Summary

Subsurface degradation due to abrasive phenomena of the proper surface of glazed ceramic tiles was investigated using the Vickers indentation technique. The values of surface and bulk hardness were determined by experimental measurements carried out on the proper surface and on the cross section, respectively, of as-received samples. The direct consequences of abrasive action were clearly evident from the Vickers indentation data for the cross sections of abraded samples. Analysis of the cracking and spoiling processes associated with edge loading of the glaze layer showed generalized weakening of the subsurface layers of abraded ceramic tiles as compared with as-received samples. The results obtained show that the microstructure of the glaze layer can be a critical parameter with regard to fracture and wear mechanisms, detachment of material, and evolution of the damage.
