Wear Resistance of Metal Oxide Sol-Gel Coatings Deposited over Ceramic Glazes
This paper analyse the wear resistance of high reflective metal oxide films of TiO2 (anatase), Fe2O3 (hematite), ZrO2 (Zirconia) and SnO2 (Casiterite) deposited by screen printing over a conventional ceramic glaze (molar composition 0,2CaO.0,15ZnO.0,05K2O.0,1Al2O3 0,45SiO2.0,05ZrO2). All oxide coatings increase the gloss of the substrate producing a lustre effect. Anatase films stand out for their high gloss valour and low roughness Ra. Likewise, all lustres improve the wear resistance of the glaze substrate. Hematite and casiterite coatings stand out for their relatively high wear resistance maintaining relatively high reflectivity.
