What is the block of titanium?
Titanium Round Target Block is a type of Titanium Target Block and a Titanium Forging that we often process in Titanium Material. Titanium targets play an important role in science and industry because of their outstanding properties. Understanding their fundamental properties is not only critical for materials scientists and engineers, but also guides the further development and innovation of titanium target applications. The following is a detailed analysis of the basic properties of titanium targets, designed to provide a comprehensive, process-oriented and professional in-depth perspective.
Physical Properties Density: The density of titanium targets is about 4.5 g/cm³, and this low density makes titanium and its alloys very popular in aerospace and automotive manufacturing industries, as they help reduce overall structural weight and improve energy efficiency.
Melting Point: Titanium has a melting point of approximately 1,668°C (3,034°F). This high melting point indicates that titanium targets are able to remain stable in high-temperature environments, making them ideal for the manufacture of high-temperature resistant parts and materials.
Chemical Resistance to Corrosion: Titanium target exhibit excellent resistance to corrosion in many corrosive environments, including seawater and a wide range of acid and alkali solutions. This property allows titanium and its alloys to be used in a wide range of applications in the chemical industry, marine engineering and other fields.
Chemical Stability: Titanium reacts with atmospheric oxygen, nitrogen and other elements at room temperature to form a stable oxide film which resists further corrosion. This natural anti-corrosion barrier further enhances the range of applications for titanium targets.
Mechanical Properties Hardness: Titanium targets have good hardness and can withstand testing for applications that require resistance to wear and long-term use. This hardness also ensures durability during processing and reduces the need for maintenance.
Toughness: Despite its high hardness, titanium targets also show excellent toughness. This means that it resists fracture and maintains integrity when subjected to impact or high pressure. This property is particularly important when manufacturing high-performance equipment and components that require extreme reliability.
Impact of Processing: The hardness and toughness of titanium targets have a direct impact on their processing. Although the high hardness increases the difficulty of machining, but through the selection of appropriate processing technology (such as high-speed cutting, EDM, etc.) and parameter adjustment, can be effectively processed into the required shape and size. At the same time, its excellent toughness makes the titanium target material have better fracture resistance during processing, reducing the loss in the production process.
Comparison of the advantages and disadvantages of different specifications of titanium targets
Thickness
Thicker titanium targets have a longer sputtering life, reducing the frequency of target changes and improving work efficiency. However, the film thickness distribution is not uniform, which needs to be improved by rotating the target. Thinner titanium targets have a more uniform thickness distribution.
Purity
High purity titanium target (e.g. 99.99%) prepared by the high purity of the film layer, good performance. However, the target material depletes quickly, increasing operating costs. Although low purity titanium target has the cost advantage, but the impurity content of the deposited film is high, which affects the performance of the film layer. Density
Titanium targets with high density have good densification and strong adhesion. However, too high density will also increase the internal stress of the film. Moderate density of titanium target can obtain a balanced performance of the film layer.
Surface roughness
Bright and flat titanium targets can deposit better surface quality layers. However, over-polishing can also lead to particle shedding problems. Moderate surface roughness helps to improve film adhesion.
Size
Large titanium targets are efficient, but have poor uniformity and uneven film thickness distribution. Smaller targets provide a uniform layer but are less efficient.
Strength
High strength titanium target has high mechanical strength, long service life and good wear resistance, but the production process is more difficult. Ordinary titanium targets have lower mechanical strength, are more prone to wear and tear, and have a short service life.
Density uniformity
Density uniformity of the titanium target can make the film layer in all areas of the same degree of density, to obtain a uniform performance of the film layer. Uneven density of the target material will lead to unstable quality of the film layer.
Impurity type
Different impurity elements have different effects on the performance of titanium film. For example, Fe contamination seriously affects the electrical properties of the film, while Si mainly affects the mechanical properties. Selection of titanium targets with suitable impurities can optimize the performance of the film layer.
Price
The high price of titanium target usually has excellent performance, but the cost of use is also high. Choosing cost-effective products can reduce costs while ensuring the quality of the film layer.
