Description
Technical field
The present invention relates to the technical field of diamond tool, it is more particularly related to a kind of hard emery wheel and its
Preparation method.
Background technology
Diamond-impregnated wheel is mainly used in the flat surface grinding working process of the materials such as marble, granite, cement concrete, main
Play grinding corner and surface action.Diamond-impregnated wheel generally uses structure of mounting hole, it is easy to load and unload, with processing flatness
Well, the features such as grinding efficiency is high, and a variety of equipment for grinding can be applied to.
Diamond-impregnated wheel is generally by integral heat pressure sinter molding, and its process characteristic is by metallic bond and Buddha's warrior attendant stone mill
Grain direct sintering is in steel matrix.Due to the linear expansion coefficient of steel matrix and metallic bond and diamond abrasive grain exist it is larger
Thermal stress can be produced after difference, sintering, so that the bond strength between diamond segment and steel matrix is relatively low, is easily caused
Shearing separation causes cutter head to occur improper destruction.Therefore, in the prior art by between diamond segment and matrix
One layer is set not include the basalis of diamond abrasive grain to improve bond strength therebetween, basalis is generally also by metal knot
Mixture is constituted, but its bond strength is still relatively low.In addition, prior art can also by soldering processes by diamond segment with
Matrix is combined, but for the preparation of the diamond-impregnated wheel of multi-knife-head, brazing operation technique is complicated, takes longer.
The content of the invention
In order to overcome the drawbacks described above that prior art is present, combined by force with steel matrix it is an object of the invention to provide one kind
High hard emery wheel of degree and preparation method thereof.
In order to realize foregoing invention purpose, the first aspect of the present invention employs following technical scheme：
A kind of hard emery wheel, it includes annular base, is characterised by the annular base being formed with by cold spraying and beats
Pass through hot pressed sintering formation abrasive material working lining on bottom abrasive material, the prime coat.
Wherein, the thickness of the bottoming abrasive material is 20 μm~200 μm, preferably 20~100 μm.
Wherein, the bottoming abrasive material is made up of metallic bond.
Wherein, the abrasive material working lining is made up of metallic bond and hard abrasive material.
Wherein, the bottoming abrasive material is identical with the metallic bond used in abrasive material working lining.
Wherein, the bottoming abrasive material is different with the metallic bond used in abrasive material working lining.
The second aspect of the present invention, further relates to a kind of preparation method of hard emery wheel, it includes annular base, and feature exists
In：Bottoming abrasive material is formed with by cold spraying on the annular base first, then passed through on the bottoming abrasive material
Hot pressed sintering formation abrasive material working lining.
Wherein, the bottoming abrasive material is made up of metallic bond.
Wherein, the abrasive material working lining is made up of metallic bond and hard abrasive material.
Wherein, the bottoming abrasive material is identical with the metallic bond used in abrasive material working lining.
Compared with immediate prior art, the hard emery wheel of the present invention for preparing has the advantages that：
The hard emery wheel of the present invention ensure that matrix is combined with abrasive material working lining with soldering by introducing cold spray process
The bond strength of suitable even more high, so that the hard emery wheel of the present invention can be applied to the environment of high-speed grinding.And
The abrasive material prime coat that cold spraying is formed can equally play ablation, reduce the waste of metallic bond.
Embodiment
Hard emery wheel of the present invention and preparation method thereof is further elaborated below with reference to specific embodiment,
To make more complete and clear explanation to technical scheme.
The present invention relates to a kind of hard emery wheel, it includes being formed with by cold spraying on annular base, the annular base
By hot pressed sintering formation abrasive material working lining on bottoming abrasive material, bottoming abrasive material, the thickness of the bottoming abrasive material for 100~
2000 μm, preferably 200~1000 μm.The bottoming abrasive material is made up of metallic bond, and abrasive material working lining is combined by metal
Agent and hard abrasive material composition.In the present invention, the bottoming abrasive material is different with the metallic bond used in abrasive material working lining,
For example bottoming abrasive material can be using having the metallic bond of more preferable bond strength with substrate, and the metal knot of abrasive material working lining
Mixture mainly considers the matching with hard abrasive material, for example, can have good hold to hard abrasive material and with described hard
The loss of matter abrasive material is suitable.Certainly, because cold spray process can accelerate metallic bond to critical speed by compressed air
So that metallic is attacked directly to after matrix surface physical deformation occurs for (supersonic speed), and metallic hits flat in matrix surface and firm
Attachment, and then eliminating distortional stress in abrasive material working lining hot pressed sintering further increases adhesiveness, so as to
Greatly improve the bond strength between abrasive material working lining and matrix.Therefore, in the present invention, the metal knot that bottoming abrasive material is used
Mixture is identical with the composition of the metallic bond of abrasive material working lining, also can guarantee that abrasive material working lining has with matrix and is combined with soldering
The bond strength of suitable even more high.The metallic bond be copper base metal bonding agent or ferrous metals bonding agent, and its
In can be added with Co, Ni, Sn, Zn, Si, B, Ti or Re (rare earth).As exemplarily, the metallic bond can for example be selected
FAM1021 alloyed powders (such as Ni containing 18.2wt%, 2.0wt% Co and the Fe of surplus electrolysis alloyed powder), LFP is selected to close
Bronze (such as Cu containing 15.0wt%, 3.8wt% Sn, 12.0wt% Ni, 1.8wt% Co and the Fe of surplus electrolysis
Powder), copper base metal bonding agent etc..The hard abrasive material includes diamond, carbide, boride, nitride, carbonitride or oxygen
Nitride, for example preferably, can select diamond, boron nitride, carborundum, silicon nitride, silica, titanium carbide, nitrogen
Change titanium, titanium dioxide etc..Wherein, most preferably diamond and/or boron nitride, and their particle diameter is generally 100~500
μm scope.
