Description
Technical field
The present invention relates to a kind of metallurgical powder, is particularly used for the complete pre-alloyed Buddha's warrior attendant lapicide for manufacturing diamond tool
Have carcass powder, belong to powdered metallurgical material technical field.
Background technology
As industry competition aggravates, the industry such as stone material, ceramics, engineering construction is to reducing cost, carrying efficient requirement day
Beneficial strong, domestic and international market rises rapidly to the demand of high-performance diamond instrument.Generally manufacturing the method for diamond tool is
First diamond is mixed with metal dust, then by this mixture cold-press moulding, repressurization or be not pressurized sinters into closely solid
Caking.Wherein, metal dust holds diamond as cutter carcass binding agent, and the factor such as its material composition and granularity can be to Buddha's warrior attendant
Stone cutting performance produces material impact.
Artificial diamond tool is widely used in the drilling of geological drilling and hard brittle material, cutting, grinding, polishing etc.
Processing.Need that the diamond tool product with definite shape and mechanical performance is made using carcass material auxiliary.Carcass material
Effect be to support and hold diamond, maintain sharp ability, prevent diamond from coming off too early.Traditional carcass material is by list
Elemental metal powders or single alloy powder carry out mechanical mixture acquisition, and the carcass sintering temperature that this method obtains is higher, stably
The abundant alloying poor, that each composition can not be reached of property and matrix composition is also difficult to uniformly, it is poor to the hold of diamond etc.
Many unfavorable factors.
Usually require that metal dust there should be good sintering reaction activity.Good sintering reaction activity means metal
Powder can sinter at relatively low temperature to be reached solid density and only needs very short sintering close to solid density, or sintering
Time.High sintering temperature can cause following major defect:Sintering mold service life reduction, damnification of diamond grits and higher energy consumption.
It should be no more than 850 DEG C to give full play to the superior function of diamond its carcass maximum sintering temperature.Carcass sintering is completed can use
To relative density characterize:In general, relative sintered density reaches 98% or more and can be considered as close to solid density.Shadow
The primary factor for ringing sintering tyre-e/or performance is the composition of powder.Selection powdered ingredients will be not only considered to sintered body performance, especially
It is the requirement of the hold to diamond, toughness and wearability, and takes into account cost factor.Influence the second of tyre-e/or performance
Individual key factor is the grain size proportion of powder, and in the case of other conditions identical, the sintering activity of thinner powder is substantially excellent
In thicker powder.Another factor is exactly the oxidation on powder surface, and because powder size is thin, surface-active is high, is exposed to
It in air, will be easy to aoxidize, so as to form oxide skin(coating) in powder particle surface, and then prevent entering for sintering reaction
OK, thus reduce powder sintering reaction activity.
Carcass material uses metal simple-substance powder and part pre-alloyed powder more in the prior art, so being wrapped in carcass powder
Contain the various elements of composition carcass, reduced fusing point and easy-sintering, there can be the efficiency for playing diamond.
The content of the invention
It is an object of the invention to each composition proportion and diamond wear resistance ratio are uncoordinated in prior carcass material in order to solve,
And matrix composition is uneven, less stable, sintering temperature is higher, it is weaker to diamond hold the defects of and provide a kind of complete
Pre-alloyed diamond tool tyre case powder.
