Description
Technical field
The present invention relates to damper knuckle supports and preparation method thereof, belong to metal material field.
Background technology
Damper is usually fitted in automobile suspension system, damper, which can effectively weaken road surface fluctuating etc., causes automobile
Damage.Knuckle in damper is one of important part, can make vehicle steadily traveling and sensitive transmission travel direction.Turn
It is the bridge of both unicom to section holder, is to transmit and bear automobile fractional load, support and drive preceding motor turning.In automobile
Under transport condition, it subjects changeable shock loading, therefore, often requires that it has very high intensity.
Damper knuckle support is usually prepared by steel alloy.But the general weight of steel is larger, but intensity is but
It is barely satisfactory, now all toward close on the materials such as aluminium alloy.Aluminium alloy refers to that a certain amount of magnesium, silicon, chromium is added based on aluminium
Equal addition element simultaneously control impurity content and the alloy system that forms.Aluminium alloy have high intensity, high rigidity, it is light-weight and
Good ductility, particularly suitable for making structural material.The processing technology of aluminium alloy is other than traditional casting technique, powder smelting
Gold is to select well.Powder metallurgy is to produce metal powder or (or metal powder and non-metal powder is mixed with metal powder
Close object) it is used as raw material, by shaping and being sintered, manufacture the technology of metal material, composite material and various types product.
And traditional damper knuckle support is to use steel alloy die cast, machining turning, purged and packed finished product,
The disadvantage is that since the tolerance grade of die casting is extremely difficult to technology requirement, must machine to ensure concentricity, the verticality of product
And portion size.
It is low for traditional kirsite shock absorber piston hardness, it is not wear-resisting the shortcomings of, Chinese patent
(ZL201210415179.8) a kind of obtained piston lever of reducer of use ferrous based powder metallurgical method is disclosed, product gas is improved
Density and product density.It is asked however, the patent solves damper knuckle support hardness, wearability and intensity etc. there is no display
The material and method of topic.
Invention content
In view of the above problems, the present invention provides high intensity, high rigidity, corrosion resistant damper knuckle support.
To achieve the goals above, the present invention uses following technical scheme：
Damper knuckle support, the holder are made of the following raw material：
Si powder：4-8 parts
Mn powder：2-4 parts
Alloy nano particle：1-5 parts
Ni powder：1-3 parts
Mg powder：3-5 parts
Al powder：2000-2500 parts.
The present invention is special to add alloy nano particle in the composition of traditional aluminium alloy, and alloy nano particle can be
Common or uncommon metal composition, mainly contributes on reinforcing mealy structure.
Preferably, the grain size of the Si powder, Mn powder, Ni powder, Mg powder, Al powder is 500-900nm.Control the grain of material
Diameter has a direct effect for the crystal grain refinement in aluminium alloy, and crystal grain refinement be make alloy have high intensity have concurrently high tenacity,
The key of low brittle transition temperature characteristic.
Preferably, the alloy nano particle is grown by metallic compound reduction.Directly by several metal meltings
It is mixed to form alloy, the smaller particle of grain size can not be formed in technique, and reduction method can obtain nano-scale particle, and control micro-
Grain size.
Further preferably, the metallic compound is PdCl2、H2PtCl6One or both of.The noble metals such as palladium, platinum are gathered around
There is extremely strong stability, the compound formed is easy to be reduced, and two kinds of metals that acquisition is restored under same environment can be handed over
Wrong, superposition, forms Nanoalloy particle.
The present invention additionally provides another technical solution while reasonable selection material mixture ratio：
The preparation method of damper knuckle support, includes the following steps：
(1) pre-treatment：It is weighed by above-mentioned raw materials, Si powder, Mn powder, Ni powder, Mg powder, Al powder is put into after evenly mixing
In container, sodium hypophosphite solution is added, dissolves PdCl with solvent 12It is formed and mixes liquid 1, solvent 2 dissolves H2PtCl6It is formed and mixes liquid 2, then
It is added dropwise into container and mixes liquid 1, the mixed formation of liquid 2 alloy nano particle, be uniformly mixed to obtain mixed-powder；
(2) it is molded：Mixed-powder is cleaned, drying, then mixed-powder is inserted in mold, obtains holder blank；
(3) it is sintered：Blank is pre-sintered, re-sinters and handles to obtain holder semi-finished product；
(4) it is surface-treated：In holder surface of semi-finished spraying alloy pulp, fire to obtain holder finished product.
In powder metallurgical technique, if each alloy component is directly milled into powder, molding is remixed, it inevitably can be because of component
The difference of grain size and cause sintering product cracking.The present invention is by chemical reduction method, by PdCl2、H2PtCl6It is respectively formed
Mixed liquid forms Pd-Pt nanometers of seeds under the reduction of sodium hypophosphite, since the seed particle size just generated is minimum (being in nanoscale),
The gap being easily accessible between large-sized powder (Si powder, Mn powder etc.) will continue to then with the increase of the mixed liquid of dropwise addition
It is grown on seed, until being full of gap, and then extends out, branch shape rock-steady structure form can be formed, it at this time could be first
Step is combined all powder in advance, avoids generating gap when molding, and then product when sintering is avoided to crack.
And alloy pulp when being surface-treated is also the constituent for fully taking into account alloy product, it can be with alloy product table
Face is strong bonded.
Preferably, step (1) solvent 1 is one or both of methanol, glycerine, solvent 2 is in water, ethyl alcohol
It is one or two kinds of.The lysigenous mixed liquid of solvent is conducive to disperse so that palladium, platinum element are easier to enter in gap.
Preferably, step (4) described alloy pulp is specially：Linalool：60-70%, ethyl oleate：1-5%, surplus
For LaCaMnO3Powder.It is prepared for LaCaMnO by solvent of linalool3Powdery pulp is changed by adding ethyl oleate and being ultrasonically treated
The dispersion performance of kind slurry, when ethyl oleate is less, to the dispersion effect of slurry improve the limited firing property for leading to coating without
Method is improved, when the additive amount of ethyl oleate is more, in sintering process the volatilization of dispersant make coating generate stomata, influence
The resistance of coating.Coating is fired in aluminum alloy surface using spray coating method, the coating layer thickness of generation is 10-14 μm, and coating causes
It is close, it is tightly combined with matrix.
Preferably, step (4) firing is first dried in air, it is burnt into vacuum or inert atmosphere.
Further preferably, drying temperature is 100-150 DEG C when firing, and firing is specially：By room temperature in 1-1.8h
To 550 DEG C, 1-5h, then natural cooling are kept the temperature.
Using the two-step method processing that first drying is reburned, the combination degree of protective layer and alloy surface can effectively be avoided to drop
It is low, while being not easy to crack in firing.
Compared with prior art, the invention has the advantages that：
(1) the special addition Nanoalloy particle of the present invention helps to improve mealy structure attribute.
(2) since the grain size of amount of powder is larger, it is difficult to combine closely, using chemical method by Pd-Pt seed fillings in seam
In gap, and then grows up and be combined.
(3) present invention has fired coating using spray coating method in aluminum alloy surface, and the coating layer thickness of generation is very thin, and coating
Densification is tightly combined with matrix.
