In the forming process, the aluminum molten drops and the particle reinforced phase are jointly sent into an electric arc molten pool, along with the movement and solidification of the electric arc molten pool, the particle reinforced phase can be dispersed in the aluminum matrix to form the composite material component in a way of gradual/layer-by-layer accumulation, and finally, the high-quality, high-efficiency and low-cost additive manufacturing of the aluminum alloy/particle reinforced aluminum matrix composite material component is realized.
Description
Technical Field
The invention belongs to the technical field of additive manufacturing, and particularly relates to a device and a method for manufacturing a particle reinforced aluminum matrix composite material by a molten drop composite electric arc additive.
Background
The additive manufacturing (also called 3D printing) technology is a non-traditional processing technology, and is an advanced manufacturing technology integrating light, electricity, electromechanics, computers, numerical control and new materials, which arose in the 90 s. The core idea is to perform two-dimensional dispersion on a three-dimensional part to form lamellar data, gradually combine discrete forming materials together according to the layered data of a three-dimensional CAD model of the part to form layered sections, and then pile up layer by layer to form a solid part, without a die, directly manufacture the part, and can greatly shorten the development period.
According to the form of a heat source, the mainstream metal additive manufacturing method is mainly divided into selective laser melting, selective electron beam melting, laser (melting) deposition and arc (melting) deposition. The mainstream metal additive manufacturing method can be divided into powder laying forming, powder feeding forming, wire feeding forming and droplet forming according to the raw material form.
At present, additive manufacturing modes suitable for rapid forming of aluminum-based components mainly comprise selective laser melting, selective electron beam melting and arc (melting) deposition. In view of the characteristic that an aluminum alloy molten pool is extremely easy to oxidize, the laser (melting) deposition technology is difficult to ensure the bonding strength between layers of the aluminum-based component, and the solid laser (melting) deposition technology is not suitable for forming the aluminum-based component. The arc heat source, especially the variable polarity arc heat source, has special cathode cleaning function to break and clean the oxide film on the surface of the aluminum alloy molten pool, so as to ensure high-quality metallurgical bonding between layers. Meanwhile, the arc heat source has high melting efficiency, and is beneficial to realizing high-efficiency additive manufacturing of the aluminum-based component.
Because the aluminum alloy has the advantages of low density, high specific strength, high thermal conductivity, wide sources and the like, the aluminum alloy plays an extremely important role in the industrial field and the daily life field of people. However, the aluminum alloy has low surface hardness and poor friction and abrasion resistance, so that the application of the aluminum alloy in occasions with specific requirements on abrasion resistance is greatly limited. Therefore, the ceramic particle reinforced aluminum matrix composite material technology becomes a key technical route for solving the problem of insufficient wear resistance of the aluminum alloy. The ceramic particles have an extremely high hardness and thus have excellent frictional wear resistance.
The existing additive manufacturing scheme of the particle reinforced aluminum matrix composite material mainly comprises three types: the manufacturing method comprises a high-energy beam (laser and electron beam) selective melting additive manufacturing technology based on a nanoparticle reinforced aluminum-based composite powder technology, an arc additive manufacturing technology based on an interlayer ceramic particle coating technology and an arc fuse additive manufacturing technology based on a composite wire manufacturing technology. In the first technique (high-energy beam selective melting additive manufacturing technique based on the nanoparticle reinforced aluminum-based composite powder technique), the abrasion resistance of the aluminum matrix is not significantly improved due to the low mixing ratio of the nano ceramic particles and the small (nano) particle size of the high-hardness ceramic particles. Meanwhile, the forming efficiency of the high-energy beam selective melting additive manufacturing technology is low, so that the forming requirement of medium-large aluminum-based components is difficult to meet. The second technique (arc additive manufacturing technique based on interlayer ceramic particle coating technique and arc fuse additive manufacturing technique based on composite filamentation technique) has limitations in that the forming efficiency is low and the thickness of the strengthened layer is small. The high efficiency advantage of arc deposition is greatly reduced because the interlayer coating process requires each layer to be cooled to near room temperature and the next layer of deposition must ensure complete volatilization of the solvent components in the mixture applied to the surface of the deposited layer. The main limitation of the third technique (arc fuse additive manufacturing technique based on composite wire manufacturing) is the preparation of special wires. Compared with the traditional welding wire, the plasticity of the aluminum-based material compounded by the ceramic particles is usually obviously reduced, so the technical difficulty of wire making is solved.
Disclosure of Invention

The molten drop composite electric arc additive manufacturing system replaces a wire feeding mechanism in a traditional electric arc fuse additive manufacturing system by an independent molten drop generating system, so that a material adding link and a heat input link in the electric arc additive manufacturing process can be independently regulated and controlled. The introduction of the molten drop generating system can overcome the defect of strong wire-arc coupling inherent in the traditional electric arc fuse wire additive manufacturing technology, and has important significance for further improving the electric arc additive manufacturing efficiency and quality. Meanwhile, a reinforced particle powder feeding device is introduced into the particle reinforced aluminum matrix composite droplet composite electric arc additive manufacturing device provided by the invention, and the device can implant reinforced particles into an electric arc molten pool in a powder-carrying manner, so that the electric arc additive manufacturing of the particle reinforced aluminum matrix composite is realized.

The water cooling design can ensure that a sensing device arranged on the water cooling top cover is at a safe working temperature; the water-cooling top cover is provided with an air inlet/outlet which can charge air or exhaust air to the interior of the molten drop generating system so as to achieve the purpose of pressurization or depressurization; a material adding inlet is designed on the water-cooling top cover, so that metal materials can be added into the molten drop generating system in the forming process, and the added materials include but are not limited to small-size blocks, small-size bars, wires and powdery materials, so that the requirement of continuous forming of medium-size and large-size parts or the requirement of adjusting the chemical components of the materials in the forming process can be met.
Furthermore, the water-cooling top cover is provided with a pressure sensor and a laser distance sensor so as to realize real-time measurement of the air pressure in the crucible and the liquid level of the melt in the crucible and feed back real-time data to the air pressure driving system. After receiving the air pressure information and the melt liquid level information, the air pressure driving system can further calculate the pressure of the melt at the bottom of the crucible, so that the accurate control of the air pressure driving system on the pressure at the bottom of the crucible is realized.
Furthermore, a top cover radiating fin is arranged between the lower part of the water-cooling top cover and the smelting crucible, and a high-temperature sealing ring is arranged between the top cover radiating fin and the smelting crucible. The arrangement of the top cover radiating fins can prevent excessive heat from being taken away through the water-cooling top cover. When the temperature of the crucible rises, the threaded connection part between the melting crucible and the radiating fin is loosened due to the difference of the thermal expansion coefficients of the materials, and the high-temperature sealing ring has the function of generating axial expansion after the temperature rises, so that reliable high-temperature sealing between the top cover radiating fin and the melting crucible is realized. And the periphery of the smelting crucible is provided with an induction heating coil for realizing the induction heating of the metal material in the smelting crucible.
Furthermore, a filtering flange is arranged at the bottom of the smelting crucible, and a ceramic filter is arranged between the smelting crucible and the filtering flange.

The bottom of the filtering flange is provided with a switching flange, a flow control assembly is arranged between the filtering flange and the switching flange, the flow control assembly, the filtering flange and the smelting crucible are arranged in a laminated mode. The laminated arrangement has the advantages that the sealing surfaces between the parts can obtain similar pretightening force, the sealing is reliable, the assembly is simple and convenient, and the complementary tightening of the sealing surfaces in a high-temperature state is facilitated. The bottom of the adapter flange is connected with the spray head, a heating sleeve is arranged outside the spray head, and the heating sleeve is electrically connected with the temperature controller. The adapter flange has the advantages that the connection mode is changed, the upper part of the adapter flange is in bolt connection (the smelting crucible, the filtering flange, the flow control assembly and the adapter flange form a whole), and the lower part of the adapter flange is in threaded connection, so that the nozzle is convenient to install and replace. The heating sleeve aims at realizing the heating of the spray head, and the temperature controller is used for controlling the heating process.

The design of the temperature measuring hole is used for measuring the temperature of the melting crucible and the spray head, and the thermocouple does not need to be contacted with the aluminum alloy melt in the melting crucible in the temperature measuring process, so that the pollution of the aluminum alloy melt and the corrosion of a temperature measuring element (thermocouple) caused by temperature measurement are avoided. The temperature controller collects thermoelectric potential difference from the crucible thermocouple and the nozzle thermocouple in real time and converts the thermoelectric potential difference into temperature information, so that the heating process of the induction heater and the heating sleeve is controlled.
Furthermore, the flow control assembly comprises a flow passage inlet protection plate and a flow passage outlet protection plate, and a labyrinth flow control plate is arranged between the flow passage inlet protection plate and the flow passage outlet protection plate. The runner inlet protection plate, the runner outlet protection plate and the labyrinth flow control plate are arranged in a laminated mode, and a runner surrounded by the runner inlet protection plate, the runner outlet protection plate and the labyrinth flow control plate is a labyrinth runner. The labyrinth runner has a periodically bent runner structure, so that the internal friction energy consumption of viscous fluid (aluminum alloy melt) can be obviously increased, and further smaller jet flow can be obtained under the same driving pressure, or the driving pressure can be obviously increased under the same jet flow. Meanwhile, the labyrinth flow passage has the effect of maintaining the flow stability. In the melt jet process, small holes at the tail end of the spray head are easy to block, when the flow is reduced due to the blocking of impurities, the flow velocity of the melt in the labyrinth runner is reduced, and the lost flow field kinetic energy is converted into static pressure energy, so that the melt in the small holes at the tail end of the spray head is forced to flow in an accelerated manner. The accelerated melt is favorable for taking away the blockage adhered to the hole wall, thereby being favorable for recovering the jet flow to a normal value.
Furthermore, an inlet sedimentation tank is arranged on the flow channel inlet protection sheet, and the bottom surface of the inlet sedimentation tank is obviously lower than the upper edge of the flow channel inlet. The inlet sedimentation tank is used for accommodating indissolvable particulate impurities with the density larger than that of the aluminum alloy melt and preventing excessive particulate impurities from entering a labyrinth flow channel through a flow channel inlet.
Furthermore, the reinforced particle powder feeding device comprises a powder feeder, the powder feeder is connected with a powder feeding nozzle through a powder feeding pipe, and the powder feeding nozzle is fixed on a ceramic protection nozzle of the arc welding torch through a powder feeding nozzle clamp.

A composite material design step is added between model design and shaping path planning, and is used for determining the selection type of the matrix material and the reinforcing particles and the reinforcing particle implantation proportion in the composite material in the design planning stage. In the forming preparation step, the forming environment requirement is included, and for the drop-on-fuse composite arc additive manufacturing of the easily-oxidized material, the forming process needs to be ensured to be in an inert atmosphere environment with low water and low oxygen. Meanwhile, in the forming preparation step, the tightness detection after the raw material filling and the molten drop generating system are assembled is standardized. In the two steps of heating and droplet generation system function verification, heating parameters are standardized, and after the heating is carried out to a preset temperature, all function verification processes of the droplet generation system are standardized, including basic function verification such as pressure detection, air pressure loading, laser liquid level measurement and the like and function verification of jet flow state and jet flow, and the method is used for ensuring that a key system droplet generation system can normally run in a later forming stage. The main objects of process monitoring are specified in the forming process monitoring step: macroscopic shape and overlapping defects, the former is used for ensuring the forming precision, and the latter is used for ensuring the overlapping quality macroscopically. After the forming and post-processing steps are completed, a quality detection step is added subsequently, and the detection link comprises the dimensional precision, the density, the internal defects, the microstructure and the mechanical property, so that the delivered parts can meet the requirements on manufacturing precision and quality.
