DIMOX Processed Al2O3/SiC CMCs through Al Alloy: Physical Properties

Ceramic materials have properties that make them ideal candidates for many elevated temperature applications such as heat exchangers and turbine engines components. Due to the refractory nature of ceramics they are at times the only choice for a material that can potentially satisfy the most demanding requirements particularly at high temperatures. In addition to offering high melting or decomposition temperatures many ceramics posses other attractive features such as low density high temperature strength high hardness and resistance to creep deformation thermo-chemical stability and lack of reactivity in contact with other materials and various atmospheres and last but not least high wear resistance. work is aimed at optimizing the DIMOX process and at obtaining a suitable process window that enables fabrication of large SiCp/Al2O3 composite specimens for the measurement of physical properties.
