Abstract text

A Hydra-Laser Tri-beam microscope equipped with a femto-second laser beam, four plasma focussed ions (Xenon, Nitrogen, Oxygen and Argon) and a high-resolution electron beam was used to characterised the indentation induced cracking in ZrO2. Results revealed that femto-second laser coupled with the electron imaging is a suitable technique to characterise cracks of microns in width and hundreds of microns in length introduced by the indentation. This paper explores the effect of femto-second laser milling and ion-beam milling parameters on the surface finishing of the ZrO2.
