Overview
Titanium Arc Target is a high-purity titanium material designed for use in arc evaporation and sputtering processes. These targets are critical in physical vapor deposition (PVD) systems, where they are vaporized to create thin, uniform coatings on substrates. The material's consistency and purity directly influence coating quality, making it essential for industries requiring precise thin-film applications. The manufacturing process involves vacuum melting and precision machining to achieve the desired shape and surface finish. Titanium Arc Targets are commonly available in circular or rectangular forms, tailored to fit specific deposition equipment. Their robustness and resistance to thermal stress make them suitable for high-performance industrial applications.
Physical and Chemical Properties
Titanium Arc Targets exhibit outstanding mechanical and chemical stability, with a density of 4.506 g/cm³ and a melting point of 1668°C. Their high thermal conductivity ensures efficient heat dissipation during the deposition process, reducing the risk of target cracking or warping. The material's low gas content (particularly oxygen and nitrogen) minimizes defects in the deposited films. Chemically, titanium is highly reactive with oxygen at elevated temperatures, forming a protective oxide layer that enhances corrosion resistance. This property is advantageous for coatings exposed to harsh environments. However, the targets must be stored under inert conditions to prevent premature oxidation, which could compromise performance.
Main Applications
The primary use of Titanium Arc Targets is in the production of thin films for semiconductors, where they serve as diffusion barriers or adhesion layers. In the optics industry, they deposit anti-reflective and protective coatings on lenses and mirrors. Decorative applications include durable, scratch-resistant finishes on consumer electronics and automotive parts. Additionally, these targets are employed in aerospace and medical device manufacturing, where biocompatible titanium coatings are required. The ability to alloy titanium with other metals (e.g., aluminum or vanadium) expands their utility in creating films with tailored mechanical and electrical properties.
Safety and Storage
Handling Titanium Arc Targets requires precautions due to the material's pyrophoric nature in powder form. Dust generated during machining or cleaning can ignite spontaneously in air. Workers should use explosion-proof equipment and wear NIOSH-approved respirators when processing the targets. Storage recommendations include keeping the targets in sealed containers under argon or nitrogen to prevent oxidation. Moisture-sensitive applications may require vacuum packaging. Regular inspections for surface contamination or damage are advised to ensure optimal performance during deposition cycles.
B2B Procurement Guide
When sourcing Titanium Arc Targets, prioritize suppliers with ISO 9001 certification and a track record in high-purity materials. Key specifications to verify include: purity level (typically 99.95% or higher), grain size (smaller grains yield smoother coatings), and dimensional tolerances (critical for equipment compatibility). Bulk buyers should negotiate pricing based on volume, with discounts often available for orders exceeding 50 kg. Lead times can vary from 2-8 weeks depending on customization requirements. Consider requesting material test reports (MTRs) and samples for performance validation before large-scale purchases.
