Description
Technical field
The present invention relates to metal-base composites to prepare manufacture field and material increasing field, more particularly to a kind of high pass
The device and method that amount prepares metal-base composites.
Background technique
With science and technology greatly develop, the requirement to material property is also higher and higher, existing high intensity, high-modulus,
High temperature resistant, low-density homogenous material be far from satisfying requirement.For this purpose, a large amount of scholar use complex technique both at home and abroad
The Material cladding of different performance is got up, is learnt from other's strong points to offset one's weaknesses, it is superior novel multiple to obtain the incomparable comprehensive performance of homogenous material
Condensation material.Metal-base composites is using metal and its alloy as matrix, with one or more of metals or nonmetallic reinforced phase people
The composite material that work is combined into.Metal-base composites has low coefficient of thermal expansion, high-fire resistance, the high ratio in terms of dynamic structure
Intensity, high ratio modulus, it is wear-resistant and anti-aging the features such as, so favored by people, especially led in automobile, Aeronautics and Astronautics
Domain is widely used.People's metal-base composites during designing and manufacturing often attempts to abide by reinforced phase distribution
Follow certain regulation, rather than uniformity occur in the base, for example graded metal matrix composite, laminated metal base are compound
The assembly (also referred to as mixed metal based composites) of material and a variety of composite materials, to meet some spies in practical application
Different performance requirement.In addition to the performance requirement of multiplicity, different use environments also requires product to be designed to different shapes, this
Challenge just is proposed to the manufacturing process of metal-base composite-material product.
Currently, the common method of industrial batch micro operations complicated shape metal based composites components be model casting,
The processes such as machining and injection moulding.Wherein, model casting will be manufactured, roast and be poured through overvoltage, fusible pattern manufacture, shell
The series of processes such as note, complex process, it is difficult to control.For the multilayered structure of certain complexity, modular structure and pouring and riser systems
Design be also a big difficulty.Machining is then limited mainly due to rapidoprint and complexity, such as hard alloy, tungsten alloy
The higher material of isodensity is increased using the difficulty and cost of machining manufacture.And have the zero of labyrinth for certain inside
Component, machining are difficult to disposably shape, need for components to be split as multiple portions, pass through the method for welding after processing respectively
It connects, further increases duration and cost.Mold is important a ring in injection moulding, however the manufacturing price of mold
It is high and bothersome, and complexity is higher, price and manufacture difficulty are also higher.In addition to this, above-mentioned preparation method is once led to
The metal-base composites that a kind of ingredient can only often be prepared is unable to control reinforcement quantity, distribution and arrangement, and preparation efficiency
It is low, the period is long, be also unfavorable for the research and development of novel metal based composites.
The late 1980s, a kind of collection mechanical engineering, CAD, reverse Engineering Technology, Layered Manufacturing Technology, numerical control skill
The technology of art, material science, laser technology is born, i.e. increases material manufacturing technology (3D printing technique), it solves tradition
Limitation of the processing technology in product shape and manufacture, automatically, directly, quickly and accurately can be changed into phase for design philosophy
The prototype or part answered.Traditional processing manufacturing method is substituted using 3D printing technique, it can be in article shape, cost and production week
Triple breakthroughs are realized on phase.And for metal-base composites, since the exclusive materialization of the diversity and each component of its component is special
Property, existing 3D printing technique are difficult to shape: SLS and SLM technology is bonded in one after making powder melts using laser as heating source
It rises, but since the difference of the performances such as fusing point, thermal expansion coefficient between component makes it be difficult to bonding forming after simply melting；FDM
Technology is only suitable for lower melting-point material, this is even more to be difficult to be applicable in for metal-base composites；Especially for matrix or increasing
Qiang Xiangzhong has the case where refractory compound, and these types of technology is even more to be difficult to meet its temperature requirement.

Step 2): different metal based composites suspension slurry is defeated through slurry under compressed air and the effect of slurry flow control valve
Hose is sent continuously and quantitatively to be transported in each printing head of more spray head drop-on-demand deposition systems, a printing head is used for
A kind of metal-base composites suspension slurry of jet deposition；
Step 3): multiple spray heads selectively layer-by-layer jet deposition various metals based composites suspension slurry, and by drawing
Hair system causes the instant solidification of metal-base composites suspension slurry, realizes the layer-by-layer solid of metal-base composites suspension slurry
It is melted into shape, completes the high-throughput preparation of multi-component complex shaped metal based composites green body；
Step 4): after metal-base composites body drying, degreasing and sintering, fine and close metal-base composites is made.
