outside: the first coating 121 and the second coating 122.Wherein the first coating 121 is Ni-Cu-Ni layer, and the second coating 122 is Sn layer.
Preferably, in above-mentioned execution mode, the thickness of the first coating is 8 ~ 15 μm, and the thickness of the second coating is 2 ~ 5 μm.It is to be understood that those skilled in the art can select the thickness of the first coating and the second coating according to actual needs, and the present invention is not as limit.
The present invention is by alloy-layer on the plated surface of neodymium iron boron matrix, and make the porosity of neodymium iron boron magnetic body little, resistance to saltfog, oxidative resistance, corrosion resistance and resistance to wear all increase.The salt mist test of neodymium-iron-boron external surface of the present invention can reach more than 2000 hours, and has excellent welding function.In addition, alloy layer internal stress of the present invention is little, solution dispersibility and covering power good, current efficiency is high, neodymium iron boron magnetic body of the present invention is had smoothly, not easily covered with dust and opaque feature, therefore, while product decay resistance is largely increased, its texture is also enhanced.
The aforementioned description to concrete exemplary of the present invention is to illustrate and the object of illustration.These descriptions not want the present invention to be defined as disclosed precise forms, and obviously, according to above-mentioned instruction, can much change and change.The object selected exemplary embodiment and describe is to explain certain principles of the present invention and practical application thereof, thus those skilled in the art can be realized and utilize various different exemplary of the present invention and various different selection and change.Scope of the present invention is intended to limited by claims and equivalents thereof.
