Metallography Ceramic Matrix Composites

Ceramic Matrix Composites (CMC's)
Specimen Preparation (Class 10 Procedures)

Description:

Ceramic matrix composites are used for either their high temperature resistance or there low wear characteristics.

Preparation Challenge:

Specimen preparation of these materials requires that the brittle phases be maintained.

Examples:

CERAMIC MATRIX COMPOSITE PROCEDURES
SiC fiber - Silicon Nitride Matrix	Hafnium Diboride in a Boron Nitride Matrix
SiC particles - Silicon Nitride Matrix	SiC particles - Zirconium Diboride Matrix
