Improvement of the mechanical and aesthetic properties of a coating by inkjet technology

Different amounts of ink, made up almost entirely a frit that devitrified abundant small crystals anorthoclase, were applied by inkjet printing onto traditional unfired glaze substrate. The rheological properties the ink and porous texture substrate characterized. fired coatings analyzed SEM–EDX to determine elemental composition at different surface depths, their microstructure was observed. results confirmed validity penetration model, developed in previous study, for describing profile as function amount pore size volume relative average particle size. Microhardness indentation modulus without an application ink-containing determined. values these verified fit Weibull distribution function. containing 400 600 dots per inch (dpi), respectively, displayed best mechanical behavior. study suspension with appropriate physico-chemical characteristics substantially improved aesthetic resulting coating.
