Introduction
The Electroplating Vacuum Coating Polished Titanium Target is a high-purity titanium metal target, which is widely used in vacuum coating processes, especially in the fields of semiconductors, optical components, decorative coatings, etc.
Features
Precision polishing process
The Electroplating Vacuum Coating Polished Titanium Target use multi-level mechanical-chemical combined polishing technology, and the surface roughness of the target material reaches Ra≤0.1μm (conventional products are Ra 0.5-1.0μm). Secondly, our ultra-smooth surface reduces arc discharge during the coating process, so that the film thickness uniformity error is controlled within ±3% (±8% for ordinary targets), which is especially suitable for optical coating, semiconductor packaging and other fields with strict requirements on film consistency.
Fully dense grain structure
We use hot isostatic pressing (HIP) molding process, the grain size reaches ASTM level 8 or above, and the material density is close to 99.95% of the theoretical value. In addition, this structure increases the sputtering rate of the target material by 15% during vacuum sputtering, and the working voltage is stabilized in the range of 400-600V, which is 60% smaller than the fluctuation range of ordinary casting targets, effectively extending the life of the equipment magnetron by more than 2000 hours.
Excellent high temperature resistance
After the target surface is passivated, the annual corrosion rate is less than 0.001g/m² in an acid-base environment of pH 1-14, a high temperature of 500℃ and a vacuum of 10⁻⁶ Pa. Secondly, our special alloy formula (such as adding 0.5% yttrium element) improves the thermal shock resistance by 40%, and can withstand high-frequency start-stop operations for 72 hours in a row, which is suitable for harsh working conditions such as photovoltaic glass coating and aviation component surface treatment.
FAQ
Q: What is an Electroplating Vacuum Coating Polished Titanium Target?
A: An Electroplating Vacuum Coating Polished Titanium Target is a high-purity titanium material used as a target in vacuum deposition systems. It is commonly used for thin-film coating processes, where a titanium layer is deposited onto a substrate to improve properties like corrosion resistance, wear resistance, and aesthetic appearance.
Q: What are the main applications of Electroplating Vacuum Coating Polished Titanium Targets?
A: These targets are primarily used in the production of titanium coatings on products such as semiconductors, optical coatings, medical devices, aerospace components, and decorative finishes. They are also used in the automotive and electronics industries for their durability and conductivity.
Q: Why is titanium used in electroplating vacuum coating?
A: Titanium is chosen for its excellent properties, including high strength, low weight, resistance to corrosion, and biocompatibility. It provides a durable and reliable coating for a wide range of substrates in both industrial and decorative applications.
Q: How does the electroplating process work with a titanium target?
A: In electroplating, a titanium target is placed inside a vacuum chamber, and a current is passed through it. Titanium atoms are released and deposited onto a substrate, forming a thin, uniform coating. The vacuum environment ensures that the process occurs without contamination from air particles.
Q: What is the difference between a polished and non-polished titanium target?
A: A polished titanium target has a smooth and shiny surface, which helps to improve the uniformity and quality of the coating. Non-polished targets may have a rougher surface, which can result in uneven deposition, leading to inferior coatings.
Q: What are the benefits of using a polished titanium target for coating?
A: Polished titanium targets offer better surface quality, enhanced deposition efficiency, and improved coating uniformity. This leads to coatings with fewer defects, smoother finishes, and a more consistent thickness, ensuring higher performance and longevity of the finished product.
Q: How does vacuum coating with titanium targets improve the performance of the substrate?
A: Titanium coatings increase the substrate's resistance to wear, corrosion, and extreme temperatures. This is particularly beneficial for components exposed to harsh environments, such as medical devices, aerospace parts, or electronics, where durability is critical.
Q: What are the environmental benefits of using titanium targets in vacuum coating?
A: Titanium is a sustainable material that is abundant and recyclable. Using titanium in vacuum coating minimizes waste and supports environmentally friendly manufacturing processes, as it reduces the need for hazardous coatings or materials.
Q: What is the typical lifespan of a titanium target in electroplating applications?
A: The lifespan of a titanium target depends on factors like the coating process parameters, the quality of the target material, and the intensity of use. Typically, titanium targets have a long service life, often lasting for several months to a year in continuous use before requiring replacement.
Q: How should Electroplating Vacuum Coating Polished Titanium Targets be maintained?
A: To ensure optimal performance, these targets should be regularly cleaned to remove any buildup of residue or contamination. Maintenance includes inspecting the target for wear, ensuring the vacuum chamber is properly sealed, and checking electrical connections to maintain consistent coating quality.
