Abstract
The invention provides a method for manufacturing a diamond saw blade. The method for manufacturing a diamond saw blade comprises the steps that nanometer element powder, superfine prealloy powder and diamond powder are used as raw materials, a diamond tool bit is obtained through material mixing and hot pressed sintering, the diamond tool bit is welded to a steel base body, and then the diamond saw blade is obtained. According to the method for manufacturing the diamond saw blade, combination of the nanometer powder and the superfine preallloy powder is optimized, the characteristics of the nanometer powder and the superfine prealloy powder are synthesized, the sintering temperature is significantly lowered, the sintering density is increased, the alloying extent of elements and the evenness of the elements are improved, the grain size accuracy is improved, the heat damage to diamond is reduced, the holding force of a matrix to the diamond is improved, in this way, the mechanical property of the saw blade and the cutting performance of the saw blade are improved, and the service life of the saw blade is prolonged.
Description
Invention field
The present invention relates to a kind of preparation method of diamond saw blade, belong to superhard material and manufacture field.
Background of invention
Along with the development of Ornamental Stone Industry, require high-performance and diamond saw blade cheaply.But because diamond belongs to nonmetal, there is no good affinity with metal, cause and between diamond and common metal or alloy, have very high interface energy, in order to improve diamond and carcass adhesion in diamond tool, people can take the method raising method of surface alloying, surface coarsening to improve diamond and carcass cast setting power conventionally; By vapour deposition process, chemical plating, then heat treating process, salt bath method make diamond and metal form chemical bonds.Although these methods can improve the adhesion of diamond and carcass in diamond tool to some extent, can't thoroughly solve the not firm problem of diamond and carcass adhesion in diamond tool.
In addition, the performance of diamond tool depends on the character of carcass to a great extent, therefore, and about the research of carcass powder is subject to paying close attention to widely in industry.Adopt pre-alloyed powder as diamond tool tyre case, have the following advantages: (1) can select according to the performance of target the carcass of heterogeneity, improve the specific aim of the use of instrument; (2) diamond tool that adopts pre-alloyed powder to manufacture, has improved compactness and the uniformity of carcass, thereby has improved the state of wear of carcass; (3) diamond tool that adopts pre-alloyed powder to manufacture, can improve the ability that carcass plates it, and shock resistance is better; (4) pre-alloyed powder is not oxidizable, and it is convenient to preserve, and can simplify the manufacturing process of instrument, obtains good economic benefit.Therefore, about the research of carcass powder is subject to paying close attention to widely in industry.Pre-alloyed powder is because its sintering temperature is low, and controlling property is good, and sharpness is high, cost is low and enjoy favor, applies also expanding day, becomes the development trend in diamond tool field.
But the kind of stone material is different with the place of production, its characteristic is also not quite similar, and this just requires diamond saw blade in the time of these different stone materials of cutting, shows equally excellent cutting efficiency and service life.This just need to suitably regulate matrix composition.Therefore, all matrix formulas of using all can not be made to prealloy powder.When actual use, need the approximate prealloy powder of selection component to add again element powder and regulate.
It is tiny that granularity is that the ultra-fine prealloy powder of several microns big or small has granularity, and sintering activity is high, can lower temperature under sintering densification; And crystal grain is tiny, carcass excellent combination property.But the element powder adding is at present a few to tens of microns normally, add in ultra-fine prealloy powder, can not give full play of the advantage of ultra-fine prealloy powder.
Summary of the invention
The invention provides a kind of preparation method of diamond saw blade, comprise that using nano-element powder and ultra-fine prealloy powder, bortz powder is raw material, obtain diamond segment through batch mixing, hot pressed sintering, diamond segment is welded on and in steel matrix, obtains diamond saw blade, the granularity that it is characterized in that nano-element powder is not more than 100 nanometers, ultra-fine prealloy powder is coreduction pre-alloying powder, and granularity is not more than 5 microns.
The present invention is by optimum organization nano powder and ultra-fine prealloy powder, the feature of nano powder and ultra-fine prealloy powder is combined, significantly reduce sintering temperature, improve sintered density, strengthen alloying level and the uniformity coefficient of element, refining grain size, reduces adamantine fire damage, improve carcass to adamantine hold, thereby improve saw blade mechanical property and saw blade cutting ability and service life.
Detailed description of the invention
Diamond saw blade production process comprises the processes such as steel matrix processing, batch mixing, hot pressed sintering, welding, wherein sintering is most important one critical process during diamond saw blade is produced, and the quality of sintering process directly affects cutter head density, hardness and the cutting ability of diamond saw blade.Thereby the sintering activity of raising metal dust, the sintering temperature of reduction carcass, reduces, to adamantine damage, can improve diamond saw piece performance.In addition, by each element of carcass powder need to be in sintering process abundant alloying, the function of each element of competence exertion.Element powders particle need to spread and realize alloying in sintering process, therefore in advance by element alloyed, uses prealloy powder can obviously shorten the diffusion-alloying time of element in the time of sintering, can reduce equally adamantine damage.Generally speaking, use ultra-fine prealloy powder can obviously improve the combination property of diamond saw blade.
But in order to regulate the composition of carcass, when carcass batching, add part element powders and regulate.The present invention uses nanoscale element powders, by making full use of the high activity of nanometer powder and minimum particle size, fully reduces sintering temperature, shortens alloying time, stock-removing efficiency and the service life of further improving diamond saw blade.
Diamond saw piece preparation method of the present invention, comprise that using nano-element powder and ultra-fine prealloy powder, bortz powder is raw material, obtain diamond segment through batch mixing, hot pressed sintering, diamond segment is welded on and in steel matrix, obtains diamond saw blade, the granularity that it is characterized in that nano-element powder is not more than 100 nanometers, ultra-fine prealloy powder is coreduction pre-alloying powder, and granularity is not more than 5 microns.
This project is by optimum organization nano powder and ultra-fine prealloy powder, the feature of nano powder and ultra-fine prealloy powder is combined, significantly reduce sintering temperature, improve sintered density, strengthen alloying level and the uniformity coefficient of element, refining grain size, reduces adamantine fire damage, improve carcass to adamantine hold, thereby improve saw blade mechanical property and saw blade cutting ability and service life.
