Specific embodiment
The invention will be further elaborated with specific embodiment with reference to the accompanying drawing.
A kind of nonmagnetic metal ceramal, mix material proportioning mass parts and granularity are as follows:
Ball milling material: 58 parts of TiCN, 8 parts of Mo2C, 7 parts of Co, 8 parts of Ni, 5 parts of NbC, 1 part of VC, 0.18 part of ZrC, remaining
Amount is WC powder；
The Fisher particle size of TiCN is 1-3um；The Fisher particle size of Mo2C is 3-5um；The Fisher particle size of Co is 1-4um；Ni's
Fisher particle size is 1-3um；The Fisher particle size of NbC is 1-3um；The Fisher particle size of VC is 1-4um；The Fisher particle size of ZrC is 1-

Forming agent, dispersing agent: 2 parts of paraffin；0.1 part of oleic acid.
Ball-milling medium alcohol: every kilogram of ball milling material adds alcohol 660ml.
Ratio of grinding media to material: 4:1.
Product carburizing or decarburization defect are improved using the cermet of said ratio, because it is with nonmagnetic feature,
Enhance the corrosion resistance of Binder Phase Ni, Co and hard phase WC, and the crystal grain refinement of cermet.Cermet
Hardness, wearability and corrosion resistance be all improved.
A kind of nonmagnetic metal ceramal preparation method；
(1) ingredient, ball milling: according to the content of component of mixture by WC, TiCN, Mo2C, Co, Ni, NbC, VC, ZrC are former
Feed powder end puts into ball mill and carries out ball milling, and ball milling method is wet-milling, and Ball-milling Time 30-60 hours.
(2) spray-drying process: by the mixed slurry after ball milling by spray drying, sieving, epigranular is obtained, oxygen contains
Measure cermet mixture low, that water content is low.
(3) it forms: shape required for being obtained using the method for compression molding, isostatic pressing or extrusion forming, molding
Green compact has certain intensity.
(4) it is sintered: green compact after molding is sintered, burnt when solid solution is formed using the nitrogen atmosphere of 300-1000Pa
Knot；1450-1600 DEG C of sintering temperature, 60-90 minutes are kept the temperature, obtains fine and close cermet.
Lithium ion battery knife made of a kind of above-mentioned nonmagnetic metal ceramal, as shown in Figure 1, the non magnetic gold of the present invention
Section in blade cutting electrode paillon made of cermet, which refers to, does not generate wire drawing, flash, core exception, active matter
Abnormal, barbed, the tubaeform section of matter.
As shown in Fig. 2, the section in general blade cutting electrode paillon, takes place drawing from one layer of aluminium foil of middle
Silk and flash.
As shown in figure 3, there is core displacement, should normally hit exactly in the section in general blade cutting electrode paillon
Between aluminium foil be displaced to upside.
As shown in figure 4, core broken string, occurs in the section in general blade cutting electrode paillon, core midway is disconnected
As shown in figure 5, there is the removing of active material and falls off in the section in general blade cutting electrode paillon, it is living
There is peeling above property substance.
As shown in fig. 6, the section in general blade cutting electrode paillon, appearance is tubaeform, wavy above workpiece,
Occur when rolling bad.
It can be seen that general carbon nitridation titanium ceramet cutter, addition binding material assigns bending strength, toughness, resistance to
Mill property.But many binding materials are needed in order to improve mechanical property, so having to increase and the very high metal of aluminium compatibility
Material.Therefore, the carbon nitridation titanium ceramet generally occurred on the market has the tendency that aluminium attachment, by the comparison of Fig. 1-6,
The carbon nitridation titanium ceramet cutter now occurred in society at present is unsatisfactory for the condition of cutting electrode paillon.
We have carried out fine and close configuration to hard material, it are made hole do not occur reducing the dosage of binding material
Gap keeps the granularity and shape with bending strength and toughness hard phase.Also, the addition binding material is further prepared
Amount is minimized, can improve the metal material of toughness, has developed the novel carbon nitridation titanium ceramet of easily attachment aluminium.
