Titanium Investment Casting Inertization
Titanium investment casting inerting prevents reactions between titanium melt and mold materials through special coatings and vacuum casting techniques. This ensures a clean, smooth investment casting.
Physicochemical Mechanism of Action
Titanium melts at high temperatures and is prone to reactions with many materials, especially oxidizable substances. Inerting with special oxide ceramic layers and vacuum casting technology prevents these reactions by removing air from the structure and forming a protective layer.
Metallurgical Relevance & Welding Risks
Without inerting, titanium investment castings may be incompletely cast or damaged, leading to quality issues. Using oxide ceramic layers and vacuum casting technology ensures a clean, defect-free mold fill and prevents the formation of cracks or corrosion.
Workshop Practice & Action Guidelines
Use oxide ceramic layers like titanium dioxide or silicon dioxide on the mold material. Ensure the casting table is in a vacuum and the temperature is controlled. An inerting time of at least 30 minutes is recommended to form a complete protective layer.
