Oxidation resistance of Zr- and Hf-diboride composites containing SiC in air plasma up to 2600 K for aerospace applications

Improvement of tribological properties of water‐based ZnO nanoparticles lubricant for zirconium alloy cold rolling by hydroxyethyl cellulose

“…Zirconium alloy has the advantages of low toxicity, corrosion resistance, small thermal neutron absorption cross section, 1 excellent high temperature mechanical properties, good compatibility with the human body, and its compounds have unique chemical and physical properties. Therefore, Zr and Zr products are widely used in nuclear industry, 2 chemical industry, 3 ceramic industry, 4 aerospace, 5 medical industry 6 and so on. In medical surgery, Zr alloys are often made into knee or hip implants, which can reduce friction and improve wear resistance while maintaining overall properties (manufacturability, fracture toughness, ductility, etc.…”

Investigation of the Effect of Supersonic Flow of Dissociated Nitrogen on ZrB2–HfB2–SiC Ceramics Doped with 10 vol.% Carbon Nanotubes

“…Ceramic materials based on zirconium and hafnium diborides, modified with silicon carbide, are of great interest to the scientific community as promising options for use in extreme operating conditions–under high mechanical and thermal loads, including conditions involving aerodynamic heating to temperatures >2000 °C by high-speed air flows [ 1 , 2 , 3 , 4 , 5 , 6 ]. This is due to the high melting temperatures of both the initial components ZrB 2 , HfB 2 , and SiC and their oxidation products ZrO 2 and HfO 2 , the increased thermal conductivity of metal diborides, as well as the good mechanical properties of the materials (in particular, high hardness and strength).…”
