Evaluation of Ultra-High Temperature Ceramics for Aeropropulsion Use

open access: yes, 2001
Among the ultra-high temperature ceramics (UHTC) are a group of materials consisting of zirconium diboride or hafnium diboride plus silicon carbide, and in some instances, carbon.

Corrosion behaviour of three refractory diborides in aqueous solutions

open access: yes, 2008
The corrosion behaviour of three refractory diborides (TiB2, ZrB2 and HfB2) have been compared in acid solutions containing different anions, that is chlorides, sulphates, oxalates citrates and fluorides. TiB2 corrosion is sensitive to both the presence

Case Study: Building an Ultra-High-Temperature Mechanical Testing System

open access: yes, 2013
Ultra-high-temperature ceramics (UHTC\u27s), such as refractory metal borides and carbides, are candidate materials for use in extreme environments associated with hypersonic flight, scram jet engines, rocket propulsion, and atmospheric re-entry.

Effect of RF-magnetron Sputtering Parameters on the Structure of Hafnium Diboride Films

open access: yes, 2018
The study reports about effect of energy factor on the structure formation of nanocrystalline hafnium diboride films. It was shown, that in the magnetron sputtering the change of energy density Ebi delivered to growing film by bombarding ions occurring due to changing in substrate bias potential Us and ion current density js, leads to the formation of ...
