Residual stress determination and subsurface microstructure in ground and polished alumina/silicon carbide nanocomposites and monolithic alumina ceramics

Abstract:

The surface residual stress state induced by grinding and polishing an alumina/silicon carbide nanocomposite and monolithic alumina has been investigated using Hertzian indentation and fluorescence spectroscopy. Specimens were ground and then polished with diamond slurry with grit sizes ranging between 8 eta m and 1 mu m. The results show that the surface residual stress state in the nanocomposites is more sensitive to surface treatment than that in the monolithic alumina. Surfaces of both ce...
