Description
Technical field
The present invention relates to field of metal alloy technology, particularly relate to a kind of tin bronze alloys powder and preparation method thereof.
Background technology
Tin bronze alloys, as powder metallurgy, friction material and oil containing bearing material, Diamond Tool Matrix by extensively
General application.In recent years, the industry high speed development such as powder metallurgy, diamond tool, ornament materials, the application of tin bronze alloys powder is also
More and more extensive.The most commonly used atomized alloy technique, hybrid technique, oxidative deamination process three productions method are entered at present
Row large-scale production, the performance of the powder produced according to different production technologies is also not quite similar.Wherein, water atomization produces
Tin bronze powder is cheap, but fast due to water-cooled speed in production process, and its hardness is relatively big, and the stannum that water atomization simultaneously produces is blue or green
Copper powder has bigger apparent density, and processability is poor.The tin bronze powder that mixing method produces, has good mouldability, but
Its easily segregation during transport, molding etc., intensity is relatively low, and shrinkage factor is wayward.
Summary of the invention
For the deficiencies in the prior art, an object of the present invention is to provide a kind of tin bronze alloys powder, and pine fills close
Spend low, good moldability.
For reaching this purpose, the present invention by the following technical solutions:
A kind of tin bronze alloys powder, by weight percentage, prepare raw material include 5%～40% cupric oxide powder,
The zinc powder of signal bronze powder, 0～20% of 60%～90%, the weight of such as cupric oxide powder accounts for the 5% of raw material total amount, 10%,
15%, 20%, 25%, 30%, 35%, 40%, the weight of signal bronze powder accounts for the 60% of raw material total amount, 65%, 70%,
75%, 80%, 85%, 90%, the weight of zinc powder accounts for the 1% of raw material total amount, 2%, 3%, 4%, 5%, 10%, 15%, 20%.
By copper powder is pre-oxidized, broken, substantially increase the utilization rate of copper powder, reduce production cost, simultaneously by
After copper aoxidizes, what in reducing atmosphere, diffusion-sintering process was carried out is that activity diffusion-sintering, relatively copper powder are directly closed with copper and tin
Bronze diffusion-sintering is easier to, and alloying process is more prone to carry out；Wherein, it is prepared as with electrolytic copper powder due to water atomization copper powder
This is the most relatively low, draws materials easily, is wherein not excluded for adopting the copper powder prepared in other ways, thus use cupric oxide powder be water atomization process or
Copper powder prepared by electrolysis is fired, the broken cupric oxide powder prepared, due in oxidizing process, and the restriction of oxidizing condition, therefore
In described cupric oxide powder, oxygen content is 16%～20%, such as 16%, 17%, 18%, 19%, 20%.
Wherein, the mesh number of described cupric oxide powder is-200 mesh, selects the cupric oxide powder of this mesh number, it is simple to formed relatively after sintering
Low apparent density.
Wherein, the cost that signal bronze powder is prepared in employing water atomization is relatively low compared with other costs, water atomization signal bronze simultaneously
Powder has excellent mobility, therefore signal bronze powder uses the atomization signal bronze powder that water atomization process prepares, described copper
Arranging in pairs or groups for convenience in ashbury metal powder, wherein the content (mass percent) of copper is 50%～90%, such as copper content is 50%,
60%, 70%, 80%, 90%, Theil indices is 10%～50%, and such as Theil indices is 10%, 20%, 30%, 40%, 50%.
Wherein, described zinc powder is the zinc powder that aerosolization method prepares.
The copper powder that the present invention selects atomization or electrolytic copper powder to prepare prepared cupric oxide powder fired, broken, atomization copper and tin
Alloyed powder, aerosolization zinc powder are raw material, by pre-oxidizing atomized copper powder or electrolytic copper powder, broken, substantially increase mist
Change the utilization rate of copper powder, reduce production cost, simultaneously because after copper oxidation, diffusion-sintering process is carried out in reducing atmosphere
Being that activity diffusion-sintering, relatively copper powder are directly easier to signal bronze powder diffusion-sintering, alloying process is more prone to carry out.Can
Suitably reduce the temperature of copper and tin diffusion, reduce energy consumption.For the tin bronze mode of production that this method is more traditional, at follow-up tune simultaneously
The composition of whole customer demand, quality control has only in mixed process, is greatly improved the utilization rate of product, and stock buildup is had enough to meet the need
Rate, reduces the operation cost of enterprise.On the other hand, the tin bronze powder that this method produces, owing to being that powder loose sintering is laggard
Row is broken, and the most each granule is granule composition, has relatively low apparent density, good mouldability, is making oil-containing axle
The porous part such as hold and there is the biggest advantage.
The two of the purpose of the present invention are to provide the preparation method of a kind of tin bronze alloys powder, and technique is simple, preparation
Tin bronze alloys powder, apparent density is low, good moldability, comprises the following steps:
1) use water atomization process or Preparing Copper Powder by Electrolysis, copper powder is carried out roasting, crushes, obtain cupric oxide powder；
2) water atomization process preparation atomization signal bronze powder is used；
3) aerosolization method is used to prepare zinc powder；

It is placed in mix homogeneously in Double cone mixer, prepares tin bronze powder precursor；
5) by step 4) the tin bronze powder precursor for preparing is placed in reducing atmosphere and carries out heat treatment, it is achieved oxidation
Copper powder in reduction process with the co-diffused of signal bronze powder Yu zinc powder, prepare tin bronze composite powder；
6) by step 5) tin bronze composite powder after heat treatment carries out crushing and screening through disintegrating machine, and prepare tin bronze and close
Bronze end.
Step 4) in, the time of described mixing is 45min.
Step 5) in, the temperature of described heat treatment is 400～800 DEG C, and the time of described heat treatment is 1.5～4h.
Compared with prior art, the invention have the benefit that the tin bronze alloys powder of the present invention, by weight percentage
Meter, prepares the zinc powder of signal bronze powder, 0～20% that raw material includes cupric oxide powder, 60%～90% of 5%～40%；This
Bright selection cupric oxide powder, signal bronze powder, zinc powder are raw material, and by regulating the proportioning of each raw material, the tin bronze alloys of preparation
Apparent density of powder is low, good moldability；By copper powder is pre-oxidized, broken, substantially increase the utilization rate of copper powder, reduce
Production cost, simultaneously because after copper oxidation, what in reducing atmosphere, diffusion-sintering process was carried out is activity diffusion-sintering, relatively copper
Powder is directly easier to signal bronze powder diffusion-sintering, and alloying process is more prone to carry out；By cupric oxide powder, signal bronze
Powder, zinc powder mix homogeneously are placed in steel belt reduction furnace, carry out high-temperature heat treatment, then breaking through disintegrating machine under reducing atmosphere
Broken screening obtains tin bronze alloys powder.The preparation method technique of the present invention is simple, and the tin bronze alloys powder of preparation, pine fills close
