IN VIVO STUDY OF THE NANOMECHANICAL PROPERTIES OF LEUCITE GLASS CERAMIC PREPARED WITH DIFFERENT SURFACE FINISHING PROCEDURES

Abstract

This paper reports the nanomechanical properties of Leucite glass ceramic prepared with three different surface finishing procedures: polishing, glazing and grinding, using the Nanoindenter. Also, AFM analysis was done in order to determine the roughness parameter Ra. The nanoindentation were performed in order to define the hardness (HV) and Young's modulus (E) of the surface structure using Berkovich diamond pyramid and the experiment was organized in a 3x4 array. Indentation imprints were investigated using the optical and Atomic Force Microscopy. The obtained results of nanomechanical properties mostly depend of applied surface finishing procedures.
