Abstract
The present invention provides a kind of method of measurement vitrified bond to diamond hold.Belong to grinding materials and grinding tool and technical field of superhard material.Its technical scheme is：By the way that vitrified bond and diamond abrasive grain are made into vitrified bond piece Diamond Ceramics bonding agent piece three-decker, and more than bonding agent refractoriness 30 DEG C or so be sintered, obtain the sintered body with certain bonding strength, then this sintered body both ends is stained with tension block respectively with super glue, and its tensile strength is measured on instron, obtain the interface binding power F of vitrified bond and diamond, then make vitrified bond batten and measure its rupture strength σ, embody the size of hold jointly with interfacial force F and rupture strength σ.The advantages of the method is：The interface binding power of vitrified bond and diamond can be effectively measured, foundation is provided for the research and development manufacture of diamond tool.
Description
Technical field
Patent of the present invention belongs to grinding materials and grinding tool and technical field of superhard material, and in particular to one kind measurement vitrified bond pair
The method of diamond hold.
Background technology
Hold refers to that in diamond tool carcass makes Buddha's warrior attendant to the mechanical snap power and surface reaction forces of diamond
The firm bonding of stone and the power not fallen off.Under normal circumstances, carcass is bigger to the hold of diamond, and diamond is just less susceptible to
Split away off from carcass, so as to give full play to the shear action of diamond.Mostly it is with gold in diamond tool research and development at present
The practical effect of diamond tool is as foundation, to estimate bonding streng of the carcass to diamond, this mode not only cost
Height, complex procedures, and due to during instrument use other factors equally influence the using effect of diamond tool, therefore
The holding force data gone out is unreliable.
Therefore, the present invention is directed to diamond tool hold in industrial production and is difficult to be asked with what existing method was accurately weighed
Topic, propose a kind of method of measurement vitrified bond to diamond hold.
The content of the invention
Technical problem：The technical problem to be solved in the invention is the hold of diamond tool in industrial production with existing
Method be difficult to accurately weigh.
Technical scheme：To achieve these goals, the present invention provides a kind of measurement vitrified bond to diamond hold
Method comprise the following steps：
1. select a kind of vitrified bond powder and be molded two panels vitrified bond piece with it；
2. uniformly smearing a layer binder on 1. vitrified bond piece that step is molded, and last layer diamond is uniformly glued, so
Another vitrified bond piece is attached to above diamond layer afterwards, forms vitrified bond piece-diamond-vitrified bond piece knot
The composite sheet of structure；
3. the vitrified bond piece-diamond-vitrified bond piece composite sheet of step 2. middle making is sintered, sintered
Composite sheet；
4. by step 3. in obtain sintered combined be bonded in tension block with strength adhesive and to do stretching experiment and obtain pulling force
F；
5. the bonding agent 1. selected using step makes vitrified bond batten, and surveys its rupture strength σ；
6. 5. σ that 4. F that step obtains and step obtain reacts the size of hold jointly.
The forming method of the step 1. middle vitrified bond piece is：In dry-pressing formed, moulding by casting and gel forming
It is a kind of.
2. diamond grit answers >=100 mesh to the step in diamond layer, and size distribution is only poor answers≤5 mesh, arrangement
Answer uniformity, or ordered arrangement.
3. middle vitrified bond piece-diamond-vitrified bond piece composite sheet sintering temperature should be than step 1. for the step
The refractoriness of selected vitrified bond is high 20 DEG C ~ and 50 DEG C.
The step 4. described in strength adhesive adhesion strength should be greater than 20MPa.
The beneficial effect comprise that：The present invention can effectively measure the interface cohesion of vitrified bond and diamond
Power, foundation is provided for the research and development manufacture of diamond tool.
