In the development trend of military-civilian integration and military-civilian integration, we have formed a coordinated development pattern of "production generation, R&D generation, application generation, and exploration generation", actively responding to national policies and supporting Made in China. In the field of military industry, a generation of equipment requires a new generation of materials to support, and tantalum metal is born to comply with new technologies.

Gun body inner coating material:

Tantalum or tantalum alloy coatings are considered to be the ideal coating system to replace ablation-resistant, erosion-resistant plated Cr coatings. The tantalum coating is applied to the gun barrel and has the purpose of long-term flame retardant gas ablation. The sputtered Ta layer should be mainly composed of α-Ta, the thickness should be at least 75μm, and the coating should have sufficient bonding with the substrate in all directions. force to resist thermal shock and high shear stress during artillery firing.

armor piercing projectile:

In the 1980s, a new type of warhead - an armor-piercing bullet formed by explosion was successfully developed, mainly using tantalum on the butterfly bushing close to the high-energy explosive. When the explosive is detonated, the butterfly-shaped disc is deformed into a long, stable, armor-piercing projectile, which accelerates to the target.

With the development of armor materials, modern anti-armor warheads have higher and higher requirements for explosive-shaped ammunition-type cover materials. The drug-type cover is required to form a longer and stable jet, and the drug-type cover material has the properties of high density, high sound velocity, good thermal conductivity, and high dynamic elongation at break. Tantalum has high density (16.6g/cm3) and good dynamic characteristics, and is a material mainly used for explosive forming ammunition cover in foreign research. Ta is widely used in missiles as the material of explosive forming ammunition type cover. Ballistic experiments show that the penetration of Ta is 30% to 35% higher than that of Cu, which can reach 150mm.

Ultra-high vacuum getter material:

Ultra-high vacuum getter material (tantalum-alloy) is used in night vision equipment in national defense conventional weapons. Using 15% tantalum material as the skeleton, using titanium as the adsorbent for hydrogen, oxygen, nitrogen, carbon monoxide, carbon dioxide, water vapor, methane, neon and other gases to improve the service life of the getter material, this material can be applied to active infrared The infrared camera tube in the night vision device and the low light tube in the passive low-light night vision device ensure that the vacuum tube maintains a long-term high vacuum, so as to achieve high efficiency, long life and improve the clarity of the night vision device.
