Description of the Invention: [Technical Field] The present invention relates to a molding method and molding apparatus for fabricating a cermet workpiece, and a cermet composite structure. And in particular, the present invention relates to a molding method and molding apparatus for producing a cermet workpiece by dehydration, and a cermet composite structure. [Prior Art] Composite materials can be divided into three categories: P〇lymer Matrix Composites (PMCs), Metal Matrk Composites (MMCs), and Ceramics Matrix Composites (CMCs). . The traditional methods for manufacturing metal-ceramic composites include: infiltration method, dispersion method, powder metallurgy method, diffusion bonding method, and the like. However, composite material workpieces can also be fabricated using Rapid Prototyping (RP) technology. Rapid prototyping technology uses layered processing technology to automatically create 3D solid objects in accordance with the CAD geometry. It can overcome the geometric dead angle that can not be completed by tool machining, and it can automatically make Solid Freeform Fabrication (SFF), and the prototype made has no shape limitation. There are currently three types of cermet workpieces produced using rapid prototyping techniques. One is to use a Selective Laser Sintering (SLS) technique, such as coating a metal or ceramic powder with a thermoplastic inorganic material to make a cermet workpiece. The other is the use of Fused Dep〇siti〇n Modeling (FDM) technology, for example, using FDM* to make ceramic workpieces with pores, and then infiltrating aluminum metal by infiltration to form a muUite_aluminum cermet Composite material. Another method is to use Three Dimensional Printing (3DP) technology, for example, by using inkjet printing technology to spray on H or metal powder (such as: recording) to connect them, and if it is sticky, it can be made into Metal, ceramic, or metal ceramics. Μ ai, in the above technology, the SLS technology uses a thermoplastic material as a gas that is harmful to the human body when it is post-junction treatment. Application: ? gentleman technology? This will allow a low melting point metal (such as aluminum) to be heated and penetrated into the ceramic workpiece to a limited range of materials. The use of 3DP technology is based on the use of the point ϊ 利 ί ί 陶 粉末 powder, the binder needs to have a good flow of the suppression, bonding, but its poor adhesion, so the strength of its finished product is weak [invention] - (4) It is to provide a method for forming metal-ceramics and a molding device, and a metal-ceramic structure.

Wherein the mixing can be carried out by means of a mixing device. The molding method then coats a layer of slurry on a workbench, 'making the heated fabric = ί another == two layers for gold::= double over the above steps, coating another - sound smashing off heat The other layer of the material is stored in an integral number of the thin layer and the _ 陶陶 Ί 374865 ί 2 .

When this mesh is divided into gold = two: the metal powder is coated and = together. After the completion of the gel reaction, a three-dimensional shape is formed; the ceramic transformation is converted into a chemical gel reaction, and the metal powder structure is coated during the chemical gel reaction. (4) The binder is not made, because the ^ paste can be easily removed without special solvent in the process of removing the residual material and the subsequent optional sintering process: i ^ t invention can be heated by laser The secret of coating is so that the energy required for the Taunu water is much smaller than the amount of sintering, which greatly reduces the effects of shrinkage and deformation. In addition, the above-mentioned ί? slurry can be added to the ceramsite, and the granules can be produced by the laminating process. The present invention has the following advantages over the prior art: 1. The present invention adopts Lamination processing technology to produce cermet composites. 7 (S pass, the method of manufacturing composite materials includes: vapor deposition method, re-gold method, diffusion bonding method, etc., and in the process of transporting the workpiece to the workpiece, (4) using a thermoplastic material to coat the molten metal The person has a pore _ 仏 ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; Si, Si-0-C/SiC, Α1·0_Α1) are further developed to coagulate and bond the metal powder, so that no additional adhesive or metal infiltration treatment is required. 2. The composite strengthening mechanism of the present invention is Particle-reinforced & η * composite materials are often fiber-reinforced, fibers can make ceramic cracks two or two too (10) ^ crack growth to improve strength ' while the invention is based on gold = German material and ceramics as the base. It can improve the expansion of the moving particles to disturb the ceramic fiber's. That is, when the ceramics are === lions, the fineness will be more entangled. 3. The material state used in the present invention is the state of the slurry (4) in the prototype technology. The material state used by SLS and 3DP is solid ϊϊίϊίί 'FDM's shouting The material state is semi-liquid, and the slurry formed by the metal powder and the shuffling is mixed with a certain fluidity, and the thickness of the solid material and the liquid material is thin, so as to improve the precision of the product. The slurry specially makes the metal powder particles and the particles difficult to separate, and can improve the strength of the product. y = This is a disadvantage of the powder in the SLS process after the powder is laid, which causes the strength of the workpiece to be weakened. The gold gamma material has the properties of combustability and wear resistance. .1374865 The general ceramic material has high hardness but high brittleness, and it is easy to crack during the cutting process of the tool, so the cutting process is very poor. The invention adds a metal material (the weight ratio can be up to 75% or more) to the ceramic substrate, so that the machinability can be increased. On the other hand, the composite material of the invention is coated with a ceramic material on the outer layer of the metal particles, so that the ceramic material can be improved. The advantages and spirit of the present invention can be further understood from the following detailed description of the invention and the accompanying drawings.

As shown in steps S104 and S106 of Fig. 1, a layer of the mixed (four) material SL shirt is applied as a coating device by the coating device 12. In a preferred embodiment, the coating apparatus 12 may include a funnel 122 for holding the slurry Sl and a plate 124 (or cylindrical drum) that allows the slurry SL to be hooked and distributed over the working crucible 14. The funnel I22 squeezes the appropriate slurry %' onto the table 14, as shown in step S104. The squeegee 124 applies the aforementioned slurry SL to a uniform thin layer slurry SL as shown in step S1-6. The thickness of the layer of slurry SL can be controlled at about 〇. However, the present invention is not limited to this. The required coating thickness should be based on the design of the finished product and the characteristics of the slurry, that is, the thickness of the coating is variable. Further, the present invention is not limited to coating the slurry in a horizontal or equal thickness. As shown in step S108 in FIG. 1, the layer slurry SL is heated by the heating device 16 according to a specific plane pattern to dehydrate the layer slurry SL, so that the heated ^, _SL' is bonded at (10). It is a thin layer of metal with a specific shape (the dark part in Figure 2B). According to the preferred embodiment, the heating device 16 includes a laser 162 and a lens assembly 164. Laser 162 is a c〇2 laser. The lens set 164 is used to perform a galvanometer meter rr scan comprising two reflective lenses (Fig. 2B is represented by only one element). The lens ^ 164 scans the light emitted by the laser 162 onto the layer of slurry 乩, which heats the layer of slurry SL' in a planar scan to form a cermet solid thin layer, as shown in Figure 2B. According to the preferred embodiment, the scanning rate is from 80 mm/s to 120 mm/s and the laser power is from 30 w to 4 〇w. Further, this heating dehydrates the layer slurry SL' due to the ceramic sol, i.e., the si 〇 2 sol, and X produces a chemical gel reaction. That is, the si〇2 sol will be dehydrated to the si_0_si chain & molecule, '. The structure is further developed into a network of molecular structures. When the growth reaches the end of the metal, the metal powder is tightly coated and bonded together. A metal powder reinforced ceramic matrix composite is formed after the chemical gel is completed. Due to the use of organic binders, no harmful gases are produced during the removal of the remainder and subsequent alternative sintering processes. Please refer to Figure 3. Figure 3 is a SEM photograph of a stainless steel powder and a SiO 2 sol after chemical gelation. According to the preferred embodiment, the Si 〇 2 sol forms a porous base after the condensing reaction, and the coated person is a metal powder (in the form of granules), which enhances the strength of the base. When the porous ceramic base generates 妒t(Crack), the crack grows to the metal powder and is blocked by the material g of the metal powder, especially when the metal powder has an irregular surface. In addition, the 'corrective shouting base itself has poor recording and stress, and borrows ίΤΙίΓ(9) to make it resistant to tensile stress and increase initiality. When the metal powder is in the form of short fibers, the degree of bonding of the wire is better.

In the general case, each layer is given a cross section of the workpiece 2. The heating is set to 16 and the surface pattern is the metal surface pattern corresponding to each layer of the material, dehydration and according to the specific Solid-state thin layer.

In addition, ^ can increase the strength of the thin layer of the metal ceramics by means of junctions, but it is also possible to add materials to the device (for example, soaking tanks) to increase the strength of the thin layers of the metal. _, liquid shouting materials, (4) gold can penetrate into the material infiltrating the metal shouting _ thin layer. For example, the liquid spring ‘Mann material infiltrates these thin layers of gold, in addition to increasing the New Zealand, and also adding the homogeneity of the ceramic workpiece. For another example, a liquid metal is infiltrated into the thin layers of the solid metal ceramics, since the solid thin layers of the cermet have a plurality of pores: the metal can fill the pores to form a network-like solid structure, and the shape is further increased. Metal-ceramic composite structure. In addition, since the liquid metal is infiltrated into the uniformly and randomly distributed voids, the cermet workpiece 2 is increased in an isotropic manner (4).

The fine iron coating determines that the = = "slurry state" has a material, the household of the invention uniformly lays out a thinner thickness to listen to the subsequent heart; the second chemical gel reaction to form a ceramic solution The chemical gel reaction of the hair J is 'growth two: the metality of the double-distributed metal is uniform=The metal-ceramic composite structure with a considerable content of external factors has higher machinability, and the pure ceramic structure of the mouth has a more overlap. Therefore, the wear resistance of the Tao Jing material is still preserved. The details of this embodiment are described by the Tao Xing base at the end of the 4th, and it is hoped that the description will be more clearly defined. On the contrary, the purpose is to hope that 14 can cover all kinds of changes and equals according to the above description, and the scope of the scope should be rooted and _, (10) to cover the possible changes in the financial system.
