Welded Tungsten Boat
What's Welded Tungsten Boat?
Welded tungsten boat is a boat-shaped evaporation carrier assembled from high-purity tungsten sheets through inert gas welding or electron beam welding processes, primarily utilized in vacuum evaporation coating and Physical Vapor Deposition (PVD) processes.
Welded tungsten boat is typically fabricated by splicing and welding a base plate with side walls or multiple tungsten sheet segments, forming a material loading slot in the center and electrode clamping zones at both ends to satisfy large-scale or complex structural evaporation demands, making it highly suitable for non-standardized vacuum thermal field systems.
Advantages of CTIA’s Welded Tungsten Boat
(1) High Structural Flexibility: Enables deep slots, multi-chamber, and complex geometric designs.
(2) Suitable for Large-Size Operations: More suitable for large-area evaporation than stamped or folded structures.
(3) Localized Reinforcement: Critical heating zones can be thickened to improve deformation resistance.
(4) Adaptable to Complex Thermal Fields: Compatible with uneven heat distribution and special equipment designs.
(5) Flexible Customization: Meets non-standard equipment and special process requirements.
Applications of CTIA’s Welded Tungsten Boat
Welded tungsten boat features high density and excellent creep resistance, making it suitable for ultra-high-temperature and corrosive material evaporation processes. Typical applications include:
(1) Refractory Metal Evaporation: Vacuum evaporation and thin-film deposition of high-melting-point metals such as tungsten, molybdenum, and tantalum.
(2) Rare Earth Material Refining: Vacuum purification and evaporation of rare-earth metals and compounds.
(3) Special Alloy Metallurgy: Vacuum melting and purification of advanced alloys.
(4) High-End Ceramic Substrate Coating: Deposition of functional films on ceramic substrates.
(5) High-Temperature Compound Evaporation: Evaporation of corrosive compounds and special oxides.
(6) Research and Extreme Environment Testing: Material research, ultra-high-temperature vacuum experiments, and non-standard equipment testing.
