Abstract
The utility model discloses a kind of Cu Sn Ti diamond brazing coating, including titanium layer, tin coating and the copper coating for being attached to diamond, tin coating is between copper coating and titanium layer.The utility model is high with diamond interface bond strength, can solve the problems, such as diamond drop-off well.
Description
Technical field
The technical field of cored solder is the utility model is related to, refers in particular to the diamond brazing coating of Cu-Sn-Ti a kind of.
Background technology
The high rigidity and desirable physical mechanical performance of diamond cause diamond tool turns into process various stiff materials not
The effective tool that can lack.Carcass Metal Substrate is to influence diamond tool to make on the caking property (the plating ability of carcass) of diamond
With one of principal element of life-span and performance.
Due to having very high interface energy between diamond and common metal and alloy, it can not be one to cause diamond particles
As low-melting alloy infiltrated, caking property extreme difference.In traditional metal base firing diamond tool manufacturing technology, diamond
Caused mechanical clamping force is embedded in carcass Metal Substrate after grain only leans on carcass shrinkage, without formed firm chemical bonded refractory or
Metallurgical binding, carcass are combined loosely with diamond interface, are caused diamond particles easily to be separated at work with carcass Metal Substrate, are deposited
Largely come off problem in diamond, greatly reduce life-span and the performance level of diamond tool.In most of impregnated type instrument
The utilization rate of diamond is relatively low, and a large amount of expensive diamonds come off at work to be lost among scrap.
Increase metal coating in diamond surface, coming off for diamond can be effectively improved, at present using most common metal
Coating is in the micro- evaporation titanizing of diamond surface.Because titanium coating is too thin, it is impossible to keep out carcass graphite element in sintering process
Erosion to diamond, titanium coating and carcass metal bond strength be not high, and the phenomenon of diamond drop-off is still more serious.
At present, make diamond (or cubic boron nitride) instrument with method for brazing to have started to turn into hot spot technology, cored solder is
Refer to the alloy formed by metal sinterings such as copper and tin titaniums, it is powdery or sheet；Cored solder is put into carcass metal when use
On, then diamond is put into cored solder, then heat-agglomerating is carried out, diamond is just tied on carcass metal.For example, China is specially
A kind of active solder alloy is disclosed in sharp CN201610763289, the active solder alloy contains the group of following mass percent
Point：Copper 45.0%~70.0%, zinc 3.0%~47.0%, tin 0.5%~40.0%, titanium 0.1%~15.0%.
Cored solder is fine to diamond surface wetability, high with diamond interface bond strength, and cored solder is made coating,
Should be able to solve the problems, such as diamond drop-off well, but how cored solder be made coating, there is presently no do well
Method.Therefore, the present inventor makes further research to this, develops a kind of Cu-Sn-Ti diamond brazing coating and its preparation side
Thus method, this case produce.
Utility model content
Technical problem to be solved in the utility model is the diamond brazing coating for providing a kind of Cu-Sn-Ti, with gold
Hard rock interface bond strength is high, and the diamond and other bonding materials sintering for coating cored solder coating have more preferable adhesion, energy
Solves the problems, such as diamond drop-off well.
In order to solve the above technical problems, technical solution of the present utility model is：
The diamond brazing coating of Cu-Sn-Ti a kind of, including titanium layer, tin coating and the copper coating for being attached to diamond, tin
Coating is between copper coating and titanium layer.
Further, diamond is 45-50 mesh.
The utility model first plates copper coating in diamond surface, then plates tin coating again, then the diamond plated
With titanium valve mixed sintering, Cu-Sn-Ti diamond brazing material coating has just been obtained.Bending strength test shows：Applied with cored solder
The calibrated bolck of layer diamond sintering is bigger than the standard bulk strength sintered with Ti-coated diamond.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Label declaration
The titanium layer 4 of 1 copper coating of diamond, 2 tin coating 3
Embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.Disclosed in the utility model is
A kind of diamond brazing coating of Cu-Sn-Ti, as shown in figure 1, be preferred embodiment of the present utility model, including titanium layer 4, tin
Coating 3 and copper coating 2, copper coating 2 are attached on diamond 1, and tin coating 3 is between copper coating 2 and titanium layer 4.
In the present embodiment, using the diamond 1 of 45-50 mesh.First on the surface of diamond 1, plated by electroless copper method
Copper coating 2, then, the diamond 1 for having plated copper is cleaned, is put into electrotinning or chemical plating stannum solution, plate tin coating 3, then
The diamond 1 plated and titanium valve mixed sintering, titanium layer 4 is formed, has just obtained Cu-Sn-Ti diamond brazing material coating.
The utility model directly does cored solder coating in diamond surface, does one layer of cored solder on the surface of diamond 1, makes
With when, have Cu-Sn-Ti cored solder coatings diamond 1 and bonding material mix, hot pressed sintering is blocking, makes on saw blade
Cutter head.After the utility model, shown by bending strength test：With the calibrated bolck of cored solder coating diamond sintering
Standard bulk strength than being sintered with Ti-coated diamond is big.
It is described above, only it is preferred embodiment of the present utility model, not technical scope of the present utility model is made
Any restrictions, therefore the change or modification done in every case according to claim of the present utility model and specification, should all belong to this practicality
Within the scope of new patent is covered.
Claims (2)
- A kind of 1. diamond brazing coating of Cu-Sn-Ti, it is characterised in that：Including titanium layer, tin coating and it is attached to diamond Copper coating, tin coating is between copper coating and titanium layer.
