Titanium targets play an important role in the high-tech sector, especially in thin film deposition processes. This material is mainly used by magnetron sputtering or physical vapor deposition (PVD) technology to deposit a thin film on a substrate with a specific functional or decorative effect. Titanium targets are made of pure titanium or its alloys with a specific shape and fine surface for physical evaporation or sputtering processes.
There are two main preparation methods for titanium targets: melting casting method and powder metallurgy method. The melt casting method uses vacuum melting technology to melt high-purity titanium raw material and then cast it into an ingot blank. After heat treatment and rolling or hammer forging, the ingot blank is processed by a machine tool to obtain a titanium target. This method is simple and straightforward, but it needs to be performed under a strict vacuum or protective atmosphere, and may have problems such as internal segregation and rough tissue. The powder metallurgy method is a novel method that enables the preparation of homogeneous and defect-free targets, despite the complexity and cost of the equipment.
The application and performance requirements of titanium targets include purity, microstructure, welding performance and dimensional accuracy. Purity is one of the main performance indicators of the target, as it has a significant impact on the properties of the film.
In practical applications, titanium targets are mainly realized by magnetron sputtering or PVD technology. Magnetron sputtering uses a magnetic field to control the direction of movement of particles in a gas to form various functional films on a substrate. PVD technology is an advanced coating production technology, which is also suitable for the sputtering coating process of titanium targets. These technologies enable the formation of films with specific functional or decorative effects on the surface of objects, meeting the needs of different fields for material properties.
Titanium targets are widely used in the field of electronic products, such as the sputtering coating process for the manufacture of mobile phones, computers and other electronic equipment display screens.
In semiconductor manufacturing, titanium and its compounds (such as titanium nitride and titanium oxide) are often used in the manufacture of interface layers, flux films, barrier layers, etc. in semiconductor equipment, and are mainly used as metal sputtering in wafer fabrication, often using PVD process for coating.
In addition, titanium targets are also widely used in the field of decorative coatings, such as glass decorative coatings and wheel decoration coatings, as well as in jewelry, watches, eyeglass frames, knives, home decoration and other fields to manufacture decorative coatings.
The development prospect of titanium target is very broad. With the continuous growth of the global and Chinese titanium target market, innovative manufacturing technology, environmental protection and sustainability, the development of wireless communication and new energy, the application of the pharmaceutical and medical industries, as well as intelligence and digitalization will all promote the progress of the titanium target industry. With the development of technology, such as powder metallurgy, 3D printing and other new technologies, the production and processing efficiency of titanium targets will be further improved, and their microstructure and properties will be enhanced.
