Description
Technical Field
The invention belongs to the field of laser additive manufacturing, and particularly relates to a method for preparing a titanium alloy part based on a selective laser melting technology.
Background
The 3D printing technology breaks through the idea of the cutting machining or material forced forming principle of the traditional manufacturing technology, adopts a novel additive forming idea, and can realize the forming of the material by a discrete accumulation method from bottom to top layer by layer without the need of a traditional die and machining. Compared with the traditional machining method, the 3D printing technology mainly has the following advantages: (1) the forming process is more flexible, the support of a tool clamp or a die is not needed, the forming method is particularly suitable for forming workpieces with complex structures, and the requirements of small-batch production and personalized customization of special workpieces can be met; (2) the net forming or near net forming of the material can be realized, and the utilization rate of the material is improved; (3) the 3D printing technology has high forming efficiency and short production period, greatly reduces the production cost, and is convenient for realizing informatization control in the forming process; (4) because the energy density of the laser heat source is high, the 3D printing formed part undergoes the rapid melting/solidification process, the non-equilibrium solidification characteristic promotes the optimization of the performance of the part, and further a fine, uniform and rapid solidification structure with excellent comprehensive mechanical properties is formed, which is superior to the formed parts of the traditional forging, casting and other processes; (5) the application range of the processing material is wide, and some high-melting-point metals, alloys, ceramic materials and the like which are difficult to process by the traditional processing method can be formed by the process.
The Selective Laser Melting (SLM) technology, as a typical 3D printing process, is developed on the basis of the Selective Laser sintering technology, which realizes complete densification of a formed part and further improves its comprehensive mechanical properties. The selective laser melting technology adopts a complete melting mechanism of powder, and reasonable laser process parameters are selected to completely melt the metal powder particles of the newly laid layer and partially melt the deposited layer, thereby realizing good metallurgical bonding between layers. Currently, this technique has been used to form a variety of metals such as nickel-base superalloys, titanium alloys, die steels, stainless steels, and the like.
The titanium alloy as one of the main structural materials in the fields of aviation and aerospace has a series of advantages of low density, high specific strength, good corrosion resistance, low thermal conductivity, no toxicity, no magnetism, weldability and the like, so that the titanium alloy 3D printing technology is successfully used for directly forming small precise components and large complex components in aerospace engines. As early as 1997, the american Sandia national laboratory proposed the idea of using laser additive manufacturing to form titanium alloy components and used laser melt deposition techniques to produce the first Ti6Al4V titanium alloy engine blades. In 2012, the research and application of additive manufacturing technology made several significant progress. Such as NASA, use selective laser melting techniques to make metal parts and plans to use the techniques for making J-2X engine parts. The Sciakv company in the United states is in international leading position in the electron beam additive manufacturing technology and equipment research of large titanium alloy components. In recent years, China also makes great progress in the research aspect of titanium alloy 3D printing technology, but in the processing process of titanium alloy parts, complex chemical reaction occurs in a molten pool, and an input heat source has obvious influence on forming quality and momentum change, for example, powder raw materials (granularity, fluidity, sphericity and the like) and laser parameters (laser power, scanning speed, scanning interval and the like) have important influence on the forming parts. Therefore, the powder material is melted and solidified inevitably to cause structural defects such as air holes, cracks, residual stress and the like in the formed part, and further, the comprehensive mechanical properties of the formed part and the stability and reliability of use are affected, so that the control of the powder material and laser parameters is important in order to obtain the titanium alloy part with excellent structure and performance.
Disclosure of Invention
Aiming at the defects of air holes, cracks and the like in the forming process of the titanium alloy part in the prior art, the invention provides a method for preparing the titanium alloy part based on a selective laser melting technology.
The purpose of the invention can be realized by the following technical scheme:

1) selecting spherical titanium alloy powder with good fluidity as a raw material;
2) constructing a part model to be prepared by using three-dimensional software, carrying out two-dimensional slicing on the model, and then guiding the model into selective laser melting molding equipment;
3) setting processing technological parameters of the selective laser melting processing process, and performing laser processing;
4) and carrying out linear cutting, cleaning and sand blasting on the printed part to obtain the titanium alloy part.
In one embodiment of the invention, the titanium alloy is Ti6Al 4V.
The Ti6Al4V powder for selective laser melting forming comprises the following components: al: 5.5-6.75%, V: 3.5% -4.5%, Fe: less than or equal to 0.3 percent, C: less than or equal to 0.08 percent, N: less than or equal to 0.05 percent, H: less than or equal to 0.012 percent, O: less than or equal to 0.13 percent, Ti: and (4) the balance.

The powder with the particle size of less than 15 microns is the main reason of low powder flowability, the proportion of the Ti6Al4V powder for selective laser melting is reduced by air classification, but the laser sintering is facilitated due to the fact that the specific surface area of the fine particle powder is large and the sintering driving force is large, meanwhile, the gaps of the formed part can be reduced due to the fact that the fine particles are filled into the gaps of the large particles, the density and the strength of the formed part are improved, and therefore a part of the fine particle powder needs to be reserved. The powder with the particle size larger than 53 μm is a main cause of rough surface and poor forming precision of the laser melting formed part in the selected area, so the content of the powder with the particle size larger than 53 μm needs to be controlled.
In a preferred embodiment of the invention, the Ti6Al4V powder for selective laser melting forming has a flowability of 45s or less.
Powder fluidity is a key factor influencing the quality of the selective laser melting molded part, and is poor in powder laying fluidity, so that the powder laying layer thickness in certain areas is uneven, more splashes are generated during laser sintering, and the defects of cracks, unfused powder and the like are easy to occur in the molded part.

The selective laser melting process is a process of quickly acting a high-energy laser heat source and metal material powder, the powder material is quickly melted and solidified in a short time by quick heating and cooling, great thermal stress can be caused between the material forming area and the formed area, if the laser processing parameters of the part are not properly selected, surface cracks can be caused to the part, and once the macrocracks are generated, the practicability of the part is greatly limited. Therefore, in the selective laser melting forming process of the parts, the laser processing technological parameters need to be strictly selected, and the formed parts with few defects and high comprehensive mechanical properties are obtained.
In one embodiment of the invention, in the step 3), argon is introduced into the forming cavity as a protective gas during the processing process, so that the oxygen content in the forming cavity is not more than 0.1%.
In one embodiment of the present invention, in the step 3), the substrate preheating temperature is set to 20 to 50 ℃.
In one embodiment of the invention, in the step 4), the wire cutting is performed by using a reciprocating wire-cut electric discharge machine, and the wire is cut at a speed of less than 10 mm/s.
In one embodiment of the invention, in the step 4), the cleaning is ultrasonic cleaning, the cleaning medium is an organic solvent and absolute ethyl alcohol, and the cleaning time is not less than 0.5 hour.
