Oxidation and corrosion of ceramics and ceramic matrix composites

Ceramics and ceramic matrix composites are candidates for numerous applications in high temperature environments with corrosive gases and deposits. High temperature oxidation and corrosion issues must be considered for these materials. The most important oxidation and corrosion studies have recently focused on four major areas. These are: (I) oxidation of precursor-based ceramics, (II) studies of the interphase material in ceramic matrix composites, (III) water vapor interactions with ceramics, particularly in combustion environments, (IV) development of refractory oxide coatings for silicon-based ceramics. This paper explores the most current work in each of these areas.
