Description
Technical field
It is the present invention relates to Study on Brazed Superabrasive Tools manufacturing technology field, in particular to a kind of to be combined with active alusil alloy
The method of agent soldering super hard abrasive.
Background technique
Super hard abrasive typically refers to diamond abrasive and two kinds of cubic boron nitride abrasive materials.Because super hard abrasive intensity is high, hardness
Greatly, it is often manufactured into miscellaneous super hard abrasive tool and carrys out the hard brittle materials such as processing stone material, ceramics, hard alloy.Currently,
Prepared by the super hard abrasive tool of bonding agent of metal, the connection of super hard abrasive and tool base mainly passes through plating, be sintered with
And the means such as soldering are realized.For super hard abrasive tool is electroplated, the consolidation style of super hard abrasive is mechanical package, and abrasive material combines
Power is weak, is easy to fall off failure, and super hard abrasive is in unordered, proud exposure is low, chip space is small；For being sintered super hard abrasive work
Tool, super hard abrasive proud exposure is small, while super hard abrasive and alloy can not achieve complete enhanced primary treatment, abrasive material binding force
Small, sword is also difficult to solve from sharp problem out.Based on these there are the problem of, method for brazing prepares super hard abrasive tool and comes into being.
In the super hard abrasive tool of method for brazing preparation, there is chemical bonding in super hard abrasive and metallic bond interface, have higher company
Connect intensity, better peel performance；Compared to traditional multi-layer sintering technique, method for brazing can be mentioned the exposure degree of super hard abrasive
It is high by 70%~80%, greatly improve the appearance bits ability and stock-removing efficiency of super hard abrasive tool.Super hard abrasive is prepared based on method for brazing
The superiority of tool, being brazed super hard abrasive in this field is always the research hotspot of scholars.
The metallic bond that mainstream is used to be brazed super hard abrasive at present mainly has a three classes, Ni-Cr base (brazing temperature: 950~
1160 DEG C), Ag-Cu base (brazing temperature: 740~970 DEG C), Cu-Sn base (brazing temperature: 880~1150 DEG C).For Ni-Cr
Base Metal bonding agent, brazing temperature is high, and the mechanical performance of diamond and cubic boron nitride abrasive materials is lost seriously；Particularly, for
For diamond abrasive, since the presence of Ni element makes diamond abrasive graphitization serious.Ag-Cu Base Metal is combined
Agent causes Ag-Cu Base Metal bonding agent expensive since Ag belongs to precious metal.Based on these problems, although Cu-Sn base
The mechanical strength of metallic bond does not have the good of Ni-Cr base, but since it is relatively small to the damage of super hard abrasive, cost also compared with
Ag-Cu metallic bond it is inexpensively very much, the application of Cu-Sn Base Metal bonding agent becomes more and more in recent years.Except this it
Outside, the solder hierarchy of mainstream welding super hard abrasive, brazing temperature are generally higher；High brazing temperature can not only damage diamond
The mechanical performance of itself, while will lead to very high residual stress, these are prepared desired by Study on Brazed Superabrasive Tools
's.Metallic bond suitable for soldering super hard abrasive in the market, in particular for the metal knot of low temperature brazing super hard abrasive
Mixture, there is no too many selections.The high reason significant portion degree of brazing temperature is mutually melted by solder alloy matrix
Caused by (Ni-1453 DEG C, Cu-1083 DEG C and Ag-962 DEG C) of point high.Therefore, novel suitable soldering super hard abrasive is developed to use
Metallic bond solder, especially be suitble to low temperature brazing super hard abrasive metallic bond solder, to soldering super hard abrasive
The further development of tool is even more important.
In view of the problem present on, invention provides a kind of active alusil alloy bonding agent soldering superhard abrasive
On the one hand the method for material can be realized the secured welding of super hard abrasive, brazing cost be effectively reduced, extend existing soldering superhard abrasive
The solder hierarchy of material；On the other hand, this method can be realized super hard abrasive and be welded under relatively lower temp, reduce super
The thermal damage of hard grind material brazing process.
