Description
Technical field
Patent of the present invention is related to field of machining, especially a kind of compositive lining Buddha's warrior attendant stone mill for iron-binding agent
Grain.
Background technology
Diamond with exceptional hardness, superelevation thermal conductivity is the preferable abrasive material for processing of stone, geological prospecting etc..But by
Have between the diamond with covalent bond structure and in general metal very high interface can, therefore, common metal bonding agent with
More difficult formation chemical bond between diamond abrasive, but based on mechanism tessellation, make bonding agent to diamond without foot
Enough holds, in use diamond abrasive grain easily come off, be lost in, not only shorten diamond tool use the longevity
Life, and influence processing efficiency.In diamond metalwork manufacture, because ferrous metals bonding agent can produce by force to diamond
Strong corrosion, at present metallic bond use iron-binding agent to substitute copper mainly using the higher copper-based or cobalt base bonding agent of cost
Base or cobalt-based metallic bond, there is positive effect by being reduced to the cost of diamond metalwork.Diamond surface plating energy
The interface cohesion being enough effectively improved between diamond and metallic bond, diamond is protected by ferrous metals bedroom, not use plating
It is to improve diamond sintering product properties, reduce the effective ways of cost to cover diamond abrasive grain.
The material of diamond surface plating can be metal, ceramics or multilayer materials, and these materials generally can be with
It is divided into three classes：One kind is graphite element, the Ferrious material element such as including Fe, Ni, Co, and these elements can make diamond in heat
Graphitization Eroded diamond occurs during pressure in advance, is unfavorable for the diamond of hot pressed sintering；Second class is carbide shape
Into element, mainly there are the transiting group metal elements such as Ti, V, Cr, Mo, Nb, W, these elements can under certain condition and diamond
The carbon atom on surface reacts to form carbide membrane so that coating can realize chemical bond with diamond, have preferable
Bond strength；3rd class is the not metallic element with diamond reaction and corresponding compound, such as the low melting point such as Cu, Sn, Zn
Element and the ceramic material such as alloy and aluminum oxide, silica.
At present both at home and abroad by using vacuum PVD technology, salt bath coating technology, powder covering sintering plating
The micro- evaporation technique of technology, electroless plating technology, electroplating technology, sol-gel technique, vacuum etc. is single in diamond surface plating
The composite deposite of coating or multilayer.The larger coating of usage amount is individual layer vanadium or individual layer nickel wherein in plating diamond, nickel coating
With good thermal conductivity, electric conductivity, thicker thickness can be accomplished, surface can make coarse structure, improve bonding agent pair
The mechanical hold of diamond, diamond abrasive grain profit on sales can be additionally improved, but can be to gold in high-temperature sintering process
Hard rock produces erosion, promotes its surface graphitization, declines tool performance, therefore nickel plating diamond is now widely used for resin
Bonding agent and plating metal bonding agent.Plating titanium layer can form chemical bond between diamond at high temperature, while can prevent
Only diamond surface is corroded by other elements, but coating is relatively thin, and not good enough to the binding ability of ferrous metals.
For as above problem, patent CN205258613 discloses a kind of iron-based matrix diamond composite structure, its structure
By up of three layers, the coating near diamond is tungsten coating, tungsten coating is outside cobalt coating, outermost layer is iron plating, this patent
Technology can avoid diamond from being corroded by iron-binding agent, make not produce sharp interface between diamond and each coating, carry
Hold of the high bonding agent to diamond.Patent CN1786274A discloses a kind of diamond surface titanium coating nickel coating copper coating composite junction
Structure and manufacture method, using the micro- evaporation of vacuum in ti coated diamond, pierced in the nickel plating of titanizing layer surface, nickel thorn surface chemistry
Copper facing, the method can improve the height of protrusion of diamond abrasive tool, increase the service life.But existing public technology is using process
In many deficiencies also be present, such as nickel thorn may disappear in high-temperature sintering process, make not clear to the lifting of diamond hold
Aobvious, titanium coating is excessively thin bad to diamond protecting effect etc., therefore can not all obtain good using effect.
The content of the invention
The purpose of the present invention is to improve existing diamond abrasive grain easily to be corroded by ferrous metals, and diamond abrasive grain surface light
Cunning causes the shortcomings that hold is poor, height of protrusion is low, there is provided a kind of compositive lining diamond abrasive grain for iron-binding agent.
Exemplified by realize above-mentioned purpose, the present invention is achieved by following technical solution.
A kind of compositive lining diamond abrasive grain for iron-binding agent, it is by diamond, carbonization vanadium layers, vanadium layers, nanometer
Silicon-carbide particle, nickel dam composition, it is characterised in that carbonization is formed between diamond surface plating vanadium layers, vanadium layers and diamond surface
Vanadium layers, vanadium coating outer surface plating are embedded with the nickel dam of silicon-carbide particle.Preferable diamond particles particle diameter is more than 40 μm, carbonization
For silicon grain particle diameter below 1 μm, coating gross thickness is 1-15 μm.
The beneficial effects of the invention are as follows：
1. nano silicon carbide granulate is dispersed in nickel coating, reduces the amount of the nickel contacted with vanadium coating or iron, improve coating
To the protective capability of diamond；
2. abrasive particle surface is coarse, hold of the bonding agent to abrasive particle is added；
3. nickel coating and vanadium coating and ferrous metals all have good binding ability, holding of the bonding agent to diamond is improved
Power；
4. a pair iron-binding agent has certain enhancing effect, the intensity of product can be improved.
