Description
Technical field
The present invention relates to a kind of method of utilization powder metallurgy carbon nano-tube in situ/aluminium composite material, belongs to powder
Last metallurgical technology field.
Background technology
Aluminum and its alloy are content highest metal substances matter in the earth's crust, are to be only second to the second largest of iron and steel in commercial Application
Metalloid material.The density of aluminum is low, only 2.7g/cm3, electrical and thermal conductivity performance is good, damping characteristics are good, be widely applied to
Automotive hub, Aero-Space framework, mechano-electronic and some civil areas.But, the intensity of fine aluminium is relatively low, high-strength at some
The field that degree is required fails to produce a desired effect.Meanwhile, in the course of processing in later stage, aluminium also needs to keep certain deformation energy
Power.Therefore, how to improve the intensity of aluminium and keep certain plasticity and toughness to become the focus of current research.In recent decades, it is many
Number research worker is all to add different types of alloying element to prepare various section bars through the technique of melting and casting in aluminum substrate.
However, the regulation and control of these alloying elements content in adding procedure are simultaneously inaccurate, Partial Elements are difficult to add and cost intensive.This
Outward, the addition of alloying element there are problems that a lot in terms of causing the performance evaluation of material later stage.In recent ten years, people attempt again
Add some enhancings mutually to improve the performance of composite in metallic matrix.But, these traditional methods are always original to sacrifice
Based on material some performances, and the aluminum matrix composite being prepared into by the method for vapour deposition in situ can be maximum
Overcome this shortcoming.According to composite Materials Design rule (δc=(1-f) δm+fδp), strengthen phase is added in realization reinforcing effect
While, the weak point of matrix material can also be avoided, so as to obtain the aluminium of high-strength light.
CNT from last century since the nineties are found, by insider extensive concern and expansion grind in a large number
Study carefully, begun to take shape now.In recent ten years, the carbon nano tube enhanced aluminium base composite wood for being prepared with CNT as reinforcement
The research of material increases year by year and develops rapidly.So far, great majority research concentrates on additional method and prepares CNT enhancing aluminum
On based composites, block composite wood is prepared by techniques such as powder metallurgy, mechanical ball milling, molecular level mixing, casting smeltings
Material.But, above method can cause the destruction of carbon nano tube structure unavoidably, while being also difficult to ensure that CNT in matrix material
In it is dispersed.So, this is also that the bottleneck of current research is located.To sum up, how to solve CNT in the base equal
Even dispersion is with the interface cohesion that promotes CNT and matrix good and completely becoming for holding self structure currently prepare carbon and receive
The focus of mitron reinforced aluminum matrix composites is located.
So far, most research worker are prepared for CNT increasing using addition method of the CNT in aluminum substrate
Strong aluminum matrix composite.Method of the present invention using the additional powder metallurgy of vertical heater in-situ growing carbon nano tube, first in aluminium powder table
Uniform growth CNT on face, after through cold moudling and the technique of hot extrusion, prepare that consistency is high, CNT is equal
Even dispersion and the aluminum matrix composite of good mechanical performance.
The content of the invention
It is an object of the invention to provide a kind of side of easy powder metallurgy carbon nano-tube in situ/aluminium composite material
Method.The method can effectively overcome traditional additional carbon nanotube enhanced aluminium-based composite material to strengthen the uneven shortcoming of distributed mutually,
This procedure is relatively easy, and obtained composite materials property is preferable.For achieving the above object, the present invention by with
Lower technical scheme is carried out：
It is a kind of that the method that gaseous carbon source prepares CNT/aluminium composite material is catalyzed in aluminium powder surface in situ including following
Step：
(1) prepare precursor powder
With Nickelous nitrate hexahydrate as catalyst, dehydrated alcohol as dispersant, pure aluminium powder as raw metal, according to catalyst：

Make homodisperse mixed solution；Subsequently by solution, in water-bath, heated and stirred to ethanol is evaporated and obtains precursor powder powder
End；
(2) carbon nano-tube in situ/aluminium composite material
Precursor powder obtained in step (1) is placed in into vertical heater situ synthesizing carbon nanotubes/aluminium composite material：It is passed through
Carbon-source gas are methane, and reducing gas is hydrogen, and shielding gas is argon；Sintering temperature is 500～630 DEG C, and the recovery time is 0.5
～1.5h；Gaseous carbon sources grow carbon pipe under catalyst action, obtain the carbon nano tube enhanced aluminium base composite powder of growth in situ
End；
(3) prepare CNT/aluminium block composite material
By the composite powder obtained in step (2) after mechanical ball milling technique it is cold-rolled sintered after hot extrusion molding prepare block
Body material.
Preferably, step 1) water bath heating temperature be 90 DEG C, mixing time be 3 hours.Step 2) gas flow control model
Enclose for 100～300ml/min of argon；50～200ml/min of hydrogen；20～50ml/min of methane；Step 3) in mechanical milling process,
