Description
Technical field
The invention belongs to technical field of material surface treatment, and in particular to the method for diamond particle surfaces salt bath titanizing.
Background technique
Diamond is the highest substance of hardness in nature, by by the metal based on diamond particles and Fe, Co, Cu etc.
Bonding agent is sintered, and is widely used in the diamond tool for preparing various cuttings, sawing and probing.On the other hand, due to
Diamond has high thermal conductivity, can by the way that the high-thermal conductive metals such as diamond particles and copper, aluminium, silver are constituted composite material
For use as the high efficiency and heat radiation component in the fields such as Electronic Packaging.
The preparation method of diamond tool is mainly powder metallurgic method, and sintering temperature is up to 800~900 DEG C, and (diamond exists
Graphitization tendency is obvious at 900 DEG C or more).As diamond tool, when work, is subjected to biggish cutting force, this requires Buddha's warrior attendant
There is firm binding force between stone particle and metallic matrix, prevents diamond drop-off；Diamond-metal high-heat-conductive composite material is main
It is prepared using powder metallurgy sintered or melt Infiltration Technics, preparation temperature is up to 500~800 DEG C.As heat dissipation used for electronic packaging
Component, it is desirable that have extremely low interface resistance between diamond particles and metallic matrix, so as to efficient heat transfer.To realize above-mentioned answer
With being required in the preparation of diamond-metal system and its application stage, the interface of diamond particles and metallic matrix is kept can
The metal metallurgy smelting leaned on combines.However, without chemical affinity, interface between the diamond crystal and above-mentioned metal that are constituted due to covalent bond
Nonwetting, diamond particles are generally mechanical interlock with metallic matrix, and interface binding power is very poor.Currently, solving the problems, such as this
Main method is: 1. having metallic element (W, Ti, Cr, Mo, V of strong carbide Forming ability in diamond particle surfaces plating
Deng), make diamond surface metallization by forming coating metal carbide；2. plating diamond particles are burnt with metal again
Knot or infiltration processing, are reacted by the counterdiffusion between carbide and metallic matrix, final to realize diamond particles and metallic matrix
Reliable metallurgical bonding.In addition, diamond surface thickness of coating must strict control.Coating is too thin, can not be effectively improved diamond
With the interface binding power of metallic matrix；Coating is too thick, and coating is easy to fall off under thermal stress effect, while can introduce biggish boundary
Face thermal resistance influences diamond-metal high-heat-conductive composite material heat dissipation effect.Currently, generally requiring Buddha's warrior attendant in diamond tool
Stone carbide surface layer with a thickness of 0.5~2 μm, Electronic Packaging thermal component generally require diamond surface carbide lamella with a thickness of
0.2~1 μm.
Currently, common diamond surface coating method mainly has vacuum PVD to plate (magnetron sputtering, vacuum
Ion plating etc.), chemical vapor deposition plating, powder covering sintering plating and the micro- evaporation of vacuum plate etc..Magnetron sputtering method can be in Buddha's warrior attendant
The various metal layers of stone coating surface, but typically just physical attachment between coating and diamond, interface binding power are poor.Using change
When learning vapor deposition metal lining, coating is chemically reacted with diamond at high temperature, and binding force of cladding material is high, but to plating
For granular diamond, since reaction gas phase is difficult to the particle uniformly in contact with diamond accumulation body everywhere, coating it is uniform
Property is poor, especially plating leakage phenomenon easily occurs at the diamond particles place of contacting with each other；In addition, the device is complicated for the technique, single plating
The amount of covering is low, and preparation cost is higher.The micro- evaporation plating of vacuum is the method for the wider diamond particle surfaces titanizing of current application, usually
It selects titanium trichloride and reducing agent titantium hydride is raw material.In temperature-rise period, titanium chloride volatilization, and the H being precipitated with titantium hydride2Occur
Reaction, restores gaseous metal Ti atom, deposits to diamond surface and forms coating.The more uniform cause of coating of the micro- evaporation plating of vacuum
It is close, but equipment cost is higher, plating technic is complicated.In addition, in the technique diamond particles be it is static, diamond particles are mutual
A possibility that there are still plating leakages for contact position.
Salt bath plating is that metal powder is added in chloride salt, utilizes the diffusion reaction of metallic atom in fused salt at high temperature
And a kind of surface treatment method of the coat of metal is obtained on plating piece surface.The advantage for carrying out salt bath plating to diamond particles exists
Enhanced primary treatment in: coating and diamond particles, binding force of cladding material is high, while the equipment and technology of salt bath plating it is simple, at
This is low, it is easy to accomplish industrialization production.There is researcher using magnesium chloride, sodium chloride and barium chloride as fused salt, 600~800
DEG C realize ti coat on diamond (Lv Jianwei, Zhao Qiang, An Huifen, the research of Ti-plated diamond surface by molten salt process, the electricity of diamond particles
Plating and covering with paint, 2006,25 (7): 17~20), but there are plating leakages for diamond edges and corners, while coating uniformity is poor.In addition, chlorination
Barium is noxious material, there is environmental protection and safety problem.There is researcher, as metal salt, to be heated to using sodium chloride and potassium chloride
900~1000 DEG C of heat preservation 2h diamond surface realize plating tungsten (Tang little Wen, the salt bath of diamond plate tungsten, mechanical engineering material,
1998,20 (6): 31~32), but follow-up study person has found, the diamond coating of this method preparation has apparent plating leakage phenomenon, difficult
To form even compact coating (see China Patent No. CN201310322141.0 " a kind of method of diamond surface plating tungsten ").In
State's patent No. 201610135627.7 discloses " a kind of method of diamond Electroplating from Molten Salts tungsten ", equally using salt bath process in diamond
Tungsten is plated on surface, and plating temperature is 900~1200 DEG C.But some researches show that when temperature is higher than 900 DEG C, diamond graphitization inclines
To obvious, diamond thermal damage big (Yin Fang, Huang Hui, Xu Xipeng, the experimental study of fine-granularity diamond soldering thermal damage, Buddha's warrior attendant
Stone and grinding materials and grinding tool engineering, 2013,33 (3): 21~25).
Since the carbide Forming ability of Ti element is better than the elements such as W, Cr, and the crystal structure of diamond and TiC have one
Determine corresponding relationship, Yi Shixian coherence strong―binding interface, while the temperature of Ti formation carbide is low, it is small to the thermal damage of diamond,
Therefore be directed to the titanizing of diamond particles, research and develop a kind of low cost and environmental protection, coating uniformly and it is fine and close, interface binding power is excellent
Plating technic, will be with important application value.
