Inherent Mechanical Damage in Diamond Machined Optical Surfaces

Source

The surface and near-surface regions in diamond machined Cu have been investigated by high resolution transmission electron microscopy, scanning electron microscopy, and scanning transmission electron microscopy. This study has revealed that the near-surface region produced by diamond machining is heavily deformed and that the temperature rise due to the deformation leads to interesting internal oxidation and dynamic recrystallization effects. Surface microstructure is shown to be related to the surface microtopography. A companion paper at this conference presents some correlation of this observed structure with optical properties of the surface including laser damage thresholds.
