Abstract
Description
Technical Field
[0001] This invention belongs to the field of wear-resistant equipment technology, and particularly relates to a three-dimensional weavable high-performance reinforcement and its preparation method. Background Technology
[0002] Mining machinery, power plant coal mills, and cement plant equipment require a large amount of wear-resistant materials. Wear-resistant parts such as grinding rollers usually work in relatively harsh environments, mainly crushing materials through extrusion and grinding. During operation, they are subjected to extrusion force, impact force, and shear force, which can damage the surface of wear-resistant parts while crushing hard materials.
[0003] Ceramic-metal wear-resistant composites combine the high specific strength, high wear resistance, and high thermal stability of ceramics with the impact resistance and good ductility of metals. Grinding rollers and discs made from ceramic-metal wear-resistant composites can have a service life 2.5 to 3 times that of traditional high-chromium cast iron wear-resistant parts, saving costs and significantly improving production efficiency. However, the poor wettability between ceramics and metals presents significant challenges when using infiltration methods to prepare wear-resistant ceramic-metal composites. Although domestic researchers have conducted extensive research in this field, the results have not been ideal. Currently, China mainly relies on imports for large composite grinding rollers, hammers, and other wear-resistant composite components.
[0004] Imported materials typically consist of ceramic or high-performance alloy particles, which are then bonded together with adhesives to form a prepolymer. This prepolymer is then sintered in an oxidizing atmosphere or under vacuum to enhance its strength and prevent it from collapsing during the casting of the metal matrix. However, this manufacturing process requires high precision, necessitating sintering not only during prepolymer preparation but also again in an oxidizing atmosphere after the prepolymer is formed, resulting in high costs. Summary of the Invention
[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a three-dimensional weavable high-performance reinforcement and its preparation method.

The cubes have through holes for connection when connecting the cubes. Each cube surface has grooves or protrusions of matching shape for connection when fastening, forming a reinforcing body with a three-dimensional structure.

[0016] As a preferred option, such as Figure 8 As shown, the reinforcing particle is an expandable module composed of three cubes; the surface of the cube has grooves or protrusions for connecting the particles, and through holes are provided on the cube. The shapes of the protrusions and grooves match each other for interlocking during the bonding and fixing process, forming a reinforcing body with a three-dimensional structure.
[0017] Preferably, the surface of the reinforcement is coated with a nickel layer, a titanium layer, a cobalt layer, a copper layer, or a chromium layer, and the thickness of the coating layer on the surface of the reinforcement is 5 to 50 μm.
[0018] The method for fabricating this three-dimensional programmable high-performance reinforcement includes the following steps:
[0019] Step 1: Weigh the raw material powder according to the percentage of each component in the three-dimensional braidable high-performance reinforcement to be prepared; ball mill the raw material powder to a D50 of 0.5-1.2 μm (median particle size), mix evenly, dry and pour out as raw material for later use.
[0020] Step 2: Add paraffin wax and oleic acid to the heating pot. After the paraffin wax and oleic acid melt at high temperature, slowly add the raw materials to the heating pot and stir quickly until the powdered raw materials are evenly dispersed in the paraffin wax and oleic acid mixture. Pour the paraffin wax and oleic acid mixture containing the raw materials into a tray and cool to obtain a wax cake.
[0021] Step 3: Add the wax cake to the die casting machine and heat it to melt. Then, draw a vacuum and remove the air. Place the mold on the die casting machine and pressurize the air to send the slurry into the mold. After cooling, demold to obtain a three-dimensional weavable high-performance reinforced blank product.
[0022] Step 4: First, remove the wax from the blank product of the three-dimensional weavable high-performance reinforcement, then send it into the sintering equipment for sintering, and cool it to obtain the reinforcing particles of the three-dimensional weavable high-performance reinforcement.

[0027] The reinforcing particles used in this invention are relatively regular and can be fixed by threading metal wires or high-temperature ceramic fiber ropes to obtain reinforcements of different shapes. Due to the use of reinforcing particles, the porosity of the reinforcement is increased. In addition, the threading and fixing method can be used to weave reinforcements of different shapes with three-dimensional structures, which makes it easy to adjust the particle size of the reinforcement and the ratio of reinforcement to metal. It is easy for manufacturers to design according to their needs and can provide reinforcements on demand, thereby improving the preparation efficiency of three-dimensional weavable high-performance reinforcements.

The connectors used to connect the reinforcing particles can be cylindrical or other shapes, optimized according to actual needs; this invention can connect the reinforcing particles according to shape requirements, and the length of the reinforcing particles determines the porosity of the reinforcing material.

[0065] Step 2: Add paraffin wax and oleic acid to the heating pot. After the paraffin wax and oleic acid melt at high temperature, slowly add the raw materials to the heating pot and stir quickly for 1 hour until the powdered raw materials are evenly dispersed in the paraffin wax and oleic acid mixture. Pour the paraffin wax and oleic acid mixture containing the raw materials into a tray and cool to obtain a wax cake.
[0066] Step 3: Add the wax cake to the die casting machine and heat it to melt. Then, evacuate the vacuum for 10 minutes to remove the air. Place the mold on the die casting machine and pressurize the air to send the slurry into the mold. After cooling, demold the mold to obtain the zirconia toughened alumina ceramic blank.

Pour the paraffin wax and oleic acid mixture containing the raw materials into a tray and cool to obtain a wax cake.
[0079] Step 3: Add the wax cake to the die casting machine and heat it to melt. Then, evacuate the vacuum for 10 minutes to remove the air. Place the mold on the die casting machine and pressurize the air to send the slurry into the mold. After cooling, demold the mold to obtain the tungsten carbide blank product.
[0080] Step 4: First, remove the wax from the tungsten carbide blank, then send it into a vacuum furnace or atmosphere protection furnace for sintering at 1650-1750 degrees Celsius, and cool it to obtain tungsten carbide reinforced particles.
[0081] Step 5: According to the shape of the cast steel product and the required shape of the reinforcement part, pass the metal wire or high-temperature ceramic fiber rope through the through hole on the tungsten carbide reinforcement particle. The tungsten carbide reinforcement particle is fixed by the metal wire or high-temperature ceramic fiber rope to obtain a reinforcement with a three-dimensional structure of the required shape.
[0082] Step 6: Coat the surface of the reinforcement obtained in Step 5 with nickel, titanium or chromium to obtain a nickel layer, titanium layer or chromium layer, which helps to improve the wettability of the reinforcement with molten steel, make it easier to cast and improve the bonding force. The composition and performance parameters of the three-dimensional programmable high-performance tungsten carbide reinforcements in the four examples are shown in Table 2 below.
