Summary

The effects of long term oxidation (up to 100 h) in the temperature range 600-1500°C on mechanical strength and electrical resistivity are examined in different types of composites: AlN-SiC, AlN-SiC-MoSi2, Si3N4-MoSi2 and Si3N4-TiN. The degradation of strength and of electrical conductivity are related to the characteristics of the oxide scale and of the sub-surface damage after oxidation.
