Static Fatigue Behavior of Structural Ceramics in a Corrosive Environment

Abstract

Flexure testing was used to determine the effects of sodium sulfate induced corrosion on the static fatigue behavior of several structural ceramics between 800 C and 1200 C. The results showed that the static fatigue behavior of a high purity, full-dense alumina and a Ce-TZP are unaffected by this corrosive environment. However, the static fatigue behavior of a MgO-doped Si3N4 and, to a lesser degree, a Y-TZP are affected by the introduction of sodium sulfate.
