What is the melting of an electron beam?
Electron beam melting (EBM) is a technique in which part of the machine is made by a layer of melting on the powder layer to form the desired shape. This rapid production method uses an electron beam in the vacuum to produce the necessary temperature to melt the powder. Parts designed in this way are usually remarkable for having more desirable physical properties than parts constructed with other methods.
To create a component by melting the electron beam, the material to be processed is placed in a vacuum chamber. The size of this chamber determines the maximum possible size of the finished part. The electrons are then emitted from the fiber and accelerate to approximately half the speed of light. The magnetic fields focus and direct the beam to the necessary places. When electrons collide with powder particles, their kinetic energy is transformed into thermal energy, thus warming the powder.
Because the beam affects only a very shallow area to the surface ofAbout the layer. Computers are usually used to control the location and time of the beam, even if the operator oversees this process. The three -dimensional design schemes supporting computer provides dimensional information necessary to control the beam.
EBM is often referred to as a type of rapid production method known as additive production. Such processes provide an accurate amount of energy and material to accurate places for the development of the desired structure. Rather than using the form to define the shape of the part, additive manufacturing techniques use a three -dimensional digital plan to specify its shape.
metals are the most typical materials used to design components with electron beam melting. Sometimes, however, other materials such as ceramics and ceramic metal composites are also used. The melting of the electron beam is particularly suitable for use with materials that react with oxygen because the production of probesIt is in the vacuum chamber.
There are a number of advantages with the melting of the electron beam. Due to high energy, this technology allows high melting capacity and high productivity. EBM can produce components of extremely complex geometry. The resulting parts are generally known for their extremely high density and lack of cavities in the structure.
Extremely high temperatures, usually connected to the process, often produce metal parts with similar metallurgical characteristics as thermal components. For example, products of this method generally have higher strength and small or no residual voltage compared to products of other manufacturing methods. This often shortens the production time by avoiding further heat treatment operations after creating the work.
Components made with electron beam melting are located in a wide variety of applications. Its suitability for use with reactive titanium alloys means that the melting of an electron beam is often used to construct light titAnni components such as medical implants. Known for the production of parts of high strength and good metallurgical quality is also often used to produce high -performance parts. For example, it is used to produce such items such as turbine blades for air applications and vehicle frames used in motor sports.
