특징 및 장점
The high purity and spherical morphology make HDH powder suitable for additive manufacturing, metal injection molding, pressing and sintering, thermal spraying, welding, and other fabrications that require high density and quality.
Key benefits over other titanium powder varieties:
- Higher purity with lower interstitial elements
- Improved flowability due to spherical shape
- Better packing density and sinterability
- Excellent mechanical properties
- Good chemical stability at high temperatures
However, HDH powder can be more expensive than other varieties due to the extensive processing required to achieve the purity levels.
HDH titanium powder, with a high purity, can be used across various industries. It is produced via the Armstrong process, a process known as hydrogenation/dehydrogenation (HDH).
Manufacturing Process
The process of titanium HDH powder involves multiple stages:
- Melting: Commercially pure titanium ingots are melted into liquid form. Common feedstocks are titanium sponge, scrap, and alloy ingots.
- Hydriding: The molten titanium reacts with hydrogen gas to produce titanium hydride (TiH2). Cooling and crushing creates brittle titanium hydride chunks.
- Dehydriding: The TiH2 is treated in a vacuum at temperatures above 600°C, decomposing it back into titanium powder and releasing hydrogen. This powder has high oxygen content.
- Vacuum Purification: Multiple vacuum distillation cycles are used to reduce oxygen, nitrogen and hydrogen levels to ≤0.2%, achieving high purity HDH titanium powder.
The HDH process allows precise control over powder characteristics like particle size distribution, morphology, purity level, and microstructure. The powder can be tailored to meet application requirements.
