Description
Technical field
The present invention relates to copper materials to be heat-treated modified field more particularly to a kind of high abrasion aluminium bronze and its manufacturing method.
Background technology
Aluminium bronze is the acid bronze alloy using aluminium as main alloy element, is the aluminium bronze containing iron, manganese element, belongs to high-strength
Heat-resisting bronze is spent, aluminum content is usually no more than 11.5%, is additionally added the elements such as suitable iron, nickel, manganese sometimes, further to improve
Performance.Aluminium bronze is heat-treatable strengthened, and intensity is higher than tin bronze, and high temperature oxidation resistance is also preferable.
In the prior art, general to be directly processed using the aluminium bronze raw material of supply of material state, this mode is simply straight
Connect, mouldability, suitable for most of occasions, but due to the supply of material state aluminium bronze state differ and structural homogenity relatively
Difference just shows less to adapt under the fretting wear operating mode for determining performance by micro-property.
Therefore, be badly in need of on the market a kind of even tissue, hardness are high, wearability is good, the high abrasion aluminium bronze of tissue nodularization and
Its manufacturing method.
Invention content
In view of the above defects of the prior art, the present invention is intended to provide a kind of even tissue, hardness height, wearability
Good, tissue nodularization high abrasion aluminium bronze and its manufacturing method.
To achieve these goals, the present invention uses following technical scheme：A kind of manufacturing method of high abrasion aluminium bronze, packet
Include following steps：
1）Prepare before production
1. raw material prepares：Prepare albronze QAl 10-4-4-4-4 supply of material state poles；
2. equipment and tooling prepare：Prepare high temperature protection atmosphere heating furnace, built-in heating equipment and mixing plant pure water tank, in
Warm protective atmosphere heating furnace, household freezer；
3. auxiliary process material prepares：Prepare enough argon gas；
2）It is modified
1. by the stage 1）1. albronze QAl 10-4-4-4-4 supply of material state poles that step prepares are put into the stage 1）2. height that step prepares
In temperature protection atmosphere heating furnace, enough argon gas are passed through, are then heated to 980 DEG C-985 DEG C, with albronze QAl 10-4-4-4-4 supply of material states
Diameter d (mm) the meter heat preservation 2.2min/d-2.5min/d of pole, obtain solid solution bar, then come out of the stove；
2. when 1. step carries out simultaneously open stage 1）The 2. heating equipment in pure water tank that step prepares to 60 DEG C of water temperature-
80℃；
3. opening the mixing plant in pure water tank, stirred with the rate of 40rpm-50rpm, the solid solution for then 1. obtaining step
Bar is transferred in 5s in pure water tank after coming out of the stove；
4. by the stage 1）2. household freezer that step prepares is cooled to（-50℃）-（-70℃）；
5. when step 3. in solid solution bar be cooled to identical with water temperature when transfer them in household freezer, keep the temperature 1h-2h, then
It takes out, solid solution bar returns back to room temperature naturally, and timeliness bar is treated in acquisition；
6. treat that timeliness bar is put into the stage 1 by what 5. step obtained）In 2. medium temperature protection atmosphere heating furnace that step prepares, it is passed through foot
Argon gas is measured, after then heating to 540 DEG C -550 DEG C, 4min/d-5min/d is kept the temperature, is then delayed with being no more than the speed of 5 DEG C/min
Slow cool down is to coming out of the stove after 300 DEG C, then natural air cooling to room temperature, that is, obtain needed for high abrasion aluminium bronze.
The high abrasion aluminium bronze manufactured using the above method, using QAl10-4-4 as raw material, through solid solution-hot water cooling-cold place
It is finally obtained after reason-timeliness heat preservation-nodularization slow cooling processing, interior hardening constituent is in nodularization state.
With existing Technical comparing, the present invention has the following advantages as a result of said program：（1）Different from the prior art
Aluminium bronze directly using supply of material state carry out part processing, the present invention aluminium bronze bar has been carried out again it is fully and completely hot
Processing is modified, wherein using a little higher than routine techniques during solid solution（960℃）Temperature be dissolved, this is because we have found that make
For complicated pluralism element alloy, QAl10-4-4 can no doubt grow up as crystal grain occurs for the promotion of solid solubility temperature, mechanical performance declines etc.
Negative effect, but when applied to fretting wear operating mode, it is this to negatively affect the wear-resisting property for hardly influencing aluminium bronze,
Instead due to temperature higher, solid solution is more abundant, and obtaining uniform metallographic structure for the later stage lays the foundation.（2）Using warm water
Cooling and cold treatment are the innovative points of the present invention, more easy to crack if cold water cooling is directly used according to practice（Especially
In the case where the present invention improves solid solubility temperature）, and the medium cooling for using other cooling rates relatively low then can be due to copper rod surface
Cooling and internal difference cooling time lead to nonuniform organization greatly, and according to fatigue principle, non-uniform tissue is opposite to fit
Answer uniform and lasting fretting wear operating mode.And warm water is used to cool down, due to reducing temperature difference, tearing tendency is greatly reduced,
It will not lead to nonuniform organization since cooling rate is excessively slow simultaneously, and solid solution structure can be made to retain more completely, more using cold treatment
Uniformly, it lays a solid foundation for post-processing.（3）The core innovative point of the present invention is ag(e)ing process, and the present invention passes through a little higher than normal
The aging temp for advising temperature obtains more hardening constituents, then allows the gradual nodularization of the hardening constituent of precipitation by the process of extremely slow slow cooling
Disperse（Principle is roughly approximated to the spheroidising of high-carbon steel, but does not have research to embody in prior art theory, is sent out by putting into practice
It is existing）, final to obtain, the hardening constituent of nodularization and disperse is evenly distributed on relatively soft matrix, can be obviously improved material
Wearability, under the simple fretting wear operating mode of identical operating mode in use, the aluminium bronze through the present invention compare QAl10-4-4 without
The conventional QAl10-4-4 aluminium bronzes service life of processing grows 5 times -7 times, and the course of work is more steady, noise smaller.
