Abstract
A color-zinc-plated sintered nd-fe-b magnet comprises a magnet base body which is made of sintered nd-fe-b magnetic materials. A layer of phosphate film is coated outside the magnet base body, and a protective layer is further coated outside the phosphate film. The protective layer is a color-zinc-plated layer. The color-zinc-plated sintered nd-fe-b magnet has the advantages that due to the fact that the magnet base body is made of the sintered nd-fe-b magnetic materials, and thus the color-zinc-plated sintered nd-fe-b magnet has an extremely high magnetic property and a good machining property and is stable in magnetic property. Simultaneously, the phosphate film is evenly coated on a magnet base body surface to enable the magnet base body surface to be stabilized and enable the color-zinc-plated sintered nd-fe-b magnet to have an extremely high weather-proof property. The color-zinc-plated layer is further coated outside the phosphate film, and thus the color-zinc-plated sintered nd-fe-b magnet has extremely high corrosion resistance and is free from being corroded even in hot and humid environment, thereby being enabled to be used in severe environment.
Description
Technical field
The utility model relates to a kind of magnet, relates in particular to a kind of zinc electroplating with iridescent yellow chromate conversion coating Sintered NdFeB magnet.
Background technology
Existing magnet does not have protective layer outward, usually exposes in a humid environment, and magnet is easy to be corroded, and rust staining often occurs, thereby affects magnet performance.
Summary of the invention
Have above-mentioned deficiency in the prior art in order to overcome, the utility model provide a kind of simple in structure, be difficult for being corroded, zinc electroplating with iridescent yellow chromate conversion coating Sintered NdFeB magnet that performance is good.
The technical scheme in the invention for solving the technical problem is: a kind of zinc electroplating with iridescent yellow chromate conversion coating Sintered NdFeB magnet; comprise the magnet matrix; described magnet matrix is that sintered Nd-Fe-B magnetic material is made; described magnet matrix is coated with one deck phosphate layer; this phosphate layer also is coated with layer protective layer outward, and this protective layer is color zinc coating.
The beneficial effects of the utility model are: because the magnet matrix is that sintered Nd-Fe-B magnetic material is made, especially adopting performance to add the HCJ sum greater than N48 and magnetic energy product makes greater than 60 sintered Nd-Fe-B magnetic material, thereby have high magnetic property, its maximum magnetic energy product exceeds ferrite more than 10 times, the machining property of itself is fairly good, can be processed into the various shapes that the client needs, such as: disk magnet, ring magnet, rectangular magnets, arc magnet and other various special-shaped magnets; And working temperature reaches as high as 200 degrees centigrade, and its quality is hard, and stable performance has good cost performance, can be widely used in motor, instrument and instrument, auto industry, petrochemical industry industry and the magnetic medical and health-care products etc.Phosphate layer is coated on equably the magnet matrix surface and makes its stabilisation, so that the utlity model has high weather-resistant property, phosphate layer also has the color zinc coating of one deck outward, thereby has high decay resistance, even under the environment of high temperature humidity, can not be corroded yet, thereby so that the utility model can be used in the adverse circumstances; And when color zinc coating was scratched, in humid air, near the color zinc coating the scratch position can be repaired the scratch position, thereby guarantees of the present utility model complete; Color zinc coating can make the utility model produce colored speckle simultaneously, so that the utility model is more attractive in appearance.
Description of drawings
Fig. 1 is schematic cross-section of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
With reference to Fig. 1, a kind of zinc electroplating with iridescent yellow chromate conversion coating Sintered NdFeB magnet comprises magnet matrix 1; described magnet matrix 1 is made for sintered Nd-Fe-B magnetic material; described magnet matrix 1 is coated with one deck phosphate layer 2, also is coated with layer protective layer 3 outside this phosphate layer 2, and this protective layer 3 is color zinc coating.
Because magnet matrix 1 is made for sintered Nd-Fe-B magnetic material, especially adopting performance to add the HCJ sum greater than N48 and magnetic energy product makes greater than 60 sintered Nd-Fe-B magnetic material, thereby have high magnetic property, its maximum magnetic energy product exceeds ferrite more than 10 times, the machining property of itself is fairly good, can be processed into the various shapes that the client needs, such as: disk magnet, ring magnet, rectangular magnets, arc magnet and other various special-shaped magnets; And working temperature reaches as high as 200 degrees centigrade, and its quality is hard, and stable performance has good cost performance, can be widely used in motor, instrument and instrument, auto industry, petrochemical industry industry and the magnetic medical and health-care products etc.Because phosphate layer 2 is coated on equably magnet matrix 1 surface and makes its stabilisation, so that the utlity model has high weather-resistant property, the color zinc coating of phosphate layer 2 outer in addition one decks, thereby has high decay resistance, even under the environment of high temperature humidity, can not be corroded yet, thereby so that the utility model can be used in the adverse circumstances; And when color zinc coating was scratched, in humid air, near the color zinc coating the scratch position can be repaired the scratch position, thereby guarantees of the present utility model complete; Color zinc coating can make the utility model produce colored speckle simultaneously, so that the utility model is more attractive in appearance.
Claims (1)
1. zinc electroplating with iridescent yellow chromate conversion coating Sintered NdFeB magnet; comprise the magnet matrix, it is characterized in that: described magnet matrix is that sintered Nd-Fe-B magnetic material is made, and described magnet matrix is coated with one deck phosphate layer; this phosphate layer also is coated with layer protective layer outward, and this protective layer is color zinc coating.
