thermal spray Hafnium carbide-HfC

 Product overview:

Gray metallic powder, with NaCl type cubic crystal structure, is the highest melting point among known single compounds. Hafnium carbide has a high coefficient of elasticity, good electrical and thermal conductivity, a small coefficient of thermal expansion and good impact resistance. It is widely used in cemented carbide, aerospace, atomic energy, electronics, coatings and hard films, etc. In the field of material technology, it is the most important basic material for the manufacture of missiles, launch vehicle nozzle throat linings, satellites, and spacecraft hood parts for thermal protection.

1. Hafnium carbide (HfC) can be used as a modifier for carbon-carbon and carbon-ceramic composite functional materials: hafnium carbide (HfC) modified carbon fiber can greatly improve the strength of carbon fiber, increase fatigue resistance and wear resistance and high temperature resistance The performance and modification effect are very obvious, and all indexes are greatly improved.

2. Hafnium carbide (HfC) is used in cemented carbide, powder metallurgy and other fields, which can improve the strength and corrosion resistance of cemented carbide, and the effect is more obvious than that of zirconium carbide (ZrC);

Performance characteristics:

1. High purity, no impurity phase detected by XRD, low content of metal impurity elements detected by GDMS/ICP;

2. Concentrated particle size distribution, good sphericity, good fluidity, no tube blocking, good quality of 3D printing and thermal spraying.
