What are the Outstanding Performances of Tantalum Coating in All Walks of Life?

Tantalum metal coating products are widely used in the industrial field and drive the industrial demand with innovative core technology.

Aerospace field

At present, tantalum is increasingly used in the high-temperature alloy, which is a good structural material for jet aircraft, rocket, and missile. The high temperature and oxidation resistance properties of tantalum coating can be used to make engine parts for satellite launches and rockets, propulsion afterburner and nozzle valves, etc. In addition, tantalum coating can improve the high-temperature strength and room temperature fracture toughness of the alloy system and can be widely used in the blade, seal and nozzle, or gas cleaning system components, etc.

Military industry

Tantalum and tantalum alloy have high density, high dynamic elongation, and arson, which can be widely used in missile manufacture. The low friction and high-temperature resistance of tantalum coating can be used to accelerate the gun barrel and greatly extend its service life. Tantalum coating technology applied to military vessels can greatly improve their corrosion resistance to seawater, which is one of the most important application directions of tantalum in military industry.

Petrochemical field

Tantalum is reputed to be the most corrosion-resistant metal. At room temperature, tantalum does not react with hydrochloric acid, concentrated nitric acid or even aqua regia, and ordinary inorganic salts cannot corrode it. Tantalum coating on the surface of valves, pipes, fittings, heat exchangers, evaporators, reactors and other equipment can greatly improve the equipment’s corrosion resistance.

Biomedical field

Tantalum metal has a long history in medical applications, including pacemaker manufacturing, vascular clip manufacturing, femoral stem prosthesis manufacturing, skull defect repair, etc., and is an ideal material for surgical implantation. The three-position porous structure of tantalum for clinical use is conducive to the adhesion, differentiation, and growth of osteoblasts and promotes bone growth. In addition, the elastic modulus, fatigue resistance and friction coefficient of porous tantalum are similar to normal bone tissue and show good long-term biocompatibility, corrosion resistance, bone induction, and regeneration capacity, which can accelerate the healing process and greatly reduce the rate of rejection reaction. It has a promising prospect in the application of bone surgery.


Marine engineering

Because of its excellent corrosion resistance and good mechanical properties, tantalum metal is extremely suitable for extremely harsh corrosion environment and is used in petrochemical equipment, Marine engineering materials, etc.

A stable bond is formed between the tantalum coating and substrate, which will not flake under the corrosion and impact of seawater. The application of tantalum coating in the weld zone can prevent the formation of austenite and lead to grain coarsening and embrittlement. Furthermore, tantalum coating technology requires a low temperature, which can strictly control the temperature between layers and prevent the softening of the heat affected zone. With the surface alloy coating technology, tantalum will greatly extend the service life of Marine engineering materials, reduce the cost of materials and meet the material demand.

Nuclear power industry

Tantalum coating has excellent oxidation resistance and corrosion resistance, and it is also excellent in strength and hardness, which can be applied to the melting crucible and agitator for producing nuclear raw materials, as well as the coating material of tungsten solid target in the high-energy accelerator.
