Overview of Vacuum Coating Materials And Technologies
Vacuum sputter coating. It refers to the technique of using ions generated by an ion source, which are accelerated and gathered in a vacuum to form a high ion beams, to bombard the surface of the target (coating material), where kinetic energy is exchanged between the ions and the atoms on the surface of the target, causing the atoms on the surface of the target to leave and be deposited on the surface of the substrate material. The object bombarded with ions is the raw material for the deposition of thin film materials by the vacuum sputtering method and is called a sputtering target.

Application and preparation method of spherical powder
Spherical powders have been widely used in many fields because of their good fluidity and high density. In the field of thermal spraying, the spherical powder makes the coating more uniform and dense because of its good fluidity, so the coating has better wear resistance; In the field of powder metallurgy, the forming parts prepared by spherical powder have high density and uniform shrinkage in the sintering process, so the products obtained have high precision and good performance. It has obvious advantages in the application of advanced powder metallurgy forming technology such as injection molding, gel injection molding and additive manufacturing (such as 3D printing technology).

Application of friction stir welding
Friction stir welding is a solid-state connection method. In terms of connection principle, for the metal materials to be connected, as long as the material has a stirring head material that can work effectively in the forging state, the friction stir welding method can be used. to connect.

CT machine X-ray tube anode rotating target
When the CT tube is working, the anode target produces X-rays under the bombardment of high-energy electron beams, but the energy conversion efficiency is very low. Only about 1% of the energy is converted into X-ray energy, and the remaining 99% of the energy is converted into heat energy. The local temperature can be as high as 2600°C. Therefore, the rotating anode target needs to have the characteristics of high high temperature strength, good thermal shock resistance, and fast heat dissipation. Therefore, the density of the target material, the content of alloy impurity elements, and the brazing bonding strength of graphite and molybdenum alloys affect the service life of the target. Key factor.
