Description
Technical field
The present invention relates to a kind of aluminium alloy surface treatment method, especially a kind of 6061 aluminium alloy surface treatment methods.
Background technique
6061 aluminium alloys because its density is small, thermal conductivity is good, specific strength is high, low in cost, easy processing molding the advantages that due to by
It is widely used in the fields such as space flight and aviation, automobile device.But during actual application is on active service, aluminium alloy is asked there is also many
Topic.Such as；Hardness is lower, wear no resistance, be also easy to produce plastic deformation etc. largely limit the application of aluminium alloy.Therefore it is badly in need of
A kind of coating is developed to improve the hardness of 6061 aluminum alloy surfaces and the performances such as wear-resisting, for repairing or strengthening 6061 aluminium alloys,
Very high economic benefit can also be createed simultaneously.
TWIP steel is favored due to its TWIP effect (twinning-induced plasticity) by people, high-intensitive, high-ductility and excellent
Shock resistance and good elongation and be widely used on auto-parts, therefore researched and developed laser melting coating TWIP steel
Coating can preferentially generate twin deforming biggish region, twin boundary hinders dislocation because the stacking fault energy of TWIP steel is relatively low
It slides and causes dislocation pile up, the intensity of material is caused to increase, bigger stress, amount of twin are needed when deformation continues
It will increase, intertwine with each other and complete a business transaction between different twins, further improve the intensity of regional area, meanwhile, deformation can be to low
Strain region transfer, to postpone the formation of constriction；Secondly it in deformation process, can be generated inside austenite grain a large amount of
Deformation twin, these deformation twins constantly cut austenite grain, and commonly referred to as " dynamic Hall-Petch " effect, i.e. fine grain are strong
Change effect, therefore improve the work hardening capacity of material；The deformation twin and austenitic matrix formed in deformation process is in altogether
Case relation, the CSL crystal boundary of this coherence can inhibit the extension of crackle, be conducive to the uniform elongation for improving material.In cladding
The Al in substrate can be spilt in coating in the process, because Al element is austenite former, can inhibit cementite while cooling
Formation, the stacking fault energy of steel can be improved, to inhibit γ → ε phase transformation, and be conducive to the formation of deformation twin, improve steel
Intensity and plasticity, while Al can also reduce the density of steel, and be easy to form the Fe- of high density Dispersed precipitate in austenitic matrix
AlB2 type Second Phase Particle also obtains high strength-to-density ratio while increasing coating spread.
But existing 6061 current aluminum alloy surface modified coatings are mostly acieral, this is because the fusing point of acieral
It is lower, it is close with the fusing point of 6061 aluminum alloy base materials, the damage for easily causing 6061 aluminum alloy base materials is not allowed in laser cladding process
Wound.And higher melting-point alloy coat (steel coating as described in the present application) is then difficult to be applied by the method for laser melting coating
On the surface of 6061 aluminium alloys, this is because the luminance factor of aluminium alloy is larger in actual cladding process, thermal conductivity ratio compared with
Height, surface are easily oxidized, and the fusing point of aluminium alloy is relatively low, therefore the bad regulation in cladding interface, will appear sawtooth in combination interface
Shape.
Based on this, this project researcher from allotment TWIP steel formula and change melting and coating process combination angle,
A kind of 6061 novel aluminium alloy surface treatment methods are developed, can be made in 6061 aluminum alloy surface cladding TWIP steel coatings
6061 aluminum alloy surfaces have better physical and chemical performance, while not damaging 6061 aluminum alloy base materials again.
