The thermal erosion of a set of bulk fully dense and 10 vol% porous ZrB2-based ceramics of different composition were machined as sharp wing and tested in an air-fuel mixture flow formed by mixing air and kerosene with an oxygen content ∼5 wt%. The resulting pressure in the combustion chamber was 0.8 MPa and the flow temperature was 1500°C. Microstructural analyses upon the tests evidenced that criteria for material success include high density and high thermal conductivity, along with formation of stable compounds. These results were supported by numerical simulation. Among all tested materials, only ZrB2 - 15 vol% MoSi2 (ZM) met all the requirements and successfully survived the thermal erosion test up to 1200 sec.
期刊介绍：
The Journal of the European Ceramic Society publishes the results of original research and reviews relating to ceramic materials. Papers of either an experimental or theoretical character will be welcomed on a fully international basis. The emphasis is on novel generic science concerning the relationships between processing, microstructure and properties of polycrystalline ceramics consolidated at high temperature. Papers may relate to any of the conventional categories of ceramic: structural, functional, traditional or composite. The central objective is to sustain a high standard of research quality by means of appropriate reviewing procedures.
