Summary

The surface properties of the system glaze/ceramic body are very important in defining a product's mechanical characteristics and duration in practice. In order to determine a correlation between the hardness of a glazed surface and the progressive degradation due to abrasive action, the Vickers indentation test has been performed on the surfaces of glazed ceramic tiles either as manufactured or as abraded at different steps, in conformity with the European Standard EN 154 concerning the determination of resistance to surface abrasion of glazed ceramic tiles. The experimental results have been discussed and the worn and indented areas have been analyzed by means of optical and electronical microscopy (SEM) in order to understand the damage evolution.
