Description

A kind of metal laser melting increasing material manufacturing method
Technical field
The invention belongs to material increasing field, and in particular to successively laser fusion increasing material manufacturing and constituency agitating friction are compound Technology, can realize flawless, nanocrystalline, high-toughness metal parts manufactures.
Background technology
Laser fusion increases material manufacturing technology, is to develop first system a kind of faster in recent years also known as laser fusion 3D printing Make technology.The laser fusion increases material manufacturing technology of metal parts is by high energy laser beam successively fusing metal powder, Jin Ershi The manufacture of existing arbitrarily complicated metal parts, but still suffer from following technical bottleneck：
First, the features such as there is fast hot rapid cooling, high gradient Re-power-stream multi- scenarios methods due to laser gain material manufacturing process, lead Cause laser gain material manufacture part memory in thermal stress higher, form crackle.When tensile strength of the tension more than cladding layer, Stress concentration easily is produced in stomata, Flat Inclusion Tip etc., so as to form crackle.Crackle is laser gain material manufacture or even laser A kind of defect being widely present in manufacture field.Produced for crackle, domestic and foreign scholars are from theoretical modeling, Germicidal efficacy, tissue Analysis isogonism have studied the stress field and crackle mechanism of production of laser melting process, it is proposed that the method for reducing crackle：（1）Powder bed Preheating；（2）Addition alloying element, netted foil carry out toughness reinforcing with plasticising；（3）Ultrasonic activation.Above method is to a certain degree On reduce stress concentration and tearing tendency, for propulsion Laser Processing development serve positive role.However, because laser is molten Pond process of setting is extremely complex, and above-mentioned resistance cracking method still suffers from certain limitation：First, above method is difficult to that fine fisssure is completely eliminated Line, especially for the crack-sensitivity material high such as Ni-based, cobalt-based；Secondly, above method is difficult to general applicability.
Second, the brittle ceramic phase in iron-based, Ni-based and cobalt-base alloys laser gain material manufacture tissue（Such as M7C3, M23C6）Hold Easily with continuous net-shaped structure distribution around matrix grain, the obdurability of laser gain material manufacture is greatly reduced.Although ceramic The presence of phase can significantly put forward the hardness and wearability that laser gain material manufactures part, but the ceramic phase of these network-like distributions will Metal grain is isolated from each other and comes, and largely reducing intercrystalline adhesion, causes laser gain material to manufacture part integrity energy table It is now fragility, when laser gain material manufacture part is on active service under external load function, stress is difficult to transmit, and then crackle can be caused to sprout It is raw to be failed with workpiece.However, not yet there is the removing method of this net carbide of literature research.Although heat treatment can be certain Carbide content and segregation are reduced in degree, but is difficult to change completely the continuous net-shaped distribution of thick-layer carbide, on the other hand, Heat treatment cannot eliminate microfissure.
3rd, laser gain material manufacture forming process is also easy to produce nodularization and hole, largely effects on laser gain material and is manufactured into The mechanical property of shape effect and drip molding, is still the major defect of laser gain material manufacture part, and material is increased as forming laser The bottleneck problem of manufacturing technology, influence laser gain material is manufactured toward high-performance metal part application.
The above analysis, micro-crack, ceramic phase net distribution, nodularization existing for common laser gain material manufacture part, Pore problem is that obstacle is provided with the technology way forward.Although domestic and foreign scholars carried out research simultaneously regarding to the issue above Positive progress is achieved, but synchronously realizes the elimination of laser gain material manufacture part crack, ceramic phase Dispersed precipitate, tissue nanosizing Method do not grasped completely yet so far.
Mixing yoghurt（Friction Stir Processing, FSP）It is a kind of new become by surface plasticity Method of the shape to improve tissue, makes workpiece surface temperature raise rapidly, metal by mobile stirring-head and workpiece severe friction Plastify, mixing needle agitation skin-material makes it produce plastic flow and mixing, and the shaft shoulder is the material by mixing needle agitation deformation Material is transferred to stirring-head rear side and applies forging effect simultaneously.Due to the material in FSP processing districts generate severe plastic deformation, Mixing, broken and heat exposure, so as to can realize that the crystal grain refinement of metal material microstructure, nanosizing, crackle are eliminated.The processing Method and laser fusion increases material manufacturing technology are combined there is presently no relevant report.
