Applications of titanium targets
Around 2000, the European Union began to conceive and implement the "RoHS Directive" and the "WEEE Directive", and electroplating products were in urgent need of alternatives. So we started to contact PVD technology to replace electroplating.
Titanium targets are round or square made of pure titanium or titanium alloy. "Target" is a term here, mainly used in fields involving physical evaporation or sputtering processes. Titanium targets serve as targeting materials to provide basic substances for product coatings.

Physical Vapor Deposition (PVD) technology refers to the use of physical methods under vacuum conditions to bombard the surface of a material source (solid or liquid) to vaporize into gaseous atoms or molecules, or partially ionize into ions, and pass through the low-pressure gas (or plasma ) process, a technology for depositing thin films with certain special functions on the surface of a substrate. Physical vapor deposition is one of the main surface treatment technologies. At that time, the most exposed targets were aluminum targets, titanium targets, gold targets, etc. At that time, I only knew that the target materials were very expensive.
Today we mainly discuss titanium targets, which include pure titanium and titanium alloys. Titanium targets have the excellent characteristics of titanium itself, such as excellent corrosion resistance (acid and alkali resistance), high strength and low density, as well as good biocompatibility, high temperature resistance, etc. The target will be "bombarded" during the PVD process to produce titanium atoms, so its surface quality has a great impact on the quality of the deposited titanium film. Therefore, the target material usually needs to be finely ground to achieve a surface that is flat enough and free of microcracks and impurities. In this way, high sputtering rate and high purity of the film can be ensured during use.

Application areas of titanium targets
1. Semiconductor industry: Titanium and its mixtures (like titanium nitride and titanium oxide) are many times used to make interface layers, fastening films, obstruction layers, and so forth. in semiconductor gear. It very well may be utilized to store metal movies on silicon wafers and be utilized to interface other electronic components to frame circuits.
2. Covering industry: Titanium targets are utilized in actual fume statement (PVD) and substance fume testimony (CVD) to deliver productive and sturdy coatings. These coatings are utilized in many fields, incorporating sun powered control glass in structures, wear-safe hard coatings for auto parts, and consumption safe coatings for fossil energy gear.
3. Optical industry: In the optical business, titanium targets are utilized to make films with against intelligent, wear-and-wear and oxidation assurance properties. A few explicit applications incorporate eyeglass coatings, camera focal point components, telescopes, magnifying lens and other accuracy instruments.
4. Capacity gadgets: In information capacity gadgets, for example, hard circles, the attractive layer of the hard plate typically utilizes a slim titanium film, which has great warm steadiness and wear opposition.
5. Clinical gadget industry: In the dental field, PVD innovation can be utilized to store titanium films on dental inserts to upgrade holding with bone and further develop biocompatibility.
