Paper Abstract

The mechanisms of impact damage and erosion that occur in infra-red materials subject to impact by solid particles and water drops are discussed. The elucidation of the damage mechanisms allows identification of the material properties that impart the maximum damage resistance and hence, permit the retention of good optical quality in erosive environments. The principal material properties are the fracture toughness, hardness and elastic wave velocity. Microstructural effects on these properties are briefly discussed.
