Corrosion Behavior of Alumina-Aluminum and Silicon …
Pits in the silicon carbide (SiC) composites were deeper than those in the alumina (Al 2 O 3) composites, probably because the SiC particles acted as efficient hodic sites. Pit initiation and propagation occurred at weak spots in the air-formed film, corresponding to phase discontinuities and second-phase particles and to oxygen reduction at the particles or precipitates.

SiAlON – Silicon Alumina Nitride
The α-SiAlON phase is very hard, while the β-SiAlON phase – like normal silicon nitride – exhibits a high level of fracture toughness. The phase fractions of α-SiAlON, β-SiAlON and the grain boundary phase can be adjusted in wide ranges, which makes it possible to adapt the material properties of α/β-SiAlON to meet the requirements profiles of different appliions.
